Job Description

Lead-Mechanical Engineering | Power Electronics Product & Systems

Role

Provide end-to-end leadership for mechanical engineering and thermal systems 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 (Solar Inverters, BESS/PCS, EV Chargers, Electrolysers, and Industrial Power Electronics products.)

Key Responsibilities

1. Mechanical & Thermal Architecture Leadership

• Define mechanical system architecture for:
  • Solar Inverters (String & Central)
  • BESS / PCS Cabinets & Containers
  • EV Chargers (AC, DC Fast, Ultra-Fast)
  • Electrolyser Power Supply Systems and other 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.
• Lead teams covering:
  • Mechanical Design & CAD
  • Thermal & CFD Engineering
  • Structural & Sheet-Metal Design
  • Packaging & Industrial Design
• Establish 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.

3. Product Development Lifecycle Ownership

• Own mechanical development across:
  • Requirements → Concept → Detailed Design → Prototype → Validation → Production
• Drive Design for Manufacturability (DFM), Design for Assembly (DFA), and Design for Serviceability (DFS).
