Senior Mechanical Design Engineer [Propulsion]

The role

You will design, analyze, and integrate mechanical and thermal systems for high-power hybrid-electric propulsion. This includes working on motors, generators, inverters, turbines, and supporting structures.

What you will do

• Lead design and analysis of rotating machinery subsystems
• Drive resolution of real hardware issues during prototype and early production builds
• Mentor and provide technical guidance to mid-level and junior engineers
• Contribute to planning and technical strategy for the propulsion team
• Create and maintain 3D CAD models and 2D drawings
• Perform DFM/DFA trade studies
• Work with suppliers and internal teams to assess manufacturing feasibility
• Support hands-on prototype assembly, integration, and test
• Conduct engineering analysis using hand calculations and FEA
• Implement and refine thermal management strategies

Required qualifications

• B.S. or M.S. in Mechanical Engineering, Aerospace Engineering, or a related field
• Experience with high speed rotating machinery and associated challenges
• 5+ min years of experience in mechanical design of complex systems
• Demonstrated experience owning and delivering on a critical assembly or subsystem from concept through production
• Proficiency in 3D CAD
• 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
• Hands-on experience building, testing, and troubleshooting hardware
• Comfortable working on electromechanical systems
• Demonstrated ability to debug issues, perform root cause analysis, and drive corrective actions
• Experience working in fast-paced, iterative hardware development environments

Nice to have

• Experience with propulsion systems or electromechanical systems
• Background in thermal management of high-power systems
• Experience with rotor dynamics or vibration analysis tools
• Experience performing thermal and/or structural analysis
• Experience supporting prototype builds and early production environments
• Familiarity with PLM systems
• Background in aerospace, automotive (EV/powertrain), robotics, or similar high-performance hardware industries
