How to become a mechanical engineer

Why mechatronics graduates often land here

The BLS does not maintain a "mechatronics engineer" SOC code, which leaves the mechatronics-graduate labor market distributed across four BLS classifications: Mechanical Engineers (17-2141), Electrical Engineers (17-2071), Electronics Engineers (17-2072), and Engineers All Other (17-2199, which catches robotics and controls engineers).

Mechanical Engineers (17-2141) is the largest of those classifications by employment (293,100 jobs) and the most common landing role for ABET-EAC mechatronics graduates whose work emphasizes mechanical design with integrated sensors and actuators — robotics chassis design, automated machinery engineering, EV powertrain mechanical work, surgical-robotics mechanical design, semiconductor manufacturing equipment design.

Hiring managers in these roles routinely interview both mechanical-engineering and mechatronics-engineering graduates against the same job description. The mechatronics graduate brings deeper electronics and controls fluency; the traditional ME brings deeper thermodynamics, fluid mechanics, and pure mechanical-design depth. Either can do the job at most US employers; the choice between candidates usually comes down to internship/co-op portfolio and culture fit.

What mechanical engineers actually do

The work splits into rough categories. Most engineers spend their careers in one or two of these:

• Design engineering. CAD-driven design of mechanical components, assemblies, and systems. Daily tools: SolidWorks, NX, CATIA, Creo Parametric, Inventor. Design includes part design, GD&T tolerancing, design for manufacturability (DFM), and assembly engineering.
• Analysis / simulation engineering. Finite-element analysis (FEA) for structural integrity, computational fluid dynamics (CFD) for thermal and flow problems, multi-body dynamics simulation. Tools: ANSYS, Abaqus, Siemens Simcenter, COMSOL Multiphysics.
• Manufacturing engineering. Designing production processes, tooling, fixtures, and lines that make the products mechanical designers spec. Heavy interaction with machine tools, fixturing, robotic cells, and automated equipment — the natural landing zone for mechatronics graduates.
• Test engineering. Designing and running dynamometer tests, vibration tests, thermal cycles, environmental qualification, and reliability testing. Common at automotive OEMs and aerospace primes.
• Product engineering / sustaining engineering. Owning a product line through its production life, handling design changes, supplier issues, field failures, and continuous-improvement projects.
• R&D engineering. Working on technology that does not yet exist at production scale — typically at national labs, large company R&D centers, or specialized R&D consultancies.
• Field / applications engineering. Customer-facing engineering at component suppliers or OEMs — recommending designs, debugging customer applications, sometimes selling.

How to become a mechanical engineer: step-by-step

Step 1 — Earn an ABET-EAC accredited BS (years 1-4)

ABET-EAC accreditation is the prerequisite for clean PE licensure eligibility in most US states and is preferred by most large engineering employers. The accredited options that prepare you for ME-titled roles:

• BS in Mechanical Engineering. Traditional path. About 350 ABET-EAC accredited programs in the US.
• BS in Mechatronics Engineering. ABET-EAC accredited mechatronics programs are rarer (a handful in the US — see our bachelor's in mechatronics guide), but graduates qualify for the same ME-titled roles and have a stronger electrical/controls foundation.
• BS in Engineering with Mechatronics concentration (e.g., NC State / UNCA joint program). ABET-EAC; covers ME plus mechatronics-specific electives.
• Co-op-required programs — Drexel, Northeastern, Cincinnati, Kettering, RIT. Add 12-18 months to graduation but include paid full-time engineering work, which transforms early-career compensation.

Step 2 — Internship or co-op (summers, year 2-3)

Most US ME hiring at large employers is heavily driven by internship-to-full-time conversion. Securing an internship by the summer after sophomore year, and ideally another after junior year, dramatically widens your full-time options.

Step 3 — Take the FE exam (senior year)

The Fundamentals of Engineering (FE) exam is the first step toward PE licensure. NCEES offers a discipline-specific FE Mechanical exam. Pass rates for first-time takers from EAC-accredited programs run roughly 70-75%. Most candidates spend 80-120 hours of dedicated review during the senior year. See our FE exam guide.

Step 4 — Land the first engineering role (year 4)

Starting salaries for ABET-EAC mechanical-engineering BS graduates run typically $70K-$90K base in mid-size US metros, with top-tier employers (SpaceX, Apple, Tesla, top defense primes) starting at $100K+ in expensive metros. Big-3 oil-and-gas operators pay especially aggressively for mechanical-engineering hires going to Houston.

Step 5 — Accumulate qualifying experience for PE (years 4-8)

Work under a licensed PE during your first 4-5 years. Document the engineering work in detail — the state board will eventually want to see specific projects and your responsibilities on them. Most large engineering firms have formal mentorship pairings that handle this; smaller employers may require more proactive documentation on your part.

Step 6 — Take the PE exam (year 4-5+)

Most candidates take the PE around year 4-5 of professional experience. NCEES offers a PE Mechanical exam in three sub-disciplines: Thermal and Fluid Systems, Machine Design and Materials, HVAC and Refrigeration. Most mechatronics-leaning MEs take the Machine Design and Materials variant.

The FE → PE pathway in detail

The Professional Engineer license is granted state-by-state, but NCEES maintains the standardized exams and a model framework that most state boards follow. The pathway:

1. Graduate from an ABET-EAC accredited BS (most states). Some states accept ABET-ETAC graduates for PE with additional qualifying experience; NCEES maintains a state-by-state matrix.
2. Pass the FE exam. 6-hour computer-based exam at Pearson VUE. Discipline-specific (FE Mechanical for most ME path candidates).
3. Earn Engineer-in-Training (EIT) status from the state board after passing the FE.
4. Accumulate 4 years of qualifying engineering experience under the supervision of a licensed PE. Documentation matters — engineering boards want specific projects and responsibilities.
5. Submit the state board application with transcripts, FE results, references from PEs, and the experience record.
6. Pass the PE Mechanical exam in your chosen sub-discipline.
7. Receive your state PE license. Maintain via continuing education (varies by state).

For mechatronics-leaning engineers whose work emphasizes integrated control systems, the PE Control Systems exam (administered as a separate PE discipline rather than under PE Mechanical) is sometimes a better fit. See our full PE licensure guide.

Skills checklist

CAD and engineering software (table stakes)

• Solid working competence in at least one major CAD: SolidWorks, NX (Siemens), CATIA (Dassault), Creo Parametric (PTC), Inventor (Autodesk).
• FEA tool exposure: ANSYS Mechanical, Abaqus, Siemens Simcenter, or CAD-integrated FEA (SolidWorks Simulation).
• CFD basic exposure if applicable to your specialty (ANSYS Fluent, Star-CCM+, OpenFOAM).
• MATLAB / Simulink for system-level analysis and controls work.
• Python for scripting and data analysis.

Mechanical fundamentals

• Statics, dynamics, mechanics of materials, vibrations.
• Thermodynamics, fluid mechanics, heat transfer (less common in mechatronics curricula; a gap to close).
• Machine design — fasteners, bearings, gears, shafts, couplings — at hands-on selection depth.
• GD&T (Geometric Dimensioning and Tolerancing) per ASME Y14.5.
• Materials selection: steels, aluminum alloys, plastics, composites.
• Manufacturing processes: machining, sheet-metal forming, injection molding, additive manufacturing.

For mechatronics-leaning ME roles

• Sensors and actuators selection at design depth.
• Motion-control system architecture — servo vs stepper vs BLDC, drive sizing, motion-profile design.
• Embedded-systems fluency — at minimum reading Arduino-style C/C++; at best comfortable with STM32 or NXP microcontroller development.
• PLC awareness — enough to talk to controls engineers in their language.
• Vision-system fundamentals.

Professional skills

• Engineering writing: design reviews, FMEA documents, test reports, change-orders. Engineers who write clearly get promoted faster.
• Project management basics. Stage-gate processes, milestone tracking, working with PMs.
• Cross-functional communication — with manufacturing engineers, controls engineers, suppliers, customers, executives. Each audience requires a different level of technical depth.
• Ethics and engineering judgment. The NSPE Code of Ethics is the canonical reference; PE candidates are tested on it.

Career growth and pay anchors

1. Engineer I (entry, 0-2 yrs): $70K–$95K base. Highest end: SpaceX, Apple, Tesla, top defense primes in expensive metros.
2. Engineer II (2-5 yrs): $85K–$120K base.
3. Senior Engineer (5-10 yrs): $105K–$145K base.
4. Lead / Staff Engineer (10-15 yrs): $125K–$175K base. Inflection point — choose between management track or technical track.
5. Principal Engineer or Engineering Manager (15+ yrs): $150K–$220K+ base. Plus bonus and stock at large companies.
6. Director / VP of Engineering: $200K–$350K+ total compensation at most US employers; much higher at top tech and defense companies.
7. Senior IC tracks at top tech (Senior Staff, Distinguished, Fellow at Apple, Google, Meta) — total compensation regularly $400K-$1M+, but those roles require unusual depth and reputation.

Job market outlook

BLS projects 9% employment growth for SOC 17-2141 from 2024 to 2034 — "much faster than the average for all occupations." Approximately 19,700 openings are projected each year on average, combining replacement demand with new role creation.

Five structural tailwinds through 2030:

• EV and battery manufacturing buildout. Roughly 30 announced US battery plants are coming online through 2028, plus the ramp at Tesla, Ford EV, Rivian, GM Ultium, Stellantis. Each plant employs hundreds of MEs in product, manufacturing, and sustaining engineering.
• CHIPS Act semiconductor capacity expansion. Intel Ohio, TSMC Arizona, Samsung Texas, Micron New York employ thousands of MEs in equipment and facility engineering.
• Aerospace and defense modernization. Hypersonics, space launch (SpaceX, Blue Origin, Rocket Lab, ULA), uncrewed systems, the F-35 sustainment cycle — all driving sustained ME hiring.
• Surgical robotics installed-base growth. Intuitive Surgical da Vinci installed base, Stryker Mako, and emerging entrants drive continuous ME hiring in medical-robotics engineering.
• Reshoring and Industry 4.0. Companies pulling production back to the US plus the Industry 4.0 / IIoT investment wave is generating significant ME demand in manufacturing engineering.

Mechanical engineer vs other engineer roles

Pitfalls and things to know

• Non-ABET engineering degrees limit options. Some smaller schools market "engineering" BS programs that are not ABET-EAC accredited. Avoid these — they close off the PE pathway and filter you out of many large-employer hiring funnels.
• Internships matter more than GPA at most US engineering employers. Two solid internships beat a 4.0 with no work experience.
• The thermodynamics and fluid-mechanics gap is real for mechatronics graduates. If you graduate from an ABET-EAC mechatronics program and want to compete for HVAC, energy, or aerospace propulsion roles, plan to fill in the thermal-systems and CFD gaps via electives or a master's.
• Oil-and-gas pay is highest but volatile. The $195K+ median in O&G reflects commodity-cycle volatility — pay drops sharply during downturns. The premium is real, but factor in cycle risk.
• The "engineering manager track" is not for everyone. Many strong engineers force themselves into management because that's where the title and compensation gain seemed to be. Many top tech companies (Apple, Google, Meta, etc.) now have IC tracks that pay comparably to management — research before committing.
