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 TeamExamples of key problems the team is working on- Design the module that makes 6-month data centers possible. Fluidstack builds data centers in months, not years, and that speed lives in the modular product: a data center engineered as a manufactured unit, not a construction project.
- Take designs from concept to the manufacturing line in weeks. Concept, released drawings, first article, and rate production on a compressed schedule, with the factory building from your work the same month you release it.
- Engineer for the thousandth unit, not the first. On the way to 10 GW, every drawing, tolerance, and BOM decision has to survive rate manufacturing, so repeatability is designed in from the start.
Role Scope- Engineer the mechanical systems of the modular product: cooling, piping, and airflow from concept to released drawings.
- Own the liquid cooling loops, pumps, and heat rejection design the modular product's density depends on.
- Solve the integration problems where mechanical meets structure and electrical: routing, interfaces, and tolerances where the disciplines collide.
- Support the factory and field: mechanical RFIs answered same-day, fixes engineered into the next revision.
- Prototype and validate: mockups, fit checks, and first-article reviews you attend in person.
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.
- Your drawings build clean: fabricators rarely call, and when they do you fix the drawing.
- You work across disciplines instead of throwing problems over walls.
- You've supported production launches of your own designs.
- You iterate fast without losing configuration control.
- Bonus: Liquid cooling depth. Sheet metal and piping design. 3D CAD mastery (SolidWorks, Inventor, Revit). DFM instincts.
We are committed to pay equity and transparency.
