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 the enclosure and cooling for high-power converters (MV drives, inverters, SSTs, traction, or EV fast chargers) and shipped them.
You've laid out high-voltage busbars and conductors to meet creepage and clearance rules in a tight volume.
You've built liquid cooling for power electronics, from cold plates to heat exchangers, and matched your thermal models to test data.
You've designed parts for volume manufacture with a contract manufacturer and fixed what broke on the line.
You've designed hardware for outdoor or industrial sites: dust, humidity, vibration, and shipping loads.
Bonus: Thermal and flow simulation (CFD, Ansys Icepak, COMSOL). Mechanical CAD (SolidWorks, Creo, NX). Insulation coordination standards (IEC 60664, UL 840). Enclosure ratings (NEMA, IP). Design for manufacture and assembly (DFM, DFA).
We are committed to pay equity and transparency.
