ICT Infrastructure Architect

About the role

Fluidstack exists to make humanity more free by 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.

How we operate: Be a barrel – full autonomy, own things end to end, take on scope without being asked; insane urgency; reason from first principles; love of the game; build something that actually matters.

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; 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; 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; 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; integrate with DCIM (NetBox, custom tools) to track strands, ports, and patching.
• Design the physical layer AGI is trained on: ISP/OSP cable plants carry hundreds of thousands of fiber terminations per building, rail‑optimized for the densest GPU fabrics ever built, at 800G today and 1.6T next.
• Turn the cable plant from a bespoke months‑long exercise into a stamped reference architecture deployed across 10s to 100s of GWs of capacity, validated once and built everywhere
