Senior Power Electronics Design Engineer

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
