Job summary

General Motors Company is seeking a Senior Electrical Power Design Engineer to lead the design, validation, and integration of power delivery systems for automotive ECUs across 12V-48V and 400V-800V domains.

You will drive simulations, PI/EMI/EMC optimization, component qualification, and lab validation while mentoring engineers and shaping design standards for electrification and SDV strategies.

Qualifications

• Bachelor's degree in Electrical Engineering, Power Electronics, or related field required.
• 5+ years of experience designing power electronics for automotive or high-performance embedded hardware systems.
• Experience developing high-voltage automotive circuitry (400V-800V), including propulsion, charging, battery management, or DC-DC power applications.
• Expertise with IGBT, SiC, and GaN switching technologies and their design considerations.
• Strong knowledge of power conversion topologies, power supplies, voltage regulation, and high-current power distribution.
• Experience with PCB design, layout optimization, thermal management, and power-aware board architectures.
• Proficiency with SPICE, LTspice, PLECS, MATLAB, or similar power simulation tools.
• Hands-on experience validating power electronics using oscilloscopes, power analyzers, and thermal test equipment.
• Deep understanding of power integrity, EMI/EMC, thermal design, and high-voltage safety.
• Proven ability to solve complex technical challenges and influence engineering decisions across teams.

Responsibilities

• Design and develop power delivery architectures across low-voltage (12V-48V) and high-voltage (400V-800V) domains.
• Perform power simulations and analysis for efficiency, load regulation, transient response, thermal performance, and system stability using SPICE, PLECS, MATLAB, HyperLynx, or Ansys.
• Drive power integrity, EMI/EMC, thermal, and reliability optimization throughout the product lifecycle.
• Select and qualify power components including MOSFETs, controllers, inductors, capacitors, and emerging power technologies.
• Build, test, and validate power systems using lab equipment such as oscilloscopes, power analyzers, and thermal imaging tools.
• Troubleshoot and resolve complex power-related issues during development, validation, and production.
• Develop power design standards, specifications, best practices, and verification methodologies.
• Provide technical leadership, mentor engineers, and influence cross-functional hardware architecture decisions.
