About the Role
You will own the mechanical, thermal-mechanical, and enclosure design of rack-mounted AI inference systems. You will create designs, models, drawings, BOMs, and tolerance analyses; lead thermal and structural simulations; manage manufacturing partners; improve manufacturability and cost; develop fixtures and packaging; and oversee validation, risks, ECOs, and production escalations.
Requirements
- BS/MS in Mechanical Engineering
- 7+ years designing electromechanical and enclosure hardware for high-performance electronic systems
- Experience across the NPI lifecycle from concept through volume production
- Expertise in 3D CAD using SolidWorks and/or Creo
- Experience with detailed drawings, GD&T, tolerance stack-up analysis, and structural and thermal simulation
- Experience with rack-mount or high-density electronic packaging
- Experience selecting, qualifying, and managing custom-part suppliers and contract manufacturers through EVT, DVT, and pilot phases
- Experience applying DFM, DFA, and FMEA in high-volume or high-complexity production
- Ability to write mechanical specifications and communicate trade-offs across technical and operations teams
Responsibilities
- Own mechanical design for enclosures, chassis, and carrier-board integration for rack-mount inference systems
- Create spatial studies, detailed designs, solid models, drawings, BOMs, and tolerance stack-up analyses
- Lead thermal-mechanical and structural design and simulation for high-TDP ASIC platforms
- Partner with electrical and thermal teams to meet air- and liquid-cooled performance targets
- Lead engagement with contract manufacturers, ODMs, and custom-part fabricators through production ramp
- Conduct DFM, DFA, and DFMEA reviews to reduce cost and improve design robustness
- Develop and qualify electromechanical assembly and test fixtures
- Own product packaging design, transit qualification, and implementation
- Create mechanical test plans and support EMC/EMI shielding and regulatory needs
- Manage mechanical risks, ECOs, and technical escalations
Benefits
