Fire Protection Engineer, R&D

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 fire protection in the reference design: detection, suppression, and alarm systems for modular units and BTM plants.

• Run the calcs and layouts: hydraulics, coverage, and device placement owned end to end.

• Develop the details that repeat: standardized designs fabricated into modules instead of field-built.

• Support permitting and commissioning: AHJ questions answered, acceptance tests passed.

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 designed fire protection systems for industrial or mission-critical facilities.

• You run your own hydraulic calcs and stand behind them.

• You've taken designs through plan review and acceptance testing.

• You know NFPA 13 and 72 well and look up the rest fast.

• You design for fabrication, not just for the code minimum.

• Bonus: Clean agent and water mist systems. BESS protection (NFPA 855). AutoSPRINK or HydraCAD. NICET or PE track.

We are committed to pay equity and transparency.
