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. 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.

How We Operate

• Be a barrel. Full autonomy. Own things end to end, take on scope without being asked, no permission required to operate outside your core role.

• Insane urgency. We drive everything forward as fast as possible.

• Reason from 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.

• Build something that actually matters. If you're going to spend your time, spend it on something that matters to the world.

Role Scope

• Run a fabrication shift: crew, safety, quality, and output owned hour by hour.

• Lead operators and welders directly: assignments, coaching, and accountability on the floor.

• Execute the daily plan and upscale misses with causes, not excuses.

• Enforce the standards: work instructions followed, lockout-tagout respected, 5S held.

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 supervised fabrication or welding crews in production.

• You've held a shift to takt and communicated clearly when it broke.

• Your crews are safe on your watch and can say why.

• You coach on the spot and document when it matters.

• You run a clean, organized area by habit.

• Bonus: Steel and structural fabrication. Startup ramps. Lean daily management. Bilingual English and Spanish.

We are committed to pay equity and transparency.
