Magnetics Engineer, Medium-Frequency Transformers
FluidStack — Austin, Texas, United States · In-Person · Senior
Role description
Role Overview
Design and build high-frequency transformers or inductors for power converters at tens to hundreds of kilowatts. Work on medium-voltage magnetics, insulation, and leakage inductance. Collaborate with the Product Engineering Team to deliver gigawatt-scale AI data centers faster and denser than the grid-standard supply chain allows.
What You Will Do
Design the medium-frequency transformer at the heart of every SST cell, choose core materials, winding structures, insulation, and liquid cooling, and prove each design on the bench with hi-pot, partial-discharge, impulse, and thermal-cycling tests.
Why It Might Be a Fit
We're looking for exceptional people who care deeply about building civilization-scale infrastructure for AI. If you have experience designing and building high-frequency transformers or inductors, and have a passion for working on complex problems, we want to hear from you.
Requirements
- Designed and built high-frequency transformers or inductors for power converters at tens to hundreds of kilowatts
- Designed insulation for medium-voltage magnetics and run hi-pot, partial-discharge, and basic impulse tests yourself
- Used FEA to predict losses, leakage inductance, and hot spots, then matched those predictions to measured data
- Pulled heat out of a winding through its insulation system, by cold plate or liquid, without creating partial discharge
- Taken a magnetic component from prototype to volume production with an outside supplier
- Traced a test or field failure to its root cause in the insulation, core, or winding
