ICT Infrastructure Architect

About the role

Fluidstack exists 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.

How we operate: Full autonomy and extreme ownership – own things end to end, often taking on scope outside your core role without being asked. Insane urgency and velocity – 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 – spend your time on something that matters to the world.

Responsibilities

• Own the end-to-end physical implementation of the data center network: fiber plant architecture, transceiver planning, and structured cabling integration for hyperscale sites.
• Collaborate with CSA, MEP, and construction teams on power, cooling, space, pathways, cabinets, and racks, and develop, read, and interpret construction drawings in Bluebeam, ACC, and Procore.
• Break down DCN logical port maps (TOR, spine, super-spine, DCI) into physical cross-connect and patching schedules, and automate port-to-fiber mapping at 100K+ ports per site.
• Define cassette types (MTP/MPO Base-8/12/16), trunk counts, and structured cabling hierarchy, and model fiber utilization and overbuild for two to three hardware generations.
• Select optics (400G/800G DR4, FR4, LR4, SR8, coherent DCI) by reach and loss budget, validate interoperability across vendors and generations, and maintain loss-budget and margin models for every link type.
• Own the ICT Basis of Design, SOPs, and Division 26/27/28/33 master specifications, and integrate with DCIM (NetBox, custom tools) to track strands, ports, and patching.

Requirements

• You've designed hyperscale or cloud-provider data center networks (1000+ racks, 100K+ fiber strands).
• You're expert in structured cabling systems (Corning, Panduit, CommScope) and MPO/MTP ecosystems.
• You know optical standards (IEEE 802.3, OIF) and transceiver technologies (400G/800G DR4, FR4, LR4, SR8) deeply.
• You command fiber loss budgets, dispersion, and testing methodologies (OT
