About Fluidstack

Technology is the most important tool humans have found for improving the human condition, but it is not a default good. It is a lever for ideology.

Today the most powerful technology in history is being built: machines that solve problems better than humans can. The most important mission of our generation is to imbue AI with democratic values: error-correcting institutions, freedom of speech, individual liberties. AI trains and runs on massive compute clusters. Whichever ideology builds the infrastructure the fastest is the ideology that will endure. Democracy is delicate and won't survive this technology by default.

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.
