Lead Electrical Design Battery Pack

Role & responsibilities

Position Summary

Lead electrical design and development of HV battery packs for EVs and energy storage systems: electrical architecture, wiring harness design, component selection, busbar design, integration and virtual validation, from concept to SOP. The role reports to the Lead Battery Pack R&D.

Experience framing: automotive electrical design and product development, with a core portion in EV battery pack, wiring harness, power distribution, BMS integration or automotive electrical systems, and experience leading an electrical design team.

3. Must Have Skills

• HV battery pack electrical architecture and design
• Wiring harness design and development
• Battery pack busbar design and material selection
• Electrical CAD tools (CATIA Electrical, Siemens Capital Harness, Zuken E3, SolidWorks Electrical or AutoCAD Electrical)
• Leading electrical design teams

4. Good To Have Skills

• HV and LV component integration
• Connector, terminal and cable sizing and routing
• Automotive electrical distribution systems
• Ansys
• DFM and DFA
• DVP&R
• APQP, DFMEA and engineering change management
• Root cause analysis
• Harness manufacturing, crimping, termination and busbar fabrication processes
• High voltage safety systems
• EMC/EMI design and validation
• AIS 156, AIS 038 and related EV standards
• BMS integration
• Power distribution and protection systems
• Supplier development
• Cost optimization and VAVE

5. Roles and Responsibilities

• Lead and manage the Electrical Design team; drive concept-to-SOP electrical design; define standards and guidelines; plan resources and manage performance.
• Define pack electrical architecture, distribution strategy and interface requirements; design HV and LV circuits.
• Support integration of cells, modules, BMS, current sensors, contactors, fuses, relays, pre-charge circuits, HVIL and protection devices.
• Lead wiring harness design: architecture, cable sizing, routing, protection, retention, drawings, connector interfaces and manufacturing documentation; ensure vibration, temperature, ingress, EMC and durability compliance.
• Lead selection and validation of connectors, terminals, cables, fuses, relays, contactors, sensors and HV components; support supplier assessment; drive standardization and cost optimization.
• Lead busbar design: materials, sizing, current capability, thermal performance, insulation and joining.
• Review electrical schematics, layouts and harness drawings; support Ansys analysis; ensure design data integrity.
• Drive DFM and DFA, prototype builds, pilot production and SOP readiness.
• Support DVP&R and electrical, thermal, vibration and EMC validation; apply APQP and DFMEA; analyze failures and drive corrective actions.
• Coordinate with Battery Systems, Mechanical Design, BMS, Validation, Manufacturing, Quality, Procurement and Vehicle Integration; engage harness vendors and connector manufacturers.
