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.

We hire people who care deeply about this problem space. If that is you, please apply!

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

  • Engineer demand management controls: the logic that flexes gigawatts of load against grid signals and price.
  • Build control strategies coordinating IT load, cooling, and behind-the-meter generation without touching an SLA.
  • Integrate with markets and utilities: signals in, verified response out, settlement-grade data behind it.
  • Prove strategies in simulation, then deploy them across the fleet.

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 engineered controls for energy systems: demand response, microgrids, or industrial load management.
  • You've built control logic that acted on real load and kept its constraints.
  • You understand power systems enough to know what not to automate.
  • You've integrated with utility or market signals.
  • You validate in simulation before the field, every time.
  • Bonus: Data center power and cooling. BESS controls. ISO and RTO market mechanics. Optimization methods.

We are committed to pay equity and transparency.
