3. NPI & Prototype Development

- Lead NPI activities for new BESS products.
- Coordinate with R&D;, Design, Quality, Production, SCM and Projects teams.
- Conduct process validation,



pilot builds, FAI and production trials.
- Drive smooth transition from engineering prototype to commercial production.
- Identify process risks and establish mitigation plans before SOP.

4. Automation & Manufacturing Excellence

- Identify opportunities for automation, robotics, laser welding, testing and digital manufacturing.
- Drive OEE, FPY, cycle-time, throughput and productivity improvements.
- Implement Lean Manufacturing, Kaizen, Six Sigma and waste reduction initiatives.
- Optimize manpower, equipment utilization and line balancing.

5. Quality & Process Control

- Lead PFMEA, Control Plan, Process Flow, SOP and work instruction development.
- Identify critical-to-quality and critical-to-process parameters.
- Drive root-cause analysis using 8D, 5 Why, Fishbone, SPC and DOE.
- Work closely with Quality to reduce defects, rework and customer complaints.
- Ensure compliance with applicable BESS, battery and electrical safety standards.

6. Cost & Commercial Engineering

- Drive process-cost reduction through:
- Cycle-time reduction
- Manpower optimization
- Automation
- Yield improvement
- Material utilization
- Tooling optimization




- Evaluate CAPEX and OPEX requirements for new manufacturing lines.
- Support vendor evaluation and technical-commercial negotiations for process equipment and automation.

7. Team Leadership
