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.

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 automated commissioning from the controls side: test sequences written into the control layer itself.
  • Build the functional test library: every device and sequence in the reference design with an automated test to match.
  • Run automated commissioning on live sites: execute, analyze, and disposition failures with the field team.
  • Feed results upstream: design and controls standards fixed where tests keep failing.

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 jobs.ashbyhq.com
  • You've commissioned building or data center control systems hands-on.
  • You've written the test procedures, not just executed them.
  • You program BMS or PLC platforms well enough to embed tests in logic.
  • You analyze trend data to find the failure the point check missed.
  • You've turned repeat findings into upstream fixes.
  • Bonus: L4 and L5 commissioning at scale. Tridium, ALC, Siemens, or PLC platforms. Analytics tooling. Electrical commissioning interface.

We are committed to pay equity and transparency.
