Fluidstack DC Power Systems and Protection Engineer responsible for protection and grounding of medium-voltage and low-voltage DC power buses. Specifies and co-develops DC breakers, fuses, and disconnects for high-current applications.
Responsibilities
Own protection and grounding for every zone from bipolar medium-voltage DC bus to 1,500 V solar and battery bus and 800 V racks
Specify and co-develop with vendors DC breakers, fuses, and disconnects for buses from medium-voltage feeders to hall buses
Design fault clearing without conventional breakers where possible using SSTs

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 protection for a medium- or high-voltage DC system (MVDC, HVDC, shipboard, rail, or DC microgrid) and seen it through commissioning.
You've built and run electromagnetic transient models of converter-dominated systems, and used them to set breaker, fuse, or relay requirements.
You've made a grounding call (solid, resistance, or floating) and defended its trade-off between fault current and insulation stress.
You've specified, designed, or qualified DC breakers, fuses, or switchgear for medium-voltage or high-current DC, and tested them through interruption.
You've written protection requirements a converter or breaker vendor had to redesign to meet.
You find the failure case others missed and can show it in a single simulation plot.
Bonus: DC interruption technology (solid-state and hybrid breakers, high-speed DC fuses). EMT simulation (PSCAD/EMTDC, EMTP, PLECS, MATLAB/Simulink). Protection coordination and relay settings (ANSI device functions, IEC 61850). MVDC standards (IEEE 1709). Professional Engineer license (PE).
We are committed to pay equity and transparency.
