- Support testing in HV labs for switching performance, efficiency mapping, isolation testing, EMC, and environmental validation.
- Analyze failures (root cause analysis) and implement corrective actions.
5. Standards, Safety & Compliance
- Ensure hardware meets relevant automotive standards:
- ISO 26262 (functional safety)
- ISO 21448 (SOTIF where applicable)
- LV123 / LV148 / ECE R100 for HV systems
- EMC requirements per CISPR 25, ISO 7637, ISO 11452
- Participate in FMEA/DFMEA, safety goals allocation, and hardware safety mechanism definition.
6. Collaboration & Technical Leadership
- Work closely with cross-functional teams (E-Motor, Power Electronics, Mechanical, Thermal, Software, Control).
- Guide junior engineers on HV hardware design.
- Collaborate with suppliers and evaluate their technical proposals and component capabilities.
- Provide design reviews, documentation, and technical reports.
Requirements Required
- Bachelor's or Master's degree in Electrical Engineering, Power Electronics, Mechatronics, or related fields.
- 7+ years of experience designing high-voltage power electronics hardware for automotive or industrial e-motor drives.
- Deep knowledge of:
- Power semiconductors (IGBT, SiC MOSFET)
- HV insulation design and creepage/clearance rules
- Switching power converters
- Gate driver design
- EMI/EMC mitigation techniques
- Strong hands-on experience in schematic design, PCB layout for HV systems, and prototype debugging.
