About the role

What You’ll Do

  • Own the mechanical design, thermal analysis and integration of propulsion components and subsystems
  • Resolve design, fit, thermal and integration issues discovered during prototype and early production builds, driving root cause analysis and corrective design actions
  • Create and maintain 3D CAD models and 2D drawings, including GD&T and tolerance stackups
  • Perform thermal analysis using hand calculations, FEA, and test correlation to guide design decisions
  • Define and implement thermal management strategies for motors, inverters, and power electronics (air and/or liquid cooling, heat sinks, TIMs, enclosures, insulation)
  • Perform DFM/DFA trade studies, balancing weight, cost, thermal performance, reliability, and manufacturability
  • Work with suppliers and internal manufacturing partners to assess feasibility, fabrication methods, tolerances, and rapidly resolve build issues
  • Provide hands on support during prototype and early production assembly, integration, and bench testing of propulsion hardware
  • Support test planning, data review, design iteration, translating test results and build feedback into actionable improvements
  • Document designs, design changes, analyses, and test results clearly

What We’re Looking For

  • B.S. Mechanical Engineering, Aerospace Engineering or a related field
  • 1-5 years of experience in mechanical design, thermal engineering, or closely related roles (internships and project experience count)
  • Experience designing mechanical hardware using CAD to manage designs (NX preferred)
  • Strong foundation of thermal analysis methods (FEA, analytical modeling or CFD)
  • Familiarity with GD&T and tolerance stack up analysis
  • Solid understanding of common manufacturing processes
  • Comfortable working on electromechanical systems; exposure to motors, power electronics, or cooling systems is a plus
  • Hands on mindset with interest in building, testing and iterating hardware
  • Strong problem-solving skills and attention to detail
  • Clear communicator who works well on multidisciplinary teams

Nice to Have

  • Experience with propulsion, power electronics packaging, or high-power electromechanical systems
  • Exposure to liquid cooling systems or forced-air thermal design
  • Hands-on experience building or troubleshooting hardware (projects, student teams, UAVs, robotics, racing, etc.)
  • Comfort working in early, ambiguous designs with fast iteration cycles
  • Familiarity with PLM tools (Teamcenter preferred)
