• Lead end-to-end testing and integration of power electronics with powertrain and charging ecosystem components
• Oversee complex PCB design for high-reliability, high-performance applications per IPC standards
• Conduct DFMEA, thermal analysis, worst-case circuit analysis, and validation testing on HV systems
• Architect test benches and provide hands-on support for board, component, and vehicle-level bring-up
• Collaborate cross-functionally to troubleshoot electrical and EMI issues; engage with suppliers on component selection

What they're looking for

• High-power electronics design and testing (100kW+ to MW scale)
• Power conversion, control theory, and motor drive systems
• PCB design using Altium Designer and circuit simulation (LTspice)
• EMI/EMC troubleshooting and resolution
• Thermal and reliability analysis (DFMEA, worst-case analysis)
• Mixed-signal electronics and embedded firmware familiarity
• High-voltage laboratory testing and hands-on troubleshooting
• Technical communication and design review presentation
