About Fluidstack

Technology is the most important tool humans have found for improving the human condition, but it is not a default good. It is a lever for ideology.

Today the most powerful technology in history is being built: machines that solve problems better than humans can. The most important mission of our generation is to imbue AI with democratic values: error-correcting institutions, freedom of speech, individual liberties. AI trains and runs on massive compute clusters. Whichever ideology builds the infrastructure the fastest is the ideology that will endure. Democracy is delicate and won't survive this technology by default.

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.

The Commissioning Team

Examples of key problems the team is working on

  • Stand up the commissioning program for 10s to 100s of GWs of capacity this decade.

  • Run commissioning and QA-QC for first-of-a-kind modular data centers.

  • Automate Level 4 and Level 5 commissioning.

Role Scope

  • Commission mechanical systems for gigawatt-scale data centers: chilled water plants, CDUs, liquid loops, and airside systems from Level 2 through Level 5.

  • Write and execute test scripts that prove capacity, redundancy, and failure response, not just that equipment turns on.

  • Run functional and integrated systems tests with controls and electrical so the building performs as one system.

  • Feed test findings back into the standard design so the next site commissions faster.

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 commissioned mechanical plant on mission critical facilities through integrated systems testing.

  • You read P&IDs and controls drawings fluently.

  • You troubleshoot live systems with vendors watching and a deadline standing behind you.

  • Bonus: Liquid cooling and direct-to-chip systems. CxA credential. Modular data centers. Test and balance oversight.
