Job summary

General Motors’ Compute & Connectivity Hardware team seeks a Power Electronics Engineer to lead the design of robust power delivery for GM’s ECUs across 12V-48V and 400V-800V domains. You will drive simulations, validation, and cross-functional collaboration to ensure scalable, reliable high-voltage automotive power solutions.

The role emphasizes leading edge power topology choices, component qualification, and design for manufacturability, with hands-on lab testing and mentoring of engineers.

Qualifications

• 5+ years designing power electronics for automotive or high-performance embedded hardware.
• Experience with 400V-800V automotive circuitry (propulsion, charging, BMS, DC-DC).
• Expertise with IGBT, SiC, and GaN switching technologies.
• PCB design, layout optimization, thermal management, and power-aware board architectures.
• Proficient with SPICE, LTspice, PLECS, MATLAB.

Responsibilities

• Design and develop power delivery architectures for low- and high-voltage domains.
• Perform power simulations for efficiency, regulation, transient response, and thermal performance.
• Drive power integrity, EMI/EMC, thermal, and reliability optimization throughout the lifecycle.
• Select and qualify power components (IGBT, SiC, GaN, inductors, capacitors).
• Build, test, and validate power systems with lab equipment (oscilloscopes, power analyzers).
• Troubleshoot complex power-related issues during development and production.
• Develop power design standards, specs, and verification methodologies.
• Provide technical leadership and mentor engineers across hardware teams.
