Senior Engineer - Design COE EV

Responsibilities & Key Deliverables

Job Summary

As a Lead Engineer in Electrical Design & Development for High Voltage (HV) Battery Packs, you will be responsible for the end-to-end design, integration, and validation of electrical systems within advanced energy storage solutions. This role is critical in the development of safe, efficient, and high-performance battery packs for electric vehicles (EVs), hybrid systems, and stationary energy storage applications. You will lead cross-functional efforts to architect electrical systems, select components, ensure compliance with safety and regulatory standards, and drive innovation in battery management and power distribution. Your expertise will contribute to the development of scalable and manufacturable solutions that meet stringent performance, thermal, and reliability requirements. 

Key Responsibilities: System Architecture & Design • Lead the electrical design of HV battery packs including cell interconnects, busbars, contactors, fuses, and insulation systems. • Develop and validate schematics, wiring harnesses, and PCB layouts for Battery Management Systems (BMS), current sensors, and voltage monitoring circuits. • Define system-level electrical architecture including HV and LV interfaces, isolation strategies, and grounding schemes. Component Selection & Integration • Select and integrate key components such as relays, connectors, current sensors, pre-charge circuits, and HV disconnects. • Collaborate with thermal and mechanical teams to ensure optimal packaging and cooling of electrical components. Safety & Compliance • Ensure compliance with automotive and industrial safety standards (e.g., ISO 26262, IEC 60664, UL 2580, ASIL). • Conduct DFMEA and risk assessments for electrical systems and components. • Implement robust insulation coordination and creepage/clearance analysis for HV systems. Testing & Validation • Develop and execute electrical validation plans including HV insulation testing, continuity checks, and fault injection. • Support EMC/EMI testing and mitigation strategies. • Analyse test data and lead root cause investigations for electrical failures. Project Leadership & Collaboration Coordinate with BMS software, mechanical, and manufacturing teams to ensure seamless integration and production readiness. • Interface with suppliers to define requirements and resolve technical issues. • Lead design reviews and mentor junior engineers in HV system design best practices.
