Job Description

Group Lead -Mechanical Design

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.

2. Product Engineering & Execution

  • 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
  • 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.

4. Thermal, Reliability & Environmental Validation

  • Own thermal validation plans (steady-state, transient, derating analysis).
  • Drive CFD simulations and correlation with physical testing.
  • Ensure compliance with:
    • Temperature rise limits
    • Noise & vibration requirements
    • Environmental tests (IP, salt mist, humidity, dust)

5. Manufacturing, Quality & Field Support

  • Support NPI, pilot builds, and production ramp-up.
  • Drive mechanical failure analysis, field issue RCA, and corrective actions.
  • Work with supply chain on:
    • Vendor qualification
    • Localization & alternate sourcing
    • Tooling and fixture development
  • Improve yield, assembly time, and cost in production.

6. Cross-Functional & Business Engagement

  • Work closely with:
    • Electrical & Power Electronics Engineering
    • Systems & Controls
    • Manufacturing, Quality, and Supply Chain
  • Act as mechanical authority in customer and certification discussions.
  • Support pre-sales and customization efforts.
  • Build and mentor a high-performance mechanical engineering organization.

 

Education

  • BE / BTech in Mechanical Engineering
  • MTech / MS preferred

Experience

  • 15+ years in mechanical engineering for power electronics or industrial products
  • Proven leadership in high-power, thermally constrained systems
  • Experience from concept to mass production environments
  • Mechanical Design, Thermal Engineering, Packaging & Validation
  • Should have handled team of mechanical design 
  • Should have experience in Solar Inverter & PCS ,BESS Container Manufacturers

EV Charger OEMs and  Industrial Power Electronics Companies.
