Job Description

The Role

General Motors is seeking a Power Electronics EMC Technical Specialist to lead electromagnetic compatibility engineering for Power Electronics & Traction Inverter hardware. The successful candidate will apply advanced knowledge of electromagnetic interference, electromagnetic susceptibility, signal and power integrity, high-voltage power electronics, and vehicle-level electrical integration to guide robust designs from concept through production.

This is a hands-on technical leadership role. The specialist will influence architecture and design decisions, develop practical mitigation strategies, lead root-cause investigations, and partner with internal engineering teams, suppliers, test organizations, and program leadership. The role is hybrid and based at the GM Global Technical Center - Estes Engineering Center.

What You'll Do
  • Define and lead EMC design strategies for Power Electronics & Traction Inverters, including requirements decomposition, risk assessment, design development, peer reviews, and validation planning.
  • Define design best practices to mitigate system level interactions between component EMC performance and vehicle level EMC requirements.
  • Develop and apply electromagnetic models and analysis methods to predict coupling paths, resonances, common-mode and differential-mode behavior, shielding effectiveness, grounding performance, and conducted and radiated emissions, both at the component level & at the vehicle level
  • Guide Power Electronics & Traction Inverter hardware design decisions involving power modules, busbars, laminated interconnects, gate-drive circuits, printed circuit boards, enclosures, filters, shielding, grounding, cables, and connectors.
  • Lead EMC mitigation activities across the design lifecycle, balancing electrical performance, thermal performance, packaging, manufacturability, reliability, cost, and timing.
  • Responsible for development of EMC load box and EMC test plan per GMW3097.
  • Schedule, execute, and document traction inverter EMC testing. Lead PRTS closure through structured root-cause investigations for electromagnetic interference and susceptibility issues, using measurement data, simulation, design-of-experiments, and engineering judgment.
  • Establish technical countermeasures and confirm effectiveness through focused testing and correlation between models, bench results, dynamometer testing, and vehicle testing.
  • Develop and maintain EMC operating-mode tracker covering charging, driving, V2L/V2G, AC/DC charging, inverter operation, and simultaneous APM/OBCM operation. Support EMC debugging for combined operation
  • Partner with Power Electronics & Traction Inverter design release engineering, controls and software, electrical architecture, vehicle integration, validation, reliability, manufacturing, purchasing, and supplier engineering teams.
  • Analyze grounding, shielding, cable routing and connector locations. Resolve vehicle-to-vehicle EMC variation.
  • Provide technical direction to suppliers and evaluate supplier EMC capability, analysis methods, test plans, design evidence, and corrective actions.
  • Review and approve EMC-related requirements, specifications, EMC test plan, EMC load box, drawings, analysis reports, test procedures, test reports, and design changes.
  • Create reusable EMC guidelines, checklists, modeling practices, and lessons learned for future Power Electronics & Traction Inverter programs.
  • PRTS ownership of EMC non-compliance related to OBCM component and AC charging system. Lead OBCM troubleshooting/scheduling plan with vehicle EMC team. Communicate technical risks, decisions, trade-offs, and recommendations to engineering and program leadership.
  • Mentor engineers and raise the organization's capability in power-electronics EMC design and troubleshooting.


Required Qualifications
  • Bachelor's degree in electrical engineering, electronics engineering, or a related discipline.
  • 8+ years of relevant hands-on hardware experience with high-voltage power electronics, AC/DC and DC/DC converters, inverters, or electric-drive systems
  • Strong Expertise in electromagnetic compatibility (EMC), including, high-voltage AC conducted emissions and Radiated Emission compliance, Electromagnetic immunity/susceptibility, common-mode and differential-mode noise suppression, grounding, shielding, filtering, impedance, and signal/power integrity analysis.
  • Significant experience designing, analyzing, or validating EMC performance for power electronics, electric drives, Power Electronics & Traction Inverters, converters, or similar high-power systems.
  • Demonstrated expertise in electromagnetic interference and susceptibility mechanisms, including conducted and radiated coupling, common-mode and differential-mode currents, grounding, shielding, filtering, and cable effects.
  • Experience with EMC modeling, simulation, or analytical methods and the ability to correlate predictions with laboratory and vehicle-level measurements.
  • Strong understanding of high-voltage power-electronics hardware, including switching devices, power modules, gate drives, bus structures, printed circuit boards, and Power Electronics & Traction Inverter packaging.
  • Experience planning, executing, or interpreting EMC testing and resolving failures through data-driven root-cause analysis.
  • Ability to lead cross-functional technical decisions and influence internal teams and suppliers without direct authority.
  • Strong written, verbal, and presentation skills, including the ability to communicate complex technical issues to leadership.
  • Willingness to travel periodically to supplier, test, and vehicle-development locations as needed.


Preferred Qualifications
  • Master's degree or advanced technical training in electrical engineering, electromagnetics, power electronics, or a related field.
  • 10+ years of relevant hands-on hardware experience with high-voltage power electronics, AC/DC and DC/DC converters, inverters, or electric-drive systems
