Job description

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. 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.

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.

Examples of Key Problems the Team Is Working On

• Supply tens of gigawatts of compute, the largest build out of compute in history. Qualify and dual‑source across every critical equipment category, with lead‑time and capacity thresholds tied directly to the forward build pipeline.
• Make the supply chain the reason we build faster than anyone. Our modular build redefines speed in this industry, and it lives or dies on the supply chain. Keep procurement permanently off the critical path so schedule compression stays our advantage, not our constraint.
• Build the most accurate supply chain prediction modelling that exists. Use the frontier of AI to forecast lead times, demand, and disruption with a precision the industry has never had, and turn that foresight into a structural edge.

Role Scope

• Own the steel category: structural steel and fabricated assemblies feeding the modular manufacturing line and site builds.
• Source fabrication capacity across regional shops so throughput scales with the build plan, not with one shop's backlog.
• Negotiate raw material and fabrication pricing with mechanisms that survive commodity swings.
• Qualify fabricators on quality and capacity, and manage the load balancing across them weekly.

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 sourced structural steel or fabricated steel assemblies at industrial volume.
• You understand fabrication economics: material, labor, coatings, and freight, and where each shop makes its margin.
• You've qualified fabrication shops and caught the capacity overstatements in their pitch.
• You manage commodity exposure with indexing or hedging rather than hoping.
• Bonus: AISC‑certified fabrication networks. Modular construction. Weld quality programs. Logistics for oversize loads.

We are committed to pay equity and transparency.
