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.

Role Scope

• Own reliability engineering for the reference design: availability modeled, weak points found, and fixes engineered before deployment.

• Build the RAM models: failure rates, redundancy, and maintainability quantified per configuration.

• Run FMEAs across disciplines: failure modes cataloged and designed out with the engineering teams.

• Close the loop with the fleet: field failures fed back into models and design changes.

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 done reliability engineering for infrastructure, energy, or complex hardware.

• You've built availability models decision-makers used.

• You've led cross-discipline FMEAs that changed designs.

• You mine field data for the truth about failure rates.

• You argue redundancy trade-offs in dollars and nines.

• Bonus: Data center topologies. RAM modeling software. Weibull analysis. Maintenance strategy design.

We are committed to pay equity and transparency.
