Tech Lead -Mechanical Design | Power Electronics Product & Systems (P11b)
Role
Provide end-to-end leadership for mechanical engineering of power electronics products and integrated systems, ensuring robust mechanical architecture, effective thermal management, environmental protection, manufacturability, and lifecycle reliability across high-power, high-density electrical platforms (AC-DC/DC-DC Converters, EV Chargers and Industrial Power Electronics products.)

Key Responsibilities
- Mechanical & Thermal Architecture Leadership
- Define mechanical system architecture for:
- High Voltage EV Chargers (AC, DC Quick, Ultra-Fast)
- Solar Inverters (String & Central)
- Automotive On-board Chargers/ Drivetrain inverter /MCU enclosure design
- industrial PE products
- Own thermal management strategy:
- Natural & forced air cooling
- Liquid cooling (cold plate, immersion where applicable)
- Heat exchanger and airflow optimization
- Define enclosure concepts, IP ratings, corrosion protection, and seismic/wind load compliance.
- Product Engineering & Execution
- Lead teams covering:




- Mechanical Design & CAD
- Packaging & Industrial Design
- Thermal & CFD Engineering
- Structural & Sheet-Metal Design
- Understand and implement mechanical design standards, guidelines, and review processes.
- Drive power density improvements through optimized packaging.
- Ensure design trade-offs between cost, thermal performance, reliability, acoustics, and serviceability.
- Product Development Lifecycle Ownership
- Own mechanical development across:
- Requirements → Concept → Detailed Design → Prototype → Validation → Production
- Implement V-Model / Stage-Gate / APQP processes.
- Drive Design for Manufacturability (DFM), Design for Assembly (DFA), and Design for Serviceability (DFS).
- Lead value engineering and cost-reduction initiatives.
- Prepare and maintain:
- 3D models & 2D drawings
- BOMs & assembly instructions
- Installation and service manuals
- Ensure proper revision and change man
