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 OperateExtreme 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 Data Center Design TeamExamples of key problems the team is working onLead the design, development, and execution of 10s to 100s of GWs of data centers this decade.Drive the next generation of liquid cooling and electrical distribution systems.Develop and scale first-of-a-kind modular data centers.Influence behind-the-meter designs and planning for multi-GW campuses.Role ScopeOwn mechanical systems end to end for AI-optimized, high-density data centers, from early concept and analytical modeling through final build and deployment.Lead the design and evolution of mechanical and cooling systems as Fluidstack scales to multiple gigawatts.Develop and maintain modular mechanical templates that enable rapid, repeatable global deployment.Serve as the technical interface between internal teams and external consultants, keeping designs aligned with Fluidstack's high-density cooling and power requirements.Build supply-chain-aware solutions so designs integrate cleanly and deploy fast.What We're Looking ForThe 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 mechanical design for data centers or high-density facilities, from concept and modeling through build.You design cooling systems for AI-class density (chilled water, CDUs, direct liquid cooling) and think in modular, repeatable templates.You manage external consultants and act as the...
