Data Center Infrastructure Architect

Fluidstack•Austin, TX

23d•$183,000 - $218,000•Remote

About The Position

Fluidstack is building civilization-scale infrastructure for AI, focusing on delivering massive amounts of compute power faster than anyone else. This role is part of the Infrastructure Team, which is responsible for designing the physical layer that AI is trained on. The team works on high-density GPU fabrics, creating reference architectures for rapid deployment across numerous sites, and designing for future silicon generations. The Data Center Infrastructure Architect will own the end-to-end physical implementation of the data center network, including fiber plant architecture, transceiver planning, and structured cabling integration for hyperscale sites. This involves close collaboration with various teams, breaking down complex logical port maps into physical schedules, defining cabling hierarchy, selecting and validating optics, and owning the ICT Basis of Design and master specifications. The role requires integrating designs with DCIM tools for tracking network assets.

Requirements

Designed hyperscale or cloud-provider data center networks (1000+ racks, 100K+ fiber strands).
Expert in structured cabling systems (Corning, Panduit, CommScope) and MPO/MTP ecosystems.
Knowledge of optical standards (IEEE 802.3, OIF) and transceiver technologies (400G/800G DR4, FR4, LR4, SR8) deeply.
Proficiency in fiber loss budgets, dispersion, and testing methodologies (OTDR, insertion loss, polarity verification).
Experience integrating designs into DCIM tools (NetBox, Remedy, or custom hyperscaler equivalents).

Nice To Haves

RCDD certification.
Coherent DCI.
Multi-generation optics roadmapping.

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.
