- Lead competitive benchmarking and cost-performance improvement programs.

- End-to-End Product Development Leadership

- Own the full product lifecycle: concept design prototype validation certification release to manufacturing.
- Oversee development of utility-scale BESS platforms (1-5 MWh containers) and industrial BESS products.
- Drive cell-to-pack development (module structure, pack architecture, thermal pathways, safety features).
- Ensure alignment with standards (UL 9540/9540A, UL 1973, IEC 62933, IEEE, CE, BIS).

- Cross-Functional Engineering Management

- Lead R&D; teams across all functions - Electrical & Power electronics, Mechanical/Structural design, Thermal & Cooling systems, Battery module/pack engineering,



BMS/EMS controls & firmware development, System engineering & safety, Testing & validation.
- Build strong collaboration with Product Management, Operations, Quality, Supply Chain, and Field Engineering teams.

- 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.

- 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).

- 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.

- Leadership & Organizational Development

- Build and mentor a world-class R&D; organization.
- Develop engineering competency frameworks and technical career ladders.
- Establish strong project governance,



development processes, documentation, and design reviews.

Required Qualifications

- M.Tech/PhD in Electrical, Mechanical, Thermal, Power Electronics, Energy Systems, or related fields.

Experience

- 12-20+ years in Energy Storage, Batteries, EV, Renewable R&D;, or Power Electronics.
- Minimum 5-8 years leading multi-disciplinary engineering teams.
- Proven track record of launching Utility-Scale or Industrial BESS products.
- Deep understanding of Cell chemistry, aging, safety, SoC/SoH estimation, Module/pack design, Liquid cooling/air cooling, High-voltage system design (600-1500V), Power electronics & inverter-battery interactions, EMS/BMS firmware & communication protocols (CAN, Modbus, IEC 61850), Fire detection & suppression.
- Knowledge of regulatory standards: UL, IEC, IEEE, IS.

Preferred Skills

- Experience with giga-factory cell supply, cell qualification, and vendor management.
- Experience in cost modeling (cell-to-pack, pack-to-system).
- Solid program management and cross-functional leadership skills.
- Ability to work with global teams and customers.
- Strong analytical, strategic thinking, and communication skills.

KPIs (Key Performance Indicators)

- On-time delivery of product roadmap milestones.
