Lead Mechanical Design Engineer – Power Converters
Role Summary
As a Lead Mechanical Design Engineer, you will own the
end-to-end mechanical design and industrialization
of high-power converter products (40 kW rectifier modules to MW-scale central inverters). The role requires deep expertise in
automotive-grade design processes, reliability engineering, and global compliance standards
, ensuring scalable, cost-optimized, and production-ready solutions.

Key Responsibilities
- Product Architecture & Platform Strategy
- Define scalable mechanical platforms for:
- Rectifier modules (30–60 kW class)
- Power stacks and converter cabinets
- MW-scale central inverter systems
- Drive platform reuse, modularization, and standardization
- Align with global product roadmaps and customer-specific adaptations
- Thermal & Cooling Engineering (Critical for Tier-1)
- Design high-efficiency cooling systems:
- Forced air cooling (ducted, sealed systems)
- Liquid cooling (cold plates, manifolds, CDU integration)
- Perform Multiphysics simulations using:
- ANSYS
- Icepack
- FloTHERM




- Optimize junction temperatures for IGBT / SiC devices, magnetics, and capacitors
- Ensure derating strategy and thermal robustness under worst-case conditions
- Mechanical Design & CAD Ownership
- Lead detailed design using:
- Creo
- Siemens NX
- SolidWorks
- Develop:
- 3D CAD models, assemblies, and 2D drawings
- GD&T;, tolerance stack-ups, and design release packages
- Manage BOM and interface with PLM systems
- Design for Excellence (DFX) – Tier-1 Focus
- Drive:
- DFM (Manufacturability)
- DFA (Assembly)
- DFC (Cost optimization)
- DFS (Serviceability)
- Collaborate with global suppliers and contract manufacturers
- Support sourcing strategy and vendor development
- Reliability, Durability & Validation
- Design for automotive/industrial reliability targets (10–15+ years life)
- Conduct and support:
- HALT / HASS
- Thermal cycling
- Vibration & mechanical shock tests
- IP ingress protection validation
