Commitment to pay equity and transparency.
Opportunity to work on cutting-edge technology in AI data centers.
Collaborative environment with a focus on innovation and problem-solving.
Full Job Description
The Product Engineering Team
Product Engineering builds the power and cooling systems that let Fluidstack deliver gigawatt-scale AI data centers faster and denser than the grid-standard supply chain allows. The SST group is designing solid-state transformers as a core building block of that power architecture.
Examples of key problems the team is working on
Architect a medium-voltage solid-state transformer that can be manufactured, serviced, and scaled across gigawatt-scale campuses, not just demonstrated in a lab.
Define the interface between the SST and the MVDC distribution system, including protection, control boundaries, and fault behavior.
Build a semiconductor and magnetics supply strategy that survives a thin 10kV SiC market over a multi-year horizon.
Take converter hardware from topology selection through working prototypes on a schedule that data center construction actually depends on.
Role Scope
Design the power stage and gate-driver boards for every SST cell: SiC half-bridge modules, isolated gate drivers, auxiliary power, and current and voltage sensing.
Lay out boards for fast-switching SiC with low-inductance commutation loops and creepage and clearance that hold at tens of kilovolts to ground.
Design isolated auxiliary power and signal links for boards that float at high voltage inside a series stack of cells.
Bring up boards on the bench with the technicians and test engineer, and close design spins from prototype cells to pilot units.
Hand off manufacturing-ready packages (fabrication and assembly data, test points, fixtures) to contract manufacturers.
What We're Looking For
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 brought up gate-driver and power-stage boards for SiC or GaN converters at hundreds of volts and above.
You've laid out boards that switch at high dv/dt without false triggering, and can show the loop inductance you designed for.
You've designed isolated power supplies or signal isolation for circuits floating at high voltage.
You've met creepage and clearance requirements on a high-voltage board and passed a hipot test with it.
You've taken a board from schematic to a contract manufacturer and fixed what failed at first article.
Bonus: PCB design tools (Altium, Cadence). Interconnect design certification (IPC CID, CID+). Power conversion board standards (IPC-2221, IPC-2152, IPC-9592). Sensing for power electronics (Rogowski coils, isolated amplifiers). Laminated busbar design.
We are committed to pay equity and transparency.
