- 3+ years of experience in mechanical design, packaging, and thermal management for aerospace or ruggedized electronic systems
- Proven ability to deliver mechanical systems from concept through qualification and flight
- Proficiency with CAD (SolidWorks, NX, or equivalent) and analysis tools for structural and thermal performance
- Hands-on experience building, testing, and debugging hardware in a lab environment
- Strong communication skills and comfort working cross-functionally in a fast-paced, rapidly iterating team environment
Nice To Haves But Not Required
