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 Supply Chain Team

Examples of key problems the team is working on

• Stand up the commissioning program for 10s to 100s of GWs of capacity this decade.

• Run commissioning and QA-QC for first-of-a-kind modular data centers.

• Automate Level 4 and Level 5 commissioning.

Role Scope

• Lead mechanical commissioning across flushing, cooling, heat rejection, and liquid cooling systems for high performance data centers, spanning Level 1 through Level 5 commissioning phases.

• Drive the Testing & Verification program for mechanical cooling, heat rejection, and data hall thermal systems, working with commissioning agents and engineers from pre-site testing through on-site functional testing.

• Own commissioning documentation across multiple projects and sites, tracking issues, test results, and reports with enough rigor to hold up under an owner audit.

• Run on-site commissioning operations across general contractors, designers, and vendors: inspections, safety enforcement, progress tracking, and issue resolution.

• Close out final operational handover for mechanical systems, confirming every system is ready for service before occupancy.

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 have a minimum of 10 or more years of hands-on commissioning experience

• You've commissioned data center mechanical equipment firsthand: chillers, cooling towers, CRAH/CRAC units, AHUs, CDUs, direct-to-chip liquid cooling, pumps, hydronic piping, and BMS/BAS integration.

• You've run hydronic flushing, cleaning, and pressure and hydrostatic testing on process piping, and you know AABC/NEBB TAB standards well enough to catch a bad test result before it gets signed off.

• You've built and executed Testing & Verification programs end to end, from pre-site functional testing through on-site startup, troubleshooting, and support.

• You show up in design and constructability reviews with commissioning and operations in mind, catching issues before they're built into concrete and steel.

• You keep commissioning records, issue logs, and test reports rigorous enough that any of them could stand up to an owner or insurer audit.

• You hold a degree in Mechanical Engineering.

• Bonus: ASHRAE or BCxA commissioning guideline experience. Controls or electrical systems knowledge. Hyperscale or mission-critical data center project experience. Managing multiple concurrent project sites.
  

Benefits

• Competitive total compensation package (salary + equity).

• Retirement or pension plan, in line with local norms.

• Health, dental, and vision insurance.

• Generous PTO policy, in line with local norms.

We are committed to pay equity and transparency.
