- High Voltage EV Chargers (AC, DC Fast, 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.

2. 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.

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.
- Prepare and maintain:

- 3D models & 2D drawings
- BOMs & assembly instructions
- Installation and service manuals

- Ensure proper revision and change management.

4. Thermal, Reliability & Environmental Validation

- Own thermal validation plans (steady-state, transient, derating analysis).
- Coordinate with CFD team - Given input simulations and correlation with physical testing.
- Select heatsinks, cooling methods that are manufactural
- Ensure compliance with:
- Temperature rise limits
- Noise & vibration requirements
- Environmental tests (IP, salt mist, humidity, dust)

- Perform/Coordinate structural analysis for:

- - Static & agile loads
- Transportation & seismic conditions

- Ensure compliance with wind, seismic, and shock/vibration requirements.
- Design for safe lifting, handling, and installation.

5. Integration with Electrical & Control Systems

- Coordinate with electrical and control teams on:
- Component placement & clearances
- Cable routing and bending radius
- EMI shielding & segregation

- Ensure creepage, clearance,



and safety requirements are mechanically supported.

6. 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.

7. Cross-Functional & Business Engagement

- Work closely with:
- Electrical & Power Electronics Engineering
- CFD/Thermal, Structural Analysis teams
- 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.
