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

  • 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.

The Controls Team

Examples of key problems the team is working on

  • Deliver the controls behind 50GW+ of data centers this decade.

  • Own real-time load control and MEP and behind-the-meter integration.

  • Automate Level 4 and Level 5 commissioning.

  • Drive autonomous, robotic deployment.

Role Scope

  • Create template controls designs for our fully modular data center builds, so one validated design set deploys across every site instead of being redrawn project by project.

  • Write sequences of operations that define how the mechanical and electrical systems run, and hand them to the programming team as the source of truth for the code.

  • Build the standard points lists and bills of materials that lock the instrumentation, IO, and controls hardware every modular build draws from.

  • Own the Division 25 integrated automation specification end to end, keeping it current as equipment, vendors, and site designs change.

  • Coordinate the controls design across the mechanical, electrical, and commissioning teams so it matches the equipment it will run and the tests it has to pass.

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 produced controls design packages, drawings, points lists, or specifications, that a contractor or programmer built from without coming back with a list of questions.

  • You’ve written sequences of operations for mechanical or electrical systems and seen them implemented in real controllers, so you know where a vague SOO breaks down in code.

  • You’ve authored or owned a Division 25 integrated automation specification, or an equivalent controls spec, and kept it accurate across multiple projects.

  • You’ve built standard points lists and BOMs, and you know how a wrong point count or a mis-specified device shows up as a change order months later.

  • You design for repeatability, turning one-off engineering into templates that get reused rather than redrawing every project from scratch.

  • You catch the coordination gaps between mechanical, electrical, and controls scopes before they reach the field.

  • Bonus: Data center mechanical and electrical systems (chiller plants, CRAH/CRAC, fan wall units, switchgear). Modular or productized build delivery. BMS and SCADA platforms over BACnet and Modbus. CSI MasterFormat and Division 25 spec writing. Points list and IO schedule tooling.


Compensation: $200,000 - $250,000 per year, depending on experience, skills, qualifications, and location. Offers equity in the form of stock options.

We are committed to pay equity and transparency.
