About Fluidstack

Technology is the most important tool humans have found for improving the human condition, but it is not a default good. It is a lever for ideology.

Today the most powerful technology in history is being built: machines that solve problems better than humans can. The most important mission of our generation is to imbue AI with democratic values: error-correcting institutions, freedom of speech, individual liberties. AI trains and runs on massive compute clusters. Whichever ideology builds the infrastructure the fastest is the ideology that will endure. Democracy is delicate and won't survive this technology by default.

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 Modular Team

The Modular team builds first-of-a-kind modular data centers on a production line, turning what is normally a construction project into a manufactured product.

Examples of key problems the team is working on:

Engineer modular data center units that can be built, tested, and shipped from a factory line instead of assembled on site
Prove out controls, sensors, and I/O on every unit before it leaves the floor, so commissioning in the field starts from a known-good baseline
Close the loop between the manufacturing line and the design team, so wiring, logic, and BOM issues found at a station get engineered out of the next revision
Compress the time from first article to repeatable production without losing configuration control

Role Scope

Engineer and check out the controls of the modular product on the line, PLCs, BMS integration, sensors, and I/O, owning every point from panel to termination
Live on the Phoenix manufacturing line: walk the floor daily, catch wiring and I/O issues at the station where they happen, and disposition them on the spot
Run point-to-point checkout, loop checks, and first-article functional tests in person as units come down the line, with results documented well enough to stand behind at handoff
Own real-time controls support for the factory: answer controls RFIs same-day from the floor and engineer fixes into the next revision, not a punch list
Close the loop to design: feed what the line learns back into wiring diagrams, logic, and the BOM so the same defect never ships twice

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 engineered or commissioned controls systems hands-on: PLC, BMS, or industrial automation, from integrators, BMS contractors, or data center commissioning firms
You've done point-to-point checkout and loop checks on real panels at volume, not just reviewed them on paper
You've worked on a shop floor or production line, and dispositioning a nonconformance in the moment is familiar work, not an escalation
You've supported production launches or startups of systems you helped build, and stayed until they ran
You iterate fast without losing configuration control: when the drawing, the wiring, and the logic disagree, you can isolate which one is wrong and keep the line moving while it gets fixed
You write the logic, then stand at the cabinet proving every point
Bonus: PLC programming (Rockwell, Siemens), data center BMS platforms, panel and wiring diagram standards, or instrumentation depth

We are committed to pay equity and transparency.
