Principal Operations Engineer, Hardware — Data Center Operations

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!

About the Role

We are seeking a Principal Operations Engineer, Hardware to serve as the most senior technical authority for the operational hardware fleet across our hyperscale AI data center portfolio. AI infrastructure lives and dies on the reliability of the compute itself — this role exists to ensure that the GPU systems, servers, and supporting hardware we deploy at scale are operated, maintained, and continuously improved at the standard the workload demands. You will operate as the technical arm of senior operations leadership in the field — leading site assessments and operational audits, driving the technical readiness of teams ahead of site activation, reviewing hardware platforms and integration designs from an operational lens, and feeding operational learnings back into the hardware engineering, deployment, and supply chain organizations as we shift toward a productized, repeatable build model. You will be a force multiplier across our site hardware leads, deployment teams, and reliability engineers, and the connective tissue between hardware operations, hardware engineering, network, facilities, and customer-facing teams. The ideal candidate has spent a career operating hardware at scale — in hyperscale data centers, large HPC environments, or comparable 24/7 infrastructure — and is equally comfortable diagnosing a stubborn boot failure on the floor, leading a fleet-wide root cause investigation, and pushing back on a vendor on a flawed RMA process. Formal engineering credentials are valued but not required — practical depth, judgment under pressure, the ability to teach, and the discipline to keep critical infrastructure running through change are what define this role.
