- Build strong collaboration with Product Management, Operations, Quality, Supply Chain, and Field Engineering teams.
- 1. Innovation, IP, and Advanced Engineering

- File patents for thermal management, module designs, battery controls, fire mitigation systems, etc.
- Drive cost reduction through advanced materials, liquid cooling, optimized pack designs, and architecture simplification.
- Establish partnerships with cell manufacturers, universities, and research institutes.
- 1. Testing, Validation & Certification

- Set up and manage R&D; labs: cell/module test labs, environmental chambers, fire testing, inverter-battery integration labs.
- Define test plans for performance, reliability, safety, and life-cycle validation.
- Oversee third-party certification and large-scale fire testing (9540A).
- 1. Manufacturing & Industrialization Support

- Guide Design for Manufacturing (DFM), Design for Assembly (DFA), and design transfer.
- Review production processes (module assembly, pack assembly, wiring harness, leak testing).
- Support supplier qualification for cells, cooling components, electronics, and safety equipment.
- 1.



Leadership & Organizational Development
