About FluidstackWe 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 TeamThe Modular team turns data center capacity into a manufactured product: modules engineered, built, and tested on a production line, then shipped to site ready to energize.Examples of key problems the team is working on:
- Take modular data center designs from released drawings through first article to rate production on the Phoenix manufacturing line
- Engineer cooling, piping, and airflow systems that build clean at station, pass pressure test the first time, and hold up in the field
- Close the loop between the factory floor and design so every build issue gets killed in the drawing, not patched unit by unit
- Compress the cycle from design revision to line implementation without losing configuration control
Role Scope- Own the mechanical systems of the modular product on the line, cooling, piping, and airflow, from released drawings through rate production
- Live on the Phoenix manufacturing floor: walk the line daily, catch piping and assembly issues at the station where they happen, and disposition them on the spot
- Run first-article reviews, fit checks, and pressure tests in person as units come down the line
- Answer mechanical RFIs same-day from the floor, and engineer the fix into the next revision rather than leaving it as a one-off deviation
- Close the loop to design: feed what the line learns back into drawings, tolerances, and the BOM so the same issue never builds twice
What We're Looking ForThe 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 mechanical systems for complex physical products or modular construction hands-on, not from a desk
- 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 of your own designs and stayed with them through the problems that only show up at rate
- Your drawings build clean: fabricators rarely call, and when they do, you fix the drawing
- You've run first-article builds and pressure tests personally, and when something failed, you traced it to the drawing or the process rather than reworking units one at a time
- You iterate fast without losing configuration control: every fix lands in a controlled revision, and the line always knows which one it's building
- Bonus: liquid cooling depth, piping and pressure testing experience, sheet metal design, or strong DFM instincts
Physical Requirements- Work in non-climate-controlled environments, including active construction areas, data halls, electrical and mechanical rooms, and outdoor spaces. Temperatures can be high or low, and conditions can be humid, loud or dusty.
- Lift, carry, push and pull up to 40 pounds on your own.
- Sit, stand, walk, kneel, bend and crouch for long periods, including full shifts on your feet.
- Wear the required personal protective equipment (PPE), such as hard hats, safety glasses, steel-toed boots, gloves and hearing protection, and follow site safety rules.
- Climb stairs and ladders, and move around equipment, cable trays and uneven surfaces.
We are committed to pay equity and transparency.
