Senior Power Electronics Engineer

About the role

This position sits within the core Engineering R&D group focused on our Solid-State Transformer (SST) platform. Our team is responsible for defining and delivering the next-generation power module, with higher power density to reduce footprint and thermal load.

Responsibilities

• Design and develop power conversion circuits and magnetics for the SST platform, optimizing for power density, efficiency, and thermal performance
• Evaluate and integrate advanced power semiconductor devices (particularly, GaN) and planar magnetics to increase power throughput while shrinking module footprint
• Translate modeling and simulation results into benchtop prototypes, and reconcile differences between predicted and measured performance
• Drive design trade-offs across power density, efficiency, thermal management, and cost per watt to meet next-generation product targets
• Co-design with mechanical and thermal engineering to jointly optimize packaging, cooling, and power density, and collaborate with controls engineering to integrate power modules into the SST platform
• Lead root-cause analysis and design iteration based on test data to continuously improve power density and reliability

Requirements

• M.S. or Ph.D. in Electrical Engineering
• 4+ years of nonacademic experience for Ph.D. candidates (6+ years for M.S. candidates), with greater experience expected for Senior Staff-level candidates
• Hands-on experience in designing power electronics, particularly if focused on power density
• Familiarity with advanced power semiconductor devices and magnetics (particularly planar transformers)
• Experience co-designing power electronics with mechanical and thermal engineering teams, balancing electrical performance against packaging and cooling constraints
• Ability to lead technical execution of significant power electronics designs with a high degree of autonomy, escalating major trade-offs as needed
• Experience mentoring less experienced engineers and contributing to technical design reviews within the team

Qualifications

• Technical depth in power electronics
• Strong problem-solving and analytical skills
• Excellent communication and collaboration abilities

Skills

• Advanced power semiconductor devices (particularly GaN)
• Planar magnetics
• Power electronics design
• Thermal management
• Cost optimization
