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 Modular Team

The Modular team is turning the data center into a manufactured product: structural modules engineered, built, and shipped from a production line instead of stick-built in the field.

Examples of key problems the team is working on:

• Take a first-of-a-kind modular data center product from released drawings to rate production on a live manufacturing line.

• Engineer frames, enclosures, and lifting and transport structures that survive fabrication, craning, road transport, and decades of service.

• Close the loop between the factory floor and the design office fast enough that every unit builds cleaner than the last.

• Hold configuration control while the product iterates at manufacturing speed, not construction speed.

Role Scope

• Own the structural systems of the modular product on the line, frames, enclosures, and lifting and transport structures, from released drawings through rate production.

• Live on the Phoenix manufacturing line: walk the floor daily, catch fit-up and weld issues at the station where they happen, and disposition them on the spot.

• Run structural support for the factory in real time, answering RFIs same-day from the floor and engineering fixes into the next revision, not a someday backlog.

• Run first-article reviews and fit checks in person as units come down the line, with findings documented tightly enough to drive drawing changes.

• Close the loop to design: feed what the line learns back into drawings, tolerances, and the BOM so the same issue never surfaces 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 structures for complex physical products, modular construction, or heavy fabrication, hands-on, not from a review desk.

• You've worked on a shop floor or fabrication line, and dispositioning a nonconformance with the line waiting is familiar work: use-as-is, rework, or stop, decided in the moment and defensible afterward.

• Your drawings build clean. Fabricators rarely call, and when they do, you fix the drawing rather than explain it away.

• You've supported production launches of your own designs and stayed with them through the ugly early units.

• You iterate fast without losing configuration control: every floor fix lands back in the drawing, the tolerance stack, or the BOM.

• Bonus: PE license, steel and sheet metal design, structural detailing standards (AISC, AWS), weld inspection or NDE familiarity, and DFM instincts.

We are committed to pay equity and transparency.
