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 Data Center Design Team

Examples of key problems the team is working on

• Lead the design, development, and execution of 50GW+ of data centers this decade.
• Drive the next generation of liquid cooling and electrical distribution systems.
• Develop and scale first-of-a-kind modular data centers.
• Influence behind-the-meter designs and planning for multi-GW campuses.

Role Scope

• Own the fire protection scope of design packages from concept through construction documents across the data center portfolio, designing and specifying VESDA and addressable fire alarm, pre-action sprinkler, wet pipe, and clean agent suppression systems.
• Serve as Fluidstack’s primary point of contact with local fire marshals and AHJs on every site, running plan reviews and negotiating code-compliant equivalencies on non-standard designs so permitting stays off the critical path.
• Develop campus-level fire suppression strategy, coordinating water supply, distribution, and system redundancy across multiple buildings and phases of a build-out.
• Review and approve fire protection submittals and shop drawings from EPC and equipment vendors, and validate third-party consultant designs for code compliance and consistency with Fluidstack standards before they advance to construction.
• Support commissioning of fire detection and suppression systems with the Commissioning Agent, resolving test failures before sign-off, and provide fire protection input on capacity additions, retrofits, and incident-driven remediation on live sites.

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 personally designed, specified, and stood up fire detection and suppression systems for mission-critical, industrial, or large commercial facilities, not just reviewed someone else’s plans.
• You hold a PE license in Fire Protection Engineering, or NICET Level III/IV certification in Fire Alarm Systems and Water-Based Systems.
• You’ve negotiated code-compliant alternatives directly with fire marshals and AHJs on non-standard designs, and you know how to keep permitting off the critical path.
• You have thorough working knowledge of NFPA 75, 76, and 2001, and FM Global’s data center loss prevention requirements, and you translate that code into decisions EPCs and operations teams can act on.
• You coordinate fire protection design with electrical, mechanical, and controls engineering so life safety systems integrate cleanly into the rest of the building, not bolted on at the end.
• You write clearly enough that a system narrative, hydraulic calculation, or piece of AHJ correspondence still reads as the source of truth for a site years after you wrote it.
• Bonus: FM-200 and Novec 1230 clean agent systems in data center environments. Multiple state or municipal AHJ jurisdictions. Hyp…
