Mechanical Engineer Job Description (2026): Duties, Skills and Salary
A mechanical engineer designs and tests physical products and systems: parts, assemblies, machines or mechanisms that have to work reliably under real-world stress, heat, vibration or wear. They model designs in CAD, run or interpret analysis, build and test prototypes, and work with manufacturing to make sure a design can actually be built at the tolerances it needs.
Mechanical engineers work in industries from automotive and aerospace to consumer products and industrial equipment, so the specific tools and materials vary a lot, but the core loop of design, analyze, test and revise stays the same. The strongest engineers think about manufacturability and cost early, not just after a design is finalized.

About [Company]
[Two or three sentences on what your company does, who it serves and why this team matters now.]
About the role
[Company] is hiring a mechanical engineer to design and test [product/system]. You'll build CAD models in [SolidWorks / CATIA / Creo], run or review analysis, and work with [manufacturing / suppliers] to get designs from concept to production.
What you'll do
- Design parts and assemblies in [SolidWorks / CATIA / Creo] that meet functional and manufacturing requirements.
- Run or interpret FEA, tolerance and thermal analysis to validate designs before building.
- Build and test prototypes, and iterate designs based on results.
- Create and maintain drawings, BOMs and specifications for manufacturing.
- Work with suppliers and manufacturing to resolve design-for-manufacturing issues.
- Troubleshoot field or production issues and propose design fixes.
- Document design decisions, test results and changes for future reference.
What you'll bring
- [X]+ years of mechanical design or engineering experience.
- Proficiency with a 3D CAD tool such as SolidWorks, CATIA or Creo.
- Understanding of material properties, tolerancing (GD&T) and manufacturing processes.
- Experience with analysis tools (FEA, CFD) or working closely with analysts who run them.
- Comfortable building and testing physical prototypes, not just working on screen.
- Clear technical documentation and communication with cross-functional teams.
Nice to have
- Experience with [domain, e.g. automotive, aerospace, medical devices or consumer electronics].
- Familiarity with DFM/DFA and working directly with contract manufacturers.
- Scripting for automation (MATLAB, Python) of analysis or data processing.
- Exposure to regulatory or industry standards relevant to [domain].
What we offer
- [Pay range: e.g. $X–$Y base salary, plus bonus or equity if offered]
- [Relocation assistance, professional licensure (PE) support, prototyping budget]
- [Health cover, retirement or pension plan, paid time off, parental leave]
- [Work authorization: whether you can sponsor a visa or hire through an employer of record]
[Our process: a recruiter call, a technical interview on design and analysis fundamentals, a design exercise or portfolio review, and a meeting with the engineering team.]
[Your equal opportunity statement, and how candidates can ask for adjustments during the process]
Put the pay range in the ad. Several US states, including California, Colorado, New York and Washington, require it in job postings, and the EU Pay Transparency Directive gives applicants the right to know the starting pay or its range before the interview.
Mechanical Engineer duties by seniority
What the job usually looks like at each level. Pitch the ad at one level and say which in the title.
Junior
- Designs individual parts and simple assemblies under a senior engineer's review.
- Runs basic analysis and documents results with guidance.
- Supports prototype builds and testing.
Mid-level
- Owns design of subsystems or assemblies from concept through production release.
- Selects and runs the right analysis for a design without being told which to use.
- Works directly with manufacturing and suppliers to resolve design issues.
Senior
- Leads design for complex systems and sets technical direction for a product line.
- Reviews other engineers' designs and analysis for soundness and manufacturability.
- Mentors engineers and represents engineering in cross-functional product decisions.
Mechanical Engineer career path
- Junior Mechanical Engineer
- Mechanical Engineer
- Senior Mechanical Engineer
- Principal Engineer or Engineering Manager
Mechanical engineer almost always starts with a mechanical engineering degree, sometimes alongside an internship or co-op that gives hands-on design experience. From here people move into specialized design or analysis roles, project management, or engineering management, and some pursue a PE license for certain industries.

Mechanical Engineer job description FAQ
What does a mechanical engineer do?
Designs and tests physical parts, assemblies or systems, using CAD software, engineering analysis and physical prototypes to make sure a design works reliably and can actually be manufactured.
What skills should a mechanical engineer job description require?
Proficiency with a 3D CAD tool, understanding of materials and tolerancing (GD&T), and experience with analysis such as FEA. Specify the industry and the CAD tool used, since both affect how directly a candidate's experience transfers.
Does a mechanical engineer need a professional license?
Not usually for industry roles designing consumer or commercial products. A PE license matters more for engineers who sign off on public-facing work like infrastructure or construction, so only require it if the role actually needs it.
