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

• High 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 Commissioning Team

Examples of key problems the team is working on

• Help stand up a Cx program for 50GW+ of DCs this decade.

• Develop plans for Cx and QA/QC for first-of-a-kind modular data center designs.

• Drive development and implementation of automated L4/L5 commissioning.

Role Scope

• Own the field commissioning program across all MEP systems on hyperscale data center projects at 100MW+, serving as the primary on-site authority for mechanical, electrical, and controls integration.

• Lead every commissioning phase from pre-functional testing through functional performance testing and Integrated Systems Testing to owner acceptance.

• Own startup and energization sequencing for chillers, dry coolers, FCUs, pumps, HVAC, switchgear, UPS, generators, and BMS/EPMS.

• Own the six-week look-ahead and constraint log, surfacing and resolving upstream constraints before they hit the schedule.

• Run site meetings with clients, consultants, and trades, presenting commissioning status, risk, and recovery plans.

• Travel at least 50% to project sites.

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 owned large-scale commissioning programs from mobilization through owner acceptance as a superintendent on hyperscale data centers at 100MW+.

• You have deep mechanical commissioning expertise on chillers, dry coolers, FCUs, pumps, cooling towers, and HVAC in redundant live environments, plus enough electrical and controls command to lead integrated MEP commissioning.

• You've worked the owner's-rep or client side, so you anticipate owner expectations and interpret acceptance criteria before gaps become schedule impacts.

• You run high-stakes client meetings with confidence and drive accountability across every party on site.

• You command six-week look-ahead scheduling and visual planning tools (takt boards, zone maps, pull planning), and you know energized-work safety and OSHA in mission-critical environments.

• Bonus: Lean planning practices. Mission-critical data center delivery standards. Scheduling software fluency.

Benefits

• Competitive total compensation package (cash + equity).

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

• Health, dental, and vision insurance.

• Generous PTO policy, in line with local norms.

The base salary range for this position is $150,000 - $250,000 per year, depending on experience, skills, qualifications, and location.
