Principal Operations Engineer, Reliability

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.

How We Operate

• Extreme ownership
• Velocity
• First principles
• Love of the game

Role Scope

• Own fleet reliability engineering: define availability targets, measure them honestly, and close the gap
• Run root cause analysis on the fleet's worst incidents and drive corrective actions to done across every site
• Build the failure data pipeline, facility and hardware both, that turns incident history into engineering priorities
• Set the maintenance strategy (reliability-centered, condition-based) so the fleet spends effort where the failure data says to

What We're Looking For

• You've owned reliability for critical infrastructure and moved the availability number, not just reported it
• You've led root cause analyses that found the real cause, not the convenient one
• You work fluently with failure data: Weibull, Pareto, and FMEA are tools you actually use, not terms you know
• You get corrective actions closed across teams you don't manage

Bonus

• Data center or power generation reliability
• Liquid cooling systems
• CMMS analytics
• CRE or CMRP certification
