Mechanical Engineer

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

• Extreme ownership. Full autonomy. Own things end to end often taking on scope outside your core role without being asked to get things done.

• Velocity. We drive everything forward as fast as possible.

• 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.

The Capacity Delivery Team

Examples of key problems the team is working on

• Engineer gigawatts from drawing to energized, in months not years. Capacity Delivery owns technical execution across every build: the drawings, the field questions, and the engineering calls that keep multiple concurrent gigawatt sites moving.

• Engineer data centers that go up in months, not years. At that pace rework is not an option: problems get caught on paper or they cost a data hall.

• Design it once, build it a hundred times. Every site's lessons roll into the reference design on the way to 10s to 100s of GWs, so each build starts ahead of the last.

Role Scope

• Own mechanical engineering for assigned sites: review, field support, and closeout of cooling and piping scope.

• Review mechanical packages against the reference design and flag deviations with impact stated, not just difference.

• Answer field mechanical RFIs in hours and turn recurring ones into design fixes.

• Support startup and commissioning with engineering: flushing, filling, and balancing questions answered fast.

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 done mechanical engineering for data center or industrial plants.

• You read P&IDs, hydraulic calculations, and equipment schedules fluently.

• You've supported construction and commissioning in the field.

• Your RFI answers are fast and right, in that order and both.

• Bonus: Liquid cooling systems. PE track. Pipe stress analysis. Modular skid design.

We are committed to pay equity and transparency.
