Mechanical Commissioning Lead

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.

Role Scope

• Commission the mechanical systems of first units: cooling plants, distribution, and heat rejection verified to design.

• Execute and improve the scripts: functional tests run, gaps found, and the reference package fixed.

• Analyze the data: trends and test results reconciled against the thermal model.

• Support the factory: mechanical FAT processes for modules before they ship.

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 commissioned mechanical or HVAC systems on data centers or industrial plants.

• You execute functional tests rigorously and document what actually happened.

• You read trend data and find the story in it.

• You've caught design errors during commissioning and made sure they got fixed upstream.

• You work clean in live environments.

• Bonus: Liquid cooling commissioning. Test and balance interface. FAT development. Commissioning software platforms.

We are committed to pay equity and transparency.
