Job Description

Responsibilities:

  • You will be responsible for designing isolated and non-isolated converter stages, implementing advanced topologies such as multi-level converters, cascaded H-bridges, Dual Active Bridge (DAB) and ensuring robust protection and safety compliance for MV/LV systems.
  • Perform trade-off analysis and optimization of power conversion hardware to balance between loss, cost and size across Semiconductors, Magnetics and Cooling components
  • Develop modulation techniques and control algorithms to handle corner-case operation of modular power stages.
  • Develop Static and Dynamic equivalent models for power stage hardware to support closed-loop control implementations.
  • Design and verify high-voltage isolation strategies using magnetically and optically isolated signal and power paths across LV-MV domains.
  • Use FEA simulations to design magnetics; guide high-power high-frequency PCBA designs.
  • Work in close coordination with mechanical designers, manufacturing and test engineers to own the complete development cycle.

Qualifications:

  • M.S. or Ph.D. in Power Electronics, Electromagnetics or related field.
  • 2+ years' experience in power conversion design.
  • Strong fundamentals in power converter topologies, modulation techniques, and design trade-off analysis.
  • Experience working with SiC/GaN devices in high-density designs.
  • Good understanding of loss mechanisms in Semiconductor devices, Passive EE components and high-frequency magnetics
  • Demonstrated expertise in simulation-driven design and figure-of-merit evaluation across topology, controls, devices, and magnetics.
  • Knowledge of EMI/EMC test Standards and Electrical Safety (IEC, UL) Standards.
  • Strong analytical skills for interpreting simulation and test data to guide design revisions.
  • Excellent written and verbal communications in English
  • Willingness and ability to travel up to 10% including internationally

Please note: This role requires working on-site 5 days a week. We do not offer hybrid or remote options.
