Mechanical Engineer

Fluidstack Job OpportunityWe 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 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 Modular TeamThe Modular team turns data center capacity into a manufactured product: modules engineered, built, and tested on a production line, then shipped to site ready to energize.Examples of key problems the team is working on:Take modular data center designs from released drawings through first article to rate production on the Phoenix manufacturing lineEngineer cooling, piping, and airflow systems that build clean at station, pass pressure test the first time, and hold up in the fieldClose the loop between the factory floor and design so every build issue gets killed in the drawing, not patched unit by unitCompress the cycle from design revision to line implementation without losing configuration controlRole ScopeOwn the mechanical systems of the modular product on the line, cooling, piping, and airflow, from released drawings through rate productionLive on the Phoenix manufacturing floor: walk the line daily, catch piping and assembly issues at the station where they happen, and disposition them on the spotRun first-article reviews, fit checks, and pressure tests in person as units come down the lineAnswer mechanical RFIs same-day from the floor, and engineer the fix into the next revision rather than leaving it as a one-off deviationClose the loop to design: feed what the line learns back into drawings, tolerances, and the BOM so the same issue never builds twiceWhat 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 engineered mechanical systems for complex physical products or modular construction hands-on, not from a deskYou've worked on a shop floor or production line, and dispositioning a nonconformance in the moment is familiar work, not an escalationYou've supported production launches of your own designs and stayed with them through the problems that only show up at rateYour drawings build clean: fabricators rarely call, and when they do, you fix the drawingYou've run first-article builds and pressure tests personally, and when something failed, you traced it to the drawing or the process rather than reworking units one at a timeYou iterate fast without losing configuration control: every fix lands in a controlled revision, and the line always knows which one it's buildingBonus: liquid cooling depth, piping and pressure testing experience, sheet metal design, or strong DFM instinctsWe are committed to pay equity and transparency.Fluidstack is an Equal Employment Opportunity Employer.
