Data Center Technician, Fluidstack Labs
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!
Role Scope
Own the lab floor: rack-and-stack execution, structured copper and fiber cabling, hardware installs and swaps, and part replacement on first-sample compute, network, and storage platforms, keeping asset records accurate through every change.
Receive and inventory every piece of equipment through the lab, handle RMAs end to end, and document installations and change activity physically and photographically so the record matches the floor.
Provide smart-hands support for remote engineering teams and hardware partners: cabling diagnosis and replacement, component reseats and swaps, console access, and the on-the-floor eyes that unblock a remote debug session.
Support liquid cooling work alongside deployment engineering, including CDU manifold connections and visual leak inspection, with the floor discipline that high-density liquid-cooled racks demand.
Act as first point of contact for facility-floor issues, escalating to the lab's technical leads, and escort vendors and partners during on-site visits while keeping their equipment, access, and confidentiality boundaries clean.
What We're Looking For
- You've deployed and supported server and network hardware in a live data center or hardware lab: racked it, cabled it, fixed it, and kept it running.
- You troubleshoot server hardware deeply: POST, BIOS, PXE, IPMI, BMC, and component-level repair.
- You know network fundamentals (TCP/IP, Ethernet) and hardware (switches, routers, copper and fiber) well enough to diagnose physical-layer faults yourself.
- You work comfortably in Linux for hands-on diagnosis and recovery at the console.
- Asset records, labels, and documentation are habits for you: what's on the floor always matches what's in the system.
- You've worked around unreleased or partner-owned hardware, or you're comfortable doing so, treating what you see and touch as confidential.
- Bonus: GPU server fleets. Hyperscale or high-density AI infrastructure. Liquid-cooled systems. Scripting (Python, Bash). Structured cabling.
Salary & Benefits
- Competitive total compensation package (salary + equity).
- Retirement or pension plan, in line with local norms.
- Health, dental, and vision insurance.
- Generous PTO policy, in line with local norms.
