Lab 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!

How We Operate

• Be a barrel. Full autonomy. Own things end to end, take on scope without being asked, no permission required to operate outside your core role.

• Insane urgency. We drive everything forward as fast as possible.

• Reason from 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.

• Build something that actually matters. If you're going to spend your time, spend it on something that matters to the world.

The Fluidstack Labs Team

Examples of key problems the team is working on

• Qualify the hardware the frontier runs on before it runs anywhere else. First samples of next-generation accelerators, switches, storage, and liquid cooling land here, and leave as production-ready platforms with runbooks the whole fleet inherits.

• Compress silicon-to-production to weeks. The lab closes the gap between vendor sample and customer-ready gigawatt infrastructure, and every week cut here pulls the entire deployment curve forward.

• Run the lab like a production site. Provisioning, telemetry, demand management, and liquid cooling mirror production architecture exactly, so a qualification pass in the lab is a deployment guarantee in the field.

• Prove the power envelope nobody else will touch. Dynamic demand management lets AI compute deploy beyond nominal electrical capacity, and the lab validates the full detection-to-shutdown response chain that makes it safe.

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

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 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.

We are committed to pay equity and transparency.
