About the Role

This position is within the core Engineering R&D group focused on our Solid-State Transformer (SST) platform. The team defines and delivers the next-generation power module, aiming for higher power density to reduce footprint and thermal load. We seek a technically deep power electronics engineer focused on increasing efficiency while reducing cost per watt.

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.
  • 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

  • 1+ years of nonacademic experience for Ph.D. candidates (3+ years for M.S. candidates), with greater experience expected for Staff-level candidates.
  • Hands-on experience in designing power electronics, particularly if focused on power density.
  • Ability to translate modeling and simulation to benchtop performance and reconcile differences between theory and practice.
  • Experience co-designing power electronics with mechanical and thermal engineering teams, balancing electrical performance against packaging and cooling constraints.
