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.\n\nWe'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.\n\nWe hire people who care deeply about this problem space. If that is you, please apply!\n\nHow We Operate\n\nBe a barrel. Full autonomy. Own things end to end, take on scope without being asked, no permission required to operate outside your core role.\n\nInsane urgency. We drive everything forward as fast as possible.\n\nReason from first principles. Challenge every assumption. Zero analogy thinking, no egos, the best idea wins.\n\nLove 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.\n\nBuild something that actually matters. If you're going to spend your time, spend it on something that matters to the world.\n\nThe Data Center Operations Team\n\nExamples of key problems the team is working on\n\nOperate at the scale of a nation, not a building. Accelerating toward 10s to 100s of GWs by the end of the decade, more than the entire electricity consumption of many countries. You won't just run a data center; you'll run infrastructure the size of a G7.\n\nFly the plane while it's being built. Running flawless operations inside a live construction zone, adapting in real time and turning the pace of build-out into our advantage. You will redefine operational excellence.\n\nWrite the playbook, don't inherit it. Most operators step into someone else's system. Here you build one, leaving your fingerprints on how the whole company runs. As we scale 100x, you'll set the standards, shape the operating model, and grow the team by the thousands.\n\nRole Scope\n\nServe as the most senior technical authority for operational mechanical and cooling infrastructure across the hyperscale AI data center fleet.\n\nLead site assessments and operational audits, and drive team technical readiness ahead of site activation.\n\nReview designs and specifications from an operational lens, and feed operational learnings back into design and manufacturing as the build model becomes productized.\n\nBe the senior voice on chillers, cooling towers, CDUs, and the liquid-cooling architectures AI infrastructure depends on.\n\nOwn mechanical operational readiness and the commissioning-to-operations handover for new sites.\n\nAuthor and approve high-risk mechanical MOPs, EOPs, and AOPs, and lead root cause analysis on significant cooling events.\n\nWhat We're Looking For\n\nThe 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.\n\nYou've spent a career on critical mechanical systems and you treat thermal precision as non-negotiable for AI workloads.\n\nYou command chilled water, chillers, cooling towers, CRAH/CRAC, pumps, CDUs, and direct liquid cooling in live environments.\n\nYou've authored and executed high-risk mechanical MOPs and led root cause analysis on significant cooling events.\n\nYou assess operational readiness at any site, audit the posture, and raise the standard.\n\nYou teach and build the mechanical readiness of teams ahead of activation.\n\nBonus: Hyperscale or large colocation at hundreds of MW. Direct liquid cooling and CDU operations. ASHRAE TC 9.9. Chilled water plant optimization. Uptime Institute.\n\nSalary & Benefits\n\nCompetitive total compensation package (salary + equity).\n\nRetirement or pension plan, in line with local norms.\n\nHealth, dental, and vision insurance.\n\nGenerous PTO policy, in line with local norms.\n\nTotal compensation may also include equity in the form of restricted stock units.\n\nWe are committed to pay equity and transparency.\n\nFluidstack is an Equal Employment Opportunity Employer.
