About the role

Company Overview Amperesand is reinventing how the world powers its most critical systems.
Electricity demand is skyrocketing, driven by AI factories, electric vehicles, and modern industrial growth.
Energy supply is shifting to incorporate a more diverse mix of resources - including solar, gas, and batteries - at a massive scale.

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.
Use FEA simulations to design magnetics; guide high-power high-frequency PCBA designs.
Amperesand is building hardware and software that rewrites this broken power infrastructure playbook to support a new era of energy abundance.

Knowledge of EMI/EMC test Standards and Electrical Safety (IEC, UL) Standards.
Willingness and ability to travel up to 10% including internationally
M.S. or Ph.D. in Power Electronics, Electromagnetics or related field.
2+ years' experience in power conversion design.
