Fluidstack Magnetics Engineer at Fluidstack designing medium-frequency transformers for solid-state transformer cells. Responsible for core material selection, winding structures, insulation, and cooling design.
Responsibilities
Design the medium-frequency transformer at the heart of every SST cell: hundreds of kilowatts at tens of kilohertz, insulated for tens of kilovolts DC to ground
Choose core materials, winding structures, insulation, and liquid cooling that balance loss, size, and cost across thousands of units
Prove each design on the bench with hi-pot, partial-discharge, impulse, and thermal-cycling tests
Set the acceptance tests every production unit must pass

Required
The below is a starting point. We always make space for exceptional people, so if you don't fit this role exactly, tell us where you would.
You've designed and built high-frequency transformers or inductors for power converters at tens to hundreds of kilowatts.
You've designed insulation for medium-voltage magnetics and run hi-pot, partial-discharge, and basic impulse tests yourself.
You've used FEA to predict losses, leakage inductance, and hot spots, then matched those predictions to measured data.
You've pulled heat out of a winding through its insulation system, by cold plate or liquid, without creating partial discharge.
You've taken a magnetic component from prototype to volume production with an outside supplier.
You've traced a test or field failure to its root cause in the insulation, core, or winding.
Bonus: Core materials (nanocrystalline, ferrite). Solid and cast insulation (epoxy, silicone potting). Magnetics FEA (ANSYS Maxwell, COMSOL). Integrated leakage design for resonant converters (LLC, DAB). Transformer and insulation standards (IEC 61558, UL 1446).
We are committed to pay equity and transparency.
