Job summary

Methode Electronics in the United States is seeking a Senior High Voltage Systems Engineer to lead design, development, and testing of high‑voltage architectures for next‑gen EV powertrains. You will architect 800V DC‑DC converters, planars, and power boards, collaborating across software, mechanical, and layout teams to deliver safe, reliable systems.

The role requires 5+ years in HV systems, deep knowledge of planar magnetics, thermal management, and automotive safety standards (ISO 26262).

Qualifications

• 5+ years hands-on experience developing high‑voltage systems exceeding 60V (ideally 400V–800V+)
• Experience with switching topologies, gate driver optimization, and magnetic component design
• Thermal management experience with liquid cooling or phase‑change cooling for high‑power electronics
• Familiarity with IPC-2221, IPC-9592 and automotive safety frameworks (ISO 26262/ASIL)
• Proficiency in MATLAB/Simulink, PLECS, PSpice or magnetic simulation tools and lab instruments
• Strong leadership and cross‑functional collaboration skills

Responsibilities

• Architect, design, and optimize 800V DC‑DC converters, onboard chargers, and traction inverters using wide‑bandgap semiconductors
• Design planar transformers and inductors to maximize power density and minimize parasitics
• Integrate power boards and multi‑layer PCBs within vehicle powertrain or grid system
• Perform thermal analysis and design active cooling solutions for high‑power modules
• Conduct system simulations, stress modeling, and FEA for magnetic flux optimization
• Lead hardware validation of HV batteries, inverters, and cabling harnesses in lab settings
• Guide cross‑functional teams to execute projects from concept to production
• Ensure safety with isolation monitoring, interlocks, and creepage/clearance requirements
• Troubleshoot hardware issues related to power flow, EMI/EMC, and component reliability
