How to Become an Engineer in the United States: 2026 Ultimate Guide

Becoming an engineer is not one career path. It is a family of careers with different technical problems, workplaces, and specializations.

We researched the engineering occupations covered by the U.S. Bureau of Labor Statistics (BLS). We also reviewed their education, duties, work environments, wages, outlook, and licensing requirements.

This guide brings that information together into one practical pathway. It covers 18 engineering careers, from civil and mechanical engineering to aerospace, biomedical, nuclear, and petroleum engineering.

The goal is not simply to explain how to earn an engineering degree. It is to help you understand what happens before, during, and after that degree.

We also examined authoritative licensing information from NCEES, ABET, CareerOneStop, and the U.S. Nuclear Regulatory Commission. Where a recommendation reflects our career analysis rather than a formal requirement, we identify it as such.

What Does an Engineer Do?

At its broadest level, engineering is applied problem-solving.

Engineers use mathematics, science, technology, and design principles to solve practical problems. They design products, structures, machines, processes, systems, and technologies.

The work usually follows a similar cycle.

First, an engineer identifies a problem or requirement. The engineer then studies constraints, develops possible solutions, tests them, and improves the final design.

The specific work changes dramatically between disciplines.

A civil engineer may design a bridge and inspect construction work. A mechanical engineer may develop an automated manufacturing system. A biomedical engineer may design a medical device.

A computer hardware engineer may develop processors or circuit boards. An environmental engineer may design systems that improve water quality.

Aerospace engineers work on aircraft, spacecraft, satellites, and related systems. Marine engineers and naval architects work with vessels, propulsion systems, and offshore structures.

Engineering is therefore not simply a desk job. Depending on the discipline, engineers may work in offices, laboratories, manufacturing plants, construction sites, mines, hospitals, shipyards, or offshore facilities.

Most engineering occupations require full-time work. Some roles involve more than 40 hours per week, especially when projects face deadlines or technical problems.

The BLS reports a 2024 median annual wage of $97,310 for engineers as an occupational group. The median for all U.S. occupations was $49,500.

That figure is useful as a benchmark. Individual engineering careers vary considerably.

Civil Engineering

Civil engineers design, build, and maintain infrastructure.

Their work can involve buildings, bridges, highways, airports, water systems, dams, and other physical infrastructure. The discipline also includes specialized areas such as structural, geotechnical, transportation, construction, and water resources engineering.

A civil engineer may spend part of the week reviewing drawings and calculations. Another day may involve visiting a construction site and checking progress against specifications.

The work combines office-based design with practical field work. Engineers must understand technical standards, construction methods, materials, safety requirements, and project constraints.

A bachelor’s degree is the typical entry-level education. Civil engineering students normally study mathematics, physics, mechanics, materials, structural analysis, and design.

Licensure can become particularly important for civil engineers. Engineers who provide services directly to the public or approve engineering work may need a Professional Engineer license.

BLS reported a $99,590 median annual wage for civil engineers in 2024. Employment is projected to grow 5 percent from 2024 to 2034, with about 23,600 openings projected annually.

Civil engineering is therefore not the highest-paid engineering field. It does, however, offer a large employment base and many annual openings.

Mechanical Engineering

Mechanical engineering is one of the broadest engineering disciplines.

Mechanical engineers design, develop, test, and improve machines and mechanical systems. Their work can involve engines, manufacturing equipment, heating and cooling systems, robotics, vehicles, and energy systems.

They often work with computer-aided design and simulation tools. Testing is also central to the profession.

A mechanical engineer may design a component, simulate its performance, build a prototype, and then test it under controlled conditions.

The work spans manufacturing, transportation, energy, research, and engineering services. Some mechanical engineers work closely with production teams to integrate automation into manufacturing systems.

A bachelor’s degree in mechanical engineering or a related field is the typical entry point.

Mechanical engineering had a $102,320 median annual wage in 2024. BLS projects 9 percent employment growth between 2024 and 2034, which is faster than the average for all occupations. About 18,100 openings are projected annually.

The field is especially interesting for students who enjoy physics, machines, design, manufacturing, and practical problem-solving.

Industrial Engineering

Industrial engineers focus on efficiency.

They examine how people, equipment, materials, information, and processes work together. Their goal is often to make a system safer, faster, more efficient, or less expensive.

An industrial engineer might analyze a manufacturing line. Another might redesign a hospital workflow or improve the movement of materials through a warehouse.

The discipline combines engineering with statistics, operations research, economics, data analysis, and human factors.

This makes industrial engineering different from many traditional engineering disciplines. The engineer is often improving an entire system rather than designing one physical product.

A bachelor’s degree is the typical entry-level education.

Industrial engineers earned a $101,140 median annual wage in 2024. BLS projects 11 percent employment growth from 2024 to 2034, the highest growth rate among the engineering occupations in our dataset.

That combination makes industrial engineering worth considering for students interested in operations, analytics, manufacturing, logistics, and process improvement.

Electrical Engineering

Electrical engineers work with electricity, electronic systems, power, communications, and related technologies.

Their work can involve electrical power systems, motors, control systems, communications equipment, and other electrical technologies.

Electrical engineering is particularly broad. One engineer may work on power infrastructure, while another works on renewable energy systems or control technology.

The field has strong connections with electronics, computing, telecommunications, automation, and energy.

A bachelor’s degree in electrical engineering or a related field is the normal entry point.

Electrical engineers had a $111,910 median annual wage in 2024. The broader electrical and electronics engineering occupation is projected to grow 7 percent from 2024 to 2034.

Electrical engineering is also one of the disciplines where your choice of specialization can significantly influence your working environment.

A power engineer may spend time around electrical infrastructure. A controls engineer may spend more time working with industrial automation systems.

Electronics Engineering

Electronics engineers design and develop electronic components and systems.

Their work can involve circuit boards, communications systems, sensors, control equipment, and other electronic technologies.

Electronics engineering overlaps considerably with electrical engineering. The distinction becomes clearer when you consider the systems being designed.

Electrical engineering often has a stronger connection to electrical power and larger electrical systems. Electronics engineering focuses more heavily on electronic components and circuitry.

The BLS reported a $127,590 median annual wage for electronics engineers, except computer, in 2024. The highest-paid 10 percent earned more than $199,060.

The field is relevant to industries such as telecommunications, semiconductor manufacturing, consumer electronics, medical technology, and aerospace.

Students interested in electronics should expect substantial coursework in mathematics, physics, circuits, digital systems, and related engineering sciences.

Computer Hardware Engineering

Computer hardware engineering is one of the highest-paid engineering careers in the BLS data.

Computer hardware engineers research, design, develop, and test computers and related equipment. Their work can involve processors, circuit boards, memory devices, and other hardware components.

They may work in laboratories, manufacturing facilities, research environments, and computer systems companies.

The occupation sits at an interesting point between electrical engineering and computing. Engineers need to understand physical hardware while also considering how that hardware interacts with software.

A bachelor’s degree in computer engineering or a related field is the typical entry-level requirement.

The 2024 median wage was $155,020, the highest among the engineering occupations in this dataset. BLS projects 7 percent employment growth through 2034. About 4,700 openings are projected annually.

This career can be particularly attractive to students interested in semiconductors, processors, embedded systems, electronics, and computing hardware.

Petroleum Engineering

Petroleum engineers develop methods for extracting oil and gas from underground reservoirs.

Their work involves evaluating reservoirs, designing extraction methods, and improving production. Some work with offshore operations.

The occupation is closely connected to geology, drilling technology, reservoir engineering, and energy production.

A bachelor’s degree in petroleum engineering or a related engineering field is the typical entry route.

Petroleum engineering remains one of the highest-paying engineering careers. The 2024 median annual wage was $141,280. The highest-paid 10 percent earned more than $228,790.

The employment outlook is more modest. BLS projects 1 percent growth from 2024 to 2034.

This illustrates an important career-planning principle.

High pay does not automatically mean strong employment growth. Anyone choosing petroleum engineering should consider both the compensation and the longer-term industry outlook.

Aerospace Engineering

Aerospace engineers design, develop, and test aircraft, spacecraft, satellites, and missiles.

Their work covers areas such as aerodynamics, propulsion, structural design, guidance, navigation, controls, robotics, and instrumentation.

Most aerospace engineers work in office environments. Some also work in manufacturing facilities, laboratories, or testing environments.

Defense-related projects can have additional requirements. Engineers working on certain national defense projects may need security clearance.

A bachelor’s degree in aerospace engineering or a related engineering discipline is the typical entry point.

The 2024 median wage was $134,830. Employment is projected to grow 6 percent between 2024 and 2034, with about 4,500 openings annually.

Aircraft efficiency, satellite development, drones, and space activity are among the factors identified by BLS as supporting demand.

Nuclear Engineering

Nuclear engineers work with nuclear energy, radiation, nuclear materials, and related systems.

Their work can involve nuclear power generation, reactor systems, safety, fuel cycles, and research.

The discipline requires a strong foundation in mathematics and physics. Nuclear engineers may also work in government, engineering services, power generation, and research.

The 2024 median annual wage was $127,520. The highest-paid 10 percent earned more than $187,430.

The employment outlook is unusual.

BLS projects a 1 percent decline from 2024 to 2034. However, about 800 openings are still projected annually, mainly because workers leave the occupation or retire.

Nuclear engineers working directly with reactor operations may encounter additional licensing requirements. The NRC licenses reactor operators and senior reactor operators through a separate process.

That licensing should not be confused with ordinary engineering licensure.

Chemical Engineering

Chemical engineers use chemistry, physics, mathematics, and engineering to design and improve industrial processes.

They may design equipment, production processes, and systems used to manufacture chemicals, fuels, pharmaceuticals, food products, plastics, and other materials.

The work can involve laboratories, manufacturing plants, offices, and production facilities.

Chemical engineering is especially suitable for students who enjoy chemistry but want to apply it to industrial systems.

A bachelor’s degree in chemical enginnering is the typical entry-level requirement.

Chemical engineers had a $121,860 median annual wage in 2024. BLS projects 3 percent employment growth from 2024 to 2034.

The discipline can also provide pathways into pharmaceuticals, energy, advanced materials, biotechnology, and environmental technology.

Bioengineering and Biomedical Engineering

Bioengineers and biomedical engineers combine engineering with biology and medical science.

They may design medical devices, artificial body parts, diagnostic equipment, rehabilitation technologies, computer systems, and other healthcare technologies.

Some work in manufacturing. Others work in research facilities, hospitals, laboratories, or engineering services.

The discipline has become increasingly connected with digital health, medical devices, biotechnology, data analysis, and healthcare technology.

A bachelor’s degree in biomedical engineering, bioengineering, or a related engineering field is the usual starting point. Some positions require graduate education.

The 2024 median annual wage was $106,950. BLS projects 5 percent employment growth through 2034, with about 1,300 openings annually.

Students interested in this field should consider both engineering fundamentals and biological sciences.

Our detailed biomedical engineering jobs roadmap examines emerging specializations and transition routes into this field.

Environmental Engineering

Environmental engineers apply engineering principles to environmental problems.

Their work can involve water treatment, air pollution, waste management, environmental compliance, and pollution control.

Some work on projects designed to improve drinking-water quality. Others develop systems that reduce industrial pollution or manage waste.

The occupation combines engineering with chemistry, biology, environmental science, and regulatory requirements.

A bachelor’s degree is the typical entry-level education.

Environmental engineers earned a $104,170 median annual wage in 2024. BLS projects 4 percent growth between 2024 and 2034, with about 3,000 openings annually.

Federal government employment had a particularly high median wage in the BLS data, at $120,830 in 2024.

Environmental engineering can suit students who want technical work connected to water, climate, pollution, public health, and sustainability.

Materials Engineering

Materials engineers develop, process, test, and select materials for products and systems.

They work with metals, ceramics, plastics, composites, and other materials.

The work often begins with a practical question.

Why did a component fail? Which material will withstand higher temperatures? Can a product become lighter without losing strength?

Materials engineers answer questions like these through testing, analysis, and design.

The field connects closely with manufacturing, aerospace, automotive engineering, electronics, energy, and research.

The 2024 median wage was $108,310. BLS projects 6 percent employment growth from 2024 to 2034.

A bachelor’s degree is normally sufficient for entry-level work. Advanced degrees can become useful for research-intensive positions.

Mining and Geological Engineering

Mining and geological engineers help develop methods for extracting minerals and other geological resources.

Their work can include mine design, resource assessment, extraction methods, safety, environmental considerations, and production planning.

The work environment can differ substantially from many other engineering careers.

An engineer may spend time in an office developing designs. Another period may be spent at a mine, quarry, processing facility, or other field location.

The occupation includes mining engineers, geological engineers, and mining safety engineers.

The 2024 median wage was $101,020. BLS projects 1 percent employment growth from 2024 to 2034.

Mining and geological engineering can suit students who enjoy engineering but prefer field-based work, natural resources, geology, and large physical operations.

Marine Engineering and Naval Architecture

Marine engineers and naval architects design and evaluate marine vessels and their systems.

Their work can involve ship hulls, propulsion systems, power systems, machinery, and other marine equipment.

They may work in offices, shipyards, manufacturing facilities, coastal environments, or at sea.

The occupation also extends beyond conventional ships. Some professionals work on offshore projects involving oil platforms, wind turbines, ports, or seawalls.

Marine engineers should not be confused with ship engineers. Ship engineers are responsible for operating and supervising ship machinery rather than designing marine vessels.

The 2024 median wage was $105,670. BLS projects 6 percent employment growth from 2024 to 2034.

A bachelor’s degree is the usual starting point. Entry-level marine engineers do not generally need a PE license, although experienced professionals may pursue one.

Agricultural Engineering

Agricultural engineers apply engineering to agriculture and related systems.

Their work can involve agricultural machinery, power systems, irrigation, food processing, structures, soil and water conservation, and environmental problems.

The discipline combines engineering with biology, agriculture, environmental science, and mechanical systems.

An agricultural engineer may design safer food-processing equipment. Another may work on irrigation systems or agricultural machinery.

BLS identifies analytical ability, communication, mathematics, and problem-solving as important qualities for agricultural engineers.

The 2024 median annual wage was $84,630. Employment is projected to grow 6 percent from 2024 to 2034.

The field can be a good fit for students who want engineering work connected to food systems, agriculture, water, machinery, and natural resources.

Health and Safety Engineering

Health and safety engineers use engineering principles to prevent accidents, injuries, and other hazards.

They may design safer equipment and systems. They may also investigate incidents and recommend changes to reduce future risks.

Their work can involve manufacturing plants, government agencies, engineering services, construction, and consulting.

The field has an interesting combination of engineering and human factors. Engineers must understand how equipment, processes, workplaces, and people interact.

The 2024 median wage was $109,660. The highest-paid 10 percent earned more than $166,670.

BLS projects 4 percent employment growth from 2024 to 2034.

The field can suit engineers who want technical work with a strong connection to workplace safety, risk management, compliance, and accident prevention.

How to Become an Engineer in the United States

The careers above differ in their technical focus. The basic education-to-employment pathway is more consistent.

For most aspiring engineers, the journey looks like this:

High school preparation → engineering degree → practical experience → entry-level engineering work → optional or discipline-specific licensure → specialization → career advancement

Let’s examine each stage.

Step 1: Build a Strong High School Foundation

Engineering starts with mathematics and science.

You do not need to know your exact engineering specialty at 15 or 16. You do need a solid academic foundation.

Mathematics

Mathematics is central to engineering.

Algebra and geometry provide the foundation. Trigonometry becomes important for technical calculations. Calculus becomes central to many university engineering programs.

Statistics and probability also become important in fields such as industrial engineering, systems engineering, and risk analysis.

If you struggle with mathematics, do not automatically conclude that engineering is impossible. Instead, identify the specific gaps and address them before university.

Physics

Physics provides another major foundation.

Mechanics helps explain forces, motion, energy, and structures. Electricity and magnetism become important for electrical and electronics engineering.

Thermodynamics is important in mechanical and chemical engineering. Fluid mechanics becomes relevant to fields such as aerospace, civil, mechanical, and marine engineering.

Chemistry

Chemistry is particularly important in chemical, environmental, materials, biomedical, and some agricultural engineering pathways.

A strong chemistry foundation also helps students understand materials, reactions, energy, and industrial processes.

Biology

Biology is not equally important across all engineering disciplines.

It becomes particularly useful for biomedical and bioengineering students. Environmental and agricultural engineering students can also benefit from biological sciences.

Computing

Computing skills are increasingly useful across engineering.

Programming can support data analysis, simulation, automation, controls, and hardware development.

You do not need to become a professional programmer before studying engineering. Basic computational thinking is the more important starting point.

Step 2: Choose the Right Engineering Degree

For most of the engineering occupations covered here, a bachelor’s degree is the standard entry-level qualification.

That does not mean every engineering degree produces the same career options.

Your choice of major matters.

Someone targeting aerospace engineering might study aerospace engineering or a closely related field. Someone targeting biomedical engineering might choose biomedical engineering, bioengineering, mechanical engineering, or another related discipline.

The best choice depends on the career you want after graduation.

Should You Choose an ABET-Accredited Program?

In the United States, accreditation deserves serious attention.

ABET accredits engineering and engineering-related programs against established educational standards.

ABET says accreditation can support entry into technical professions because licensure, registration, and certification pathways often require an accredited educational background. It also notes that accreditation can improve professional mobility.

However, do not interpret that as meaning every engineering job legally requires an ABET-accredited degree.

Requirements depend on the occupation, employer, state, and intended career path.

The distinction becomes particularly important if you expect to pursue professional engineering licensure.

Before enrolling, check whether the specific program is accredited. Do not assume that an entire university is “ABET accredited.”

ABET accredits programs, not universities as a whole.

Its current accreditation criteria cover engineering programs across disciplines including civil, electrical, computer, industrial, biomedical, chemical, and agricultural engineering.

Should You Get a Master’s Degree?

Not necessarily.

A bachelor’s degree is enough for entry into many engineering jobs.

A master’s degree becomes more useful when you want deeper specialization, research work, technical leadership, or certain advanced positions.

A Ph.D. is more relevant to advanced research and university teaching.

BLS notes that engineers with graduate degrees are more likely to move into research and development and postsecondary teaching.

Do not spend extra years in graduate school simply because you assume every engineer needs an advanced degree.

Start with the career you want.

Then determine whether that career actually rewards the additional qualification.

Step 3: Gain Practical Engineering Experience

An engineering degree teaches principles.

Work experience teaches you how those principles behave under real constraints.

That difference matters.

A classroom problem normally has defined inputs and an expected solution. Real engineering projects involve budgets, deadlines, regulations, suppliers, incomplete information, safety requirements, and changing client expectations.

That is why practical experience matters.

Internships

Engineering internships are one of the most useful ways to gain early experience.

Look for opportunities related to your intended discipline.

A mechanical engineering student could target manufacturing, automotive, robotics, or energy companies. A civil engineering student could look at construction firms, infrastructure consultancies, transportation agencies, or engineering services companies.

Co-op Programs

Cooperative education programs allow students to spend substantial periods working in industry.

They can provide more sustained experience than a short internship.

They can also help you determine whether you actually enjoy the engineering work you intend to pursue.

Capstone Projects

University design projects can demonstrate practical ability.

Do not simply list “capstone project” on your resume.

Explain what you designed, what problem you solved, what tools you used, and what the final result achieved.

That turns an academic project into evidence of applied skills.

Entry-Level Engineering Work

New engineers usually begin under the supervision of more experienced professionals.

They gradually take on more complex projects and greater independence.

BLS describes this progression across engineering occupations. Experienced engineers may eventually supervise teams, manage projects, become technical specialists, or move into research and teaching.

Step 4: Understand Engineering Licensure

This is where many explanations of engineering careers become too simplistic.

A bachelor’s degree does not automatically make you a licensed Professional Engineer.

Licensure is controlled by individual states.

The exact requirements can therefore differ.

The FE Exam

The Fundamentals of Engineering (FE) exam is generally the first major examination in the professional engineering licensure pathway.

NCEES describes it as the first step toward becoming a licensed Professional Engineer. It is designed primarily for students close to completing an undergraduate engineering degree and recent graduates.

The FE exam tests foundational engineering knowledge.

It is not the same as the PE exam.

Engineer Intern or Engineer-in-Training Status

People who pass the FE exam are commonly referred to as Engineer Interns or Engineers-in-Training.

However, the precise designation and registration process depend on the state.

Do not assume that simply passing the FE exam automatically gives you the same legal status in every state.

Check your state board.

Gain Engineering Experience

The next stage involves relevant engineering experience.

A common benchmark is four years of progressive experience. However, state requirements can differ.

The experience may need to be supervised by a licensed Professional Engineer.

This is another reason to investigate your intended state’s requirements early.

The PE Exam

The Principles and Practice of Engineering (PE) exam tests competency in a particular engineering discipline.

NCEES describes it as an examination for engineers who have gained a minimum of four years of post-college experience in their chosen engineering discipline.

The PE exam is therefore not simply a harder version of the FE exam.

The two exams serve different stages of the professional pathway.

What Does a PE License Allow You to Do?

A PE license can allow an engineer to take professional responsibility for engineering work.

Depending on state law and the nature of the work, a licensed engineer may sign and seal engineering documents, oversee other engineers, and provide engineering services directly to the public.

Licensure becomes particularly important in fields involving public infrastructure and safety.

Civil and structural engineering are obvious examples.

But you should not assume that every engineer needs a PE license to build a successful career.

Do All Engineers Need a PE License?

No.

This is one of the most important points in this guide.

Licensure requirements depend on the type of work and the state.

Many engineers work successfully without obtaining a PE license. Entry-level engineering jobs generally do not require professional licensure.

The need becomes stronger when an engineer wants to take legal responsibility for certain engineering work or provide services directly to the public.

CareerOneStop’s licensing database confirms that occupational licensing requirements vary by state. It also distinguishes licenses from voluntary professional certifications.

The practical rule is simple.

If you think you may eventually need a PE license, investigate the requirements before choosing your degree program.

That can prevent expensive problems later.

Licensure for Different Engineering Fields

The standard FE-to-experience-to-PE pathway does not apply identically to every engineering occupation.

Civil Engineering: Licensure is highly relevant, especially for engineers whose work involves public infrastructure and professional engineering services.

Mechanical Engineering: Many mechanical engineers work without a PE license. Licensure becomes more relevant when the engineer takes responsibility for regulated engineering work or public-facing projects.

Electrical Engineering: Licensure can be important for engineers responsible for electrical systems and professional services.

Aerospace Engineering: Many aerospace engineers work in industry without a PE license. Their career path can instead focus on technical specialization, research, manufacturing, testing, or defense work.

Computer Hardware Engineering: Computer hardware engineering is less centered on state professional licensure.

BLS describes a bachelor’s degree as the typical entry point and does not present the same standard licensing pathway found in several public-facing engineering disciplines.

Marine Engineering: Licensure is not required for entry-level marine engineers or naval architects. Experienced professionals may pursue PE licensure, particularly when their work requires it. Some maritime roles also involve U.S. Coast Guard credentials.

Nuclear Engineering: Nuclear engineering has additional credentials for certain reactor-operation roles.

The NRC licenses reactor operators and senior reactor operators. Those licenses are separate from state Professional Engineer licenses.

This distinction matters if you are considering nuclear power operations.

Step 5: Choose a Specialization

You do not need to specialize immediately.

Many engineers begin with broad responsibilities and narrow their focus after gaining experience.

Specialization can develop from the projects you work on.

It can also come from an industry you enter.

Consider civil engineering.

One engineer may specialize in structural design. Another may focus on transportation. Another may work in geotechnical engineering.

The same pattern appears elsewhere.

A mechanical engineer might specialize in robotics, automotive systems, manufacturing, or heating and cooling systems.

An electrical engineer might move into power systems, controls, electronics, communications, or renewable energy.

A biomedical engineer might focus on medical devices, rehabilitation technology, imaging, or healthcare systems.

Your specialization should therefore answer two questions:

What technical problems do I enjoy solving?

Where is there enough demand for those skills?

The second question is particularly important for career planning.

At AscendurePro, we recommend looking beyond job titles. We examine skills, industry demand, earning potential, mobility, and long-term career direction when evaluating career choices.

Our career transition roadmap explains how we approach career moves into high-growth industries.

Step 6: Build Career-Ready Engineering Skills

A degree gives you the foundation.

It does not automatically make you highly employable.

The engineering job market rewards people who can apply what they learned.

CAD and Design Software

CAD is important across many engineering disciplines.

Mechanical, civil, aerospace, industrial, and other engineers use design software to create, modify, and evaluate technical designs.

The specific software depends on the discipline.

Focus on becoming capable of producing useful work. Collecting software certificates without practical projects is less valuable.

Data Analysis

Engineering is increasingly data-driven.

Engineers analyze test results, production data, sensor measurements, quality data, and operational information.

Industrial engineers are particularly dependent on data analysis.

However, the skill transfers well across other engineering fields.

Programming

Programming is not mandatory for every engineer.

It is increasingly useful, however.

It can support automation, simulation, data analysis, controls, embedded systems, and engineering software.

Computer hardware engineers, electrical engineers, industrial engineers, and biomedical engineers can all benefit from stronger programming skills.

Simulation

Simulation allows engineers to test ideas before building physical prototypes.

Mechanical, aerospace, civil, electrical, and materials engineers use different forms of simulation.

Learning simulation becomes more valuable when combined with genuine engineering fundamentals.

Technical Communication

Engineering work involves more writing than many students expect.

Engineers prepare reports, specifications, proposals, test results, documentation, and technical recommendations.

They must also explain complex issues to people who may not have an engineering background.

Strong communication can therefore become a career advantage.

Project Management

Engineers increasingly coordinate people, budgets, schedules, suppliers, and technical requirements.

You do not need to become a project manager immediately.

Learning the fundamentals early can prepare you for leadership later.

Problem-Solving

This sounds obvious.

It is also central to engineering.

The strongest engineers do not simply know formulas. They can determine which information matters, identify constraints, evaluate alternatives, and make defensible decisions.

If you are building these skills for a career transition, our guide to in-demand skills to learn now provides a broader skills-development framework.

Step 7: Start Your Engineering Career

Your first engineering job does not need to be your final destination.

In fact, it probably will not be.

New engineers often start under supervision. They gradually handle more difficult designs, analyses, tests, and decisions.

The goal during the early years is not simply to collect a salary.

It is to build evidence of competence.

Look for projects that allow you to develop:

• Technical depth
• Industry knowledge
• Project experience
• Client communication
• Problem-solving ability
• Documentation skills
• Leadership experience

Keep records of meaningful projects: the problem, what you did, tools used, and results.

This makes future applications much stronger.

Step 8: Advance Beyond Entry-Level Engineering

Engineering careers can develop in several directions. You do not have to become a manager. Additionally, you do not have to remain a purely technical specialist.

Senior Engineer

Senior engineers handle more complex work.

They also make more independent decisions and often guide less experienced colleagues.

Technical Specialist

Some engineers prefer technical depth.

They become experts in a narrow area and solve difficult technical problems.

This path can suit people who enjoy engineering more than management.

Project Engineer

Project engineers combine technical responsibilities with project coordination.

They may track schedules, coordinate teams, communicate with clients, and help control project requirements.

Engineering Manager

Engineering managers supervise engineers and coordinate technical teams.

BLS reports a $167,740 median annual wage for architectural and engineering managers in 2024.

That occupation is separate from the 18 engineering careers covered in our main table.

It is worth mentioning because management is a common advancement route.

Research and Development

Engineers with advanced degrees may move deeper into research.

This can involve developing new materials, technologies, products, processes, or scientific applications.

A master’s degree can help with some research roles. A Ph.D. becomes more important for advanced research and academic careers.

Consulting

Experienced engineers can move into consulting.

Consultants use their technical expertise to solve specific problems for clients.

This route can offer greater variety than working on projects for a single employer.

Sales Engineering

Some engineers move into sales engineering.

This is particularly useful for professionals who enjoy explaining technical products and working directly with customers.

The technical background remains valuable.

The work simply changes.

Entrepreneurship

Engineering can also lead to entrepreneurship.

Engineers can establish consulting firms, engineering services companies, product businesses, technology startups, and specialized technical practices.

The technical foundation becomes one part of a broader business skill set.

How Long Does It Take to Become an Engineer?

There is no fixed timeline for becoming an engineer.

For most students, the bachelor’s degree takes about four years of full-time study. That timeline can stretch if you change majors, study part time, repeat courses, or work while completing your degree.

Professional licensure can add several more years. If you plan to become a licensed Professional Engineer (PE), you will generally need relevant work experience after graduation and must satisfy the requirements set by your state licensing board.

NCEES uses four years of post-college engineering experience as a benchmark within its PE exam framework. However, that does not mean every state uses exactly the same requirement.

For someone pursuing PE licensure, a reasonable planning estimate is therefore eight years or more from the start of a bachelor’s degree to full licensure.

It is important not to treat that figure as a universal rule. Many engineers never need or pursue a PE license, particularly those working in roles where the law does not require one. Some states also allow alternative education or experience pathways under certain conditions.

For planning purposes, think of four years for the degree and about four years of professional experience as useful benchmarks. Your actual timeline will depend on your field, career goals, education path, and state requirements.

Can You Become an Engineer Without an Engineering Degree?

Yes, but the answer depends on what you mean by “become an engineer.”

For the traditional engineering occupations tracked by the BLS, a bachelor’s degree is generally the standard entry-level education. Employers may sometimes accept a closely related degree, particularly when the candidate has the right technical skills and experience.

The acceptable background varies by field and employer. Biomedical engineering, for instance, can attract graduates from several engineering disciplines. Computer hardware engineering can likewise overlap with computer engineering and other closely related technical fields.

Professional licensure is a different matter.

If your career goal involves becoming a licensed PE, you need to pay close attention to your state’s education requirements. Some states recognize alternative educational routes, but eligibility depends on the specific rules of the licensing board.

CareerOneStop can help you identify licensing requirements in your state. For an actual licensing decision, however, the relevant state engineering board is the authority you should rely on.

Can You Switch Into Engineering as a Career Changer?

Yes. The difficulty largely depends on where you are starting from.

Someone with a physics degree, for example, may already have many of the mathematics and science foundations needed for certain engineering paths. A professional coming from mathematics, computer science, chemistry, biology, architecture, or another technical field may also have transferable knowledge that shortens the learning curve.

The better starting question is not:

“Which engineering course should I take?”

Ask this instead:

“Which engineering role am I trying to move into?”

Once you have a target role, you can compare its requirements with your current background. You may find that you need formal education, stronger engineering fundamentals, software skills, industry knowledge, practical experience, professional credentials, or evidence of your abilities through a portfolio.

This approach is usually more useful than taking unrelated engineering courses and hoping they eventually lead somewhere.

Our career transition roadmap follows the same basic idea. You start with the target career, then map the skills and experience needed to reach it.

If you are considering a broader career change, our research on career change success rates provides additional context for planning the transition.

How to Choose the Right Engineering Career

Salary is useful, but it should not be the only reason you choose an engineering field.

The engineering occupation with the highest median pay may not offer the type of work, environment, or career path you actually want.

A better approach is to compare several factors before making your decision.

1. Your Academic Strengths

Start with the subjects you naturally enjoy and handle well.

Do you prefer physics and mechanics? Chemistry? Mathematics? Biology? Computers and electronics?

Your answers can help narrow the list, although they should not automatically determine your choice.

2. The Type of Work You Want

Engineering jobs can look very different from one another.

Some engineers spend much of their time designing and modeling. Others work in laboratories, manufacturing plants, construction sites, or other field environments. Some focus heavily on processes, systems, and people rather than designing physical products.

Industrial engineering is a good example. Much of the work involves finding ways to make systems more efficient rather than designing a single physical product.

3. Work Environment

Think about where you would actually enjoy spending your working hours.

Someone who prefers offices and laboratories might find computer hardware, biomedical, materials, or aerospace engineering appealing. Those who enjoy being outdoors or working on physical projects may prefer fields such as civil, mining, marine, agricultural, or environmental engineering.

There are plenty of exceptions, though. The same engineering discipline can involve very different working environments depending on the employer and specific role.

4. Income

When comparing engineering careers, look at median pay rather than focusing on the highest salaries you see advertised.

The median gives you a better sense of what workers in the middle of an occupation earn. Industry also matters because engineers in the same discipline can have very different earnings depending on where they work.

For example, BLS reports a 2024 median wage of $179,190 for computer hardware engineers working in research and development, compared with $155,020 for the occupation overall.

5. Employment Growth

Pay tells only part of the story.

Job growth can give you a sense of where employment opportunities may expand over time. In our dataset, industrial engineering has the highest projected growth at 11 percent, followed by mechanical engineering at 9 percent.

Computer hardware engineering and electrical/electronics engineering are each projected to grow by 7 percent as occupational groups.

Those figures are useful, but growth percentage should always be viewed alongside the size of the occupation.

6. Number of Job Openings

A high growth rate does not automatically mean there will be more jobs available.

A relatively small occupation can grow quickly while still producing fewer openings than a much larger field. That is why it makes sense to consider growth rate, total employment, and annual openings together.

Civil engineering provides a good example. Its projected growth is lower than that of mechanical or industrial engineering, yet BLS projects roughly 23,600 openings each year.

That difference is important. When comparing engineering careers, you are not simply asking which field is growing fastest. You are also asking how many opportunities are likely to exist and whether those opportunities match your goals.

Engineering Is Not One Career

One of the easiest mistakes is to think of engineering as one career.

It is not.

Engineering covers many different fields, and the day-to-day work can vary widely.

A computer hardware engineer might design processors, circuit boards, or other computer components. A civil engineer, by contrast, could spend their time designing bridges, roads, or transportation systems.

Chemical engineers often work on industrial processes. Biomedical engineers may develop medical devices. Petroleum engineers focus on oil and gas extraction, while marine engineers may work on ship propulsion or offshore systems.

Industrial engineers take a different approach. They look at entire production systems and find ways to make them more efficient.

They all have “engineer” in their job title. But the work, skills, industries, and career paths can be very different.

That is why choosing an engineering degree should start with the career itself—not just the degree name.

First, understand what the work actually involves. Then choose the engineering field that fits your interests and strengths.

Frequently Asked Questions

Do I need a bachelor’s degree to become an engineer?

For the engineering occupations covered in this guide, a bachelor’s degree is generally the typical entry-level education.

The specific degree can vary by occupation.

Related engineering degrees may also qualify candidates for some roles.

Do I need an ABET-accredited degree?

Not necessarily for every engineering job.

ABET accreditation becomes particularly important when you are considering professional engineering licensure or employers that specify accredited programs.

Requirements vary by state and occupation.

Check the specific program before enrolling.

What is the FE exam?

The FE exam stands for Fundamentals of Engineering.

NCEES describes it as the first major examination in the typical professional engineering licensure pathway. It is intended mainly for students nearing completion of an undergraduate engineering degree and recent graduates.

What is the PE exam?

The PE exam stands for Principles and Practice of Engineering.

It assesses competency in a specific engineering discipline. NCEES describes it as an exam for engineers with relevant post-college experience.

How many years of experience do I need before the PE exam?

Four years is a common benchmark.

However, licensing rules are established by individual states.

Some jurisdictions have different education and experience combinations.

Check your state board before relying on a general timeline.

Do all engineers need a PE license?

No.

Many engineers work without professional licensure.

The need depends on the type of work, the state, and whether the engineer must take professional responsibility for regulated engineering services.

Which engineering career pays the most?

Among the 18 engineering occupations analyzed here, computer hardware engineering had the highest 2024 median wage at $155,020.

Petroleum engineering followed at $141,280. Aerospace engineering reported $134,830.

These are 2024 BLS median wages, not 2026 salary estimates.

Which engineering career is growing fastest?

Industrial engineering has the highest projected growth in our dataset.

BLS projects 11 percent growth from 2024 to 2034. Mechanical engineering follows at 9 percent.

Can I become an engineer after studying another subject?

Possibly.

Your options depend on your existing education, target engineering occupation, employer requirements, and licensing goals.

Someone with a closely related technical degree may have a shorter transition than someone entering from an unrelated field.

Is engineering a good career?

Engineering can provide strong earnings, technical depth, and multiple advancement routes.

But “good” depends on your goals.

Consider income, job growth, work environment, location, education requirements, and the type of problems you enjoy solving.

The strongest choice is the engineering career that fits both your abilities and your long-term goals.

Conclusion

Becoming an engineer in the United States follows a fairly structured path, but the route can vary depending on the field you choose and whether your career requires professional licensure.

For most aspiring engineers, the journey starts with a strong foundation in mathematics and science, followed by a bachelor’s degree in the relevant engineering discipline. From there, gaining practical experience becomes increasingly important. Internships, co-ops, laboratory work, capstone projects, and entry-level positions can help bridge the gap between what you learn in school and what you will actually do at work.

Licensure is another piece of the puzzle, although it is not required for every engineering role. Where a professional license is necessary, the typical route involves earning an engineering degree, passing the FE exam, gaining the required work experience, and then taking the PE exam. The specific requirements can differ from one state to another.

The more important decision comes before any of that.

Choose the engineering problem you want to solve before choosing the engineering degree.

Someone fascinated by machines and mechanical systems may find mechanical engineering a natural fit. A person more interested in roads, bridges, buildings, and other infrastructure might prefer civil engineering. Those drawn to circuits, electronics, and computer hardware could find electrical, electronics, or computer hardware engineering more rewarding.

The same applies to other fields. Biomedical engineering suits people interested in healthcare and medical technology, while industrial engineering may appeal to those who enjoy improving processes, efficiency, and complex systems.

Job-market conditions should also influence your decision.

Our analysis of BLS data shows substantial differences across the 18 engineering occupations we examined. Computer hardware engineering currently has the highest median pay, while industrial engineering has the strongest projected employment growth.

Those numbers are useful, but they should not make the decision for you. A career that pays well on paper may still be a poor fit if the work does not match your interests, strengths, or long-term goals.

The same thinking applies to career changers. Rather than starting with a degree, begin with the engineering role you want to move into. From there, assess your existing skills, identify the gaps, and work out what education and experience you actually need.

Our Career Transition Roadmap provides a structured framework for planning that process. You can also explore our broader career change research for a deeper look at the factors that influence successful career transitions.

For students, graduates, and professionals comparing engineering options, the most useful question is therefore not simply “How do I become an engineer?”

A better question is “Which engineering career gives me the strongest match between my skills, interests, earning goals, and the future job market?”

Answering that question first can make the rest of the journey much clearer.
