Data Center Infrastructure Architecture, Lead

Job Overview

Fluidstack is seeking a Data Center Infrastructure Architecture, Lead to own the reference architecture for the datacenter cable plant across ISP and OSP, from fiber counts and pathway design to the stamped design deployed at every site. The ideal candidate will design structured cabling and connectivity for the densest GPU fabrics ever built, at 800G today and 1.6T next, and turn a bespoke, months-long cable plant design into a validated reference architecture that a team can deploy across tens of gigawatts of capacity.

Role Scope

• Own the reference architecture for the datacenter cable plant across ISP and OSP, from fiber counts and pathway design to the stamped design deployed at every site.
• Design structured cabling and connectivity for the densest GPU fabrics ever built, at 800G today and 1.6T next.
• Turn a bespoke, months-long cable plant design into a validated reference architecture that a team can deploy across tens of gigawatts of capacity.
• Spec the physical layer to survive multiple GPU generations, each of which rewrites the density, optics, and pathway math.
• Set the standards and lead the engineers and vendors who take the architecture from design to installed and tested across many concurrent builds.

What We're Looking For

We are looking for someone who has architected the physical cable plant across ISP, OSP, structured cabling, and pathways for large datacenter or campus builds, not just designed a single room. The ideal candidate will have designed for high-density, high-speed fabrics at 400G, 800G, or beyond and made the optics, fiber-count, and pathway calls themselves. They will have turned a one-off design into a repeatable reference architecture that others deployed without them in the room, and have specced infrastructure that had to survive multiple hardware generations, and it did. They will have led engineers and coordinated vendors and contractors to take a design from paper to installed and tested at scale.

About Fluidstack

Fluidstack exists to make humanity more free. We are 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.

How We Operate

• Extreme ownership. Full autonomy. Own things end to end often taking on scope outside your core role without being asked to get things done.
• Velocity. We drive everything forward as fast as possible.
• 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.
