Senior Power Electronics Design Engineer, Magnetics
Amperesand
San Francisco, US
On-site
Job Description
Responsibilities
Design isolated and non-isolated converter stages using 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
Design magnetics to meet applicable safety, isolation, and thermal standards
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 and guide high-power high-frequency PCBA designs
Work in close coordination with mechanical designers, manufacturing and test engineers to own the complete development cycle
Own the design validation of the magnetics components to validate performance targets, isolation requirements
Qualifications
M.S. or Ph.D. in Power Electronics, Electromagnetics or related field
4+ years' experience in magnetics design and in power conversion design
Strong fundamentals in electromagnetics and material properties
Experience working with SiC/GaN devices in high power density designs
Good understanding of loss mechanisms in semiconductor devices and high-frequency magnetics
Knowledge of Medium Voltage insulation coordination, hands-on experience with Hi-pot, Partial Discharge and Basic Impulse Test
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.
