ABOUT FLUIDSTACK

We exist to make humanity more free. For most of human history, you farmed or you starved. Technology gave people more time for the things they wanted to do, instead of things they had to do. Powerful AI will be the biggest lever for human choice we've ever built - but only if models are aligned with what humanity actually wants. There are groups building AI who don't share these goals. Whoever deploys frontier compute infrastructure fastest will decide whether AI expands human freedom or shrinks it.

We're singularly focused on delivering 10 to 100s of GWs of compute faster than anyone else, rethinking every layer of the stack. We acquire power, design and build data centers, and operate them - with teams spanning hardware and software. Speed and scale are our key differentiators. Come be a part of building civilization-scale infrastructure for AI.

We hire people who care deeply about this problem space. If that is you, please apply!

HOW WE OPERATE

Be a barrel. Full autonomy. Own things end to end, take on scope without being asked, no permission required to operate outside your core role.
Insane urgency. We drive everything forward as fast as possible.
Reason from first principles. Challenge every assumption. Zero analogy thinking, no egos, the best idea wins.
Love of the game. The frontier of AI is the most interesting problem of our time. We put in long hours at high intensity to push the frontier forward.
Build something that actually matters. If you're going to spend your time, spend it on something that matters to the world.

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. https://jobs.ashbyhq.com/fluidstack/05c2e69c-42f9-4fcb-9cf0-a467aaf98f1c

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.
