- Drive resolution of real hardware issues discovered during prototype and early production builds.
- Create and maintain 3D CAD models and 2D drawings, including GD&T and tolerance stackups.
- Perform DFM/DFA trade studies, balancing weight, cost, thermal performance, reliability, and manufacturability.
- Work with suppliers and internal teams to assess manufacturing feasibility and refine designs.
- Support hands-on prototype assembly, integration, and test, including debugging and root cause analysis.
- Conduct engineering analysis using a mix of hand calculations and FEA to inform design decisions.
Job Requirements
- B.S. or M.S. in Mechanical Engineering, Aerospace Engineering, or a related field.
- 4+ years of experience in mechanical design of complex systems or equivalent demonstrated capability.
- Proficiency in 3D CAD (NX preferred) and creating production-quality drawings with GD&T.
- Strong understanding of tolerance stack-ups and real-world fit/integration challenges.
- Experience designing for a range of manufacturing processes (machining, sheet metal, additive, etc.).
- Hands-on experience building, testing, and troubleshooting hardware.
- Comfortable working on electromechanical systems (motors, power electronics, rotating machinery, batteries, cooling systems, etc.).
