Original job description

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

Build Fluidstack's SST test capability, from a back-to-back full-power rig to high-voltage insulation testing, in-house or with a partner lab.
Verify vendor and in-house SST hardware independently: efficiency curves, temperature rise, partial discharge, and fault response at rated voltage and power.
Run qualification and reliability campaigns (thermal cycling, power cycling, humidity, accelerated life) that catch insulation and solder failures before the field does.
Write the acceptance tests every production unit must pass, and the end-of-line test each unit runs before it ships.
Turn test results into pass, fail, or redesign decisions written so the architect, the vendor, and leadership can act on them.

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 built and run high-power test setups for power converters, including back-to-back or regenerative rigs at hundreds of kilowatts or more.
You've run partial-discharge, hipot, and impulse tests at medium voltage and interpreted the results yourself.
You've designed reliability test plans (HALT, thermal and power cycling) and traced failures to root cause.
You've written test procedures a technician or contract manufacturer can follow without you in the room.
You've worked around energized medium-voltage equipment, set the lab safety rules others followed, and hold current NFPA 70E qualified-person training.
Bonus: Certification testing (UL, IEC, witness testing with a test lab). Data acquisition and automation (Python, LabVIEW, NI hardware). Power analysis and fast current sensing (power analyzers, Rogowski coils). Electrical safety practice (NFPA 70E, arc flash). Manufacturing end-of-line test.

We are committed to pay equity and transparency.
