Job Description

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-Quick)
- 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.
