• 5 or more years of relevant experience
• Demonstrated experience designing and developing DC/DC converters or AC/DC converters
• Strong understanding of power-electronics theory, converter topologies, switching devices, magnetics, gate drives, control methods, protection circuits, and power losses.
• Experience with electrical design analysis, including derating, worst-case analysis, loss calculations, thermal analysis, and design-for-reliability methods.
• Experience with EMC/EMI design and troubleshooting in power-electronics modules.
• Understanding of high-voltage automotive systems, isolation, grounding, pre-charge, contactors, fault handling, and laboratory safety.
• Hands-on experience with high-voltage laboratory equipment, oscilloscopes, power analyzers, and electronic loads.
• Experience with modeling and simulation tools such as MATLAB/Simulink, PLECS, PSIM, LTspice, or equivalent.
• Ability to diagnose complex technical issues, make data-based recommendations, and work effectively under demanding schedules.
• Strong written, verbal, presentation, collaboration, and technical leadership skills.
• Ability to work independently and effectively with domestic and international teams, suppliers, and cross-functional partners.
• Experience with DFSS, Design for Manufacturing, and Design for Assembly

Nice To Haves

• Master’s or Ph.D. degree in Electrical Engineering, Power Electronics, or a related discipline.
• Experience with SiC, GaN, IGBT, advanced switching, high-frequency operation, soft switching, or multilevel converters.
• Experience with power-density optimization, planar or integrated magnetics, common cooling structures, or embedded power modules.
• Experience with vehicle-level charging and accessory-power.
• DFSS BB Certification
• Experience with PCB design, electrical CAD/CAE, thermal simulation, computational tools, or automated test/data-analysis methods.
• Familiarity with ISO 26262, ASPICE, GMW requirements, applicable charging standards, and automotive high-voltage safety practices.
• Experience leading advanced-technology work, supplier development, technical workgroups, or cross-functional engineering teams.
• Experience preparing technical publications, invention disclosures, patents, or internal engineering standards.

Responsibilities

• Develop converter architectures and power-stage concepts, including topology selection, semiconductor selection, magnetics, capacitors, sensing, gate drive, protection, isolation, pre-charge, and filtering
• Create and review schematics, power-stage designs, control-board interfaces, electrical interfaces, and design documentation for advanced power-converter prototypes and production-intent concepts.
• Perform design trade studies using simulation, competitive benchmarking, component teardowns, cost analysis, efficiency analysis, power-density analysis, and reliability considerations.
• Develop and analyze models for converter steady-state, transient, switching, control-loop, thermal, loss, fault, current-sharing, and system-interaction behavior.
• Design for EMC/EMI performance, electrical isolation, high-voltage safety, functional safety, serviceability, manufacturability, and environmental robustness.
• Lead or support worst-case circuit analysis, derating analysis, DFMEA, fault-tree analysis, design reviews, and design-verification planning.
• Plan and execute prototype builds, bring-up, bench testing, hardware debugging, characterization, and design iteration in high-voltage laboratory environments.
• Collaborate with controls and embedded-software engineers on modulation, startup/shutdown, protection, diagnostics, communication, current sharing, and system-level control strategies.
• Provide technical direction to suppliers and participate in supplier technical reviews, design reviews, DFMEA reviews, prototype builds, test reviews, and issue-resolution activities.
• Work with Product Engineering, Systems Engineering, Modeling and Analysis, Cost Engineering, Planning, Program, Manufacturing, and Vehicle Integration teams through ATW, BA, and early GPDP activities.
• Drive opportunities for cost reduction, efficiency improvement, power-density improvement, commonization, packaging reduction, and technology reuse across vehicle programs.
• Prepare clear technical reports, recommendations, presentations, and gate deliverables for engineering leadership, peers, suppliers, and cross-functional stakeholders.
• Document lessons learned, design methods, intellectual property, and process improvements.
