About the job

Join Fluidstack: Pioneering the Future of Intelligence

At Fluidstack, we are dedicated to constructing the framework for abundant intelligence. Collaborating with elite AI laboratories, governmental bodies, and enterprises—including Mistral, Poolside, Black Forest Labs, and Meta—we aim to provide computing resources at unparalleled speeds.

Our mission is to expedite the realization of Artificial General Intelligence (AGI). Our team is driven, passionate, and committed to delivering top-tier infrastructure solutions. We view our clients' success as our own, taking immense pride in the systems we create and the trust we cultivate. If you are purpose-driven, excellence-obsessed, and eager to work diligently to advance the future of intelligence, we invite you to join us in shaping what comes next.

Role Overview

As a Data Center Infrastructure Architect (Optical), you will play a crucial role in transforming logical network designs into scalable, resilient, and cost-effective optical and structured cabling frameworks tailored for hyper-scale data centers. This position encompasses the complete physical execution of the data center network (DCN), including fiber plant architecture, transceiver planning, and integration with structured cabling systems.

Key Responsibilities

  • Logical / Physical Mapping:
    • Deconstruct DCN logical port maps (TOR, spine, super-spine, DCI) into physical cross-connect and patching schedules.
    • Automate port-to-fiber mapping at scale (100K+ ports per site).
  • Fiber Plant Design:
    • Specify cassette types (MTP/MPO Base-8/12/16), trunk counts, and structured cabling hierarchy.
    • Plan cassette positioning within racks, rows, and meet-me-rooms.
    • Model fiber utilization and overbuild for 2–3 hardware generations.
  • Optics / Transceiver Planning:
    • Choose optics (400G/800G DR4, FR4, LR4, SR8, coherent DCI) based on reach and loss budget.
    • Ensure interoperability across various vendors and product generations.
    • Maintain loss budget and margin models for every link type.
  • Structured Cabling & Physical Implementation:
    • Define patching architectures (direct MPO vs. breakout vs. mid-span).
    • Ensure pathways (ladder racks, underfloor, ODFs) are designed to scale with fiber density.
    • Establish standards for installation practices and documentation.
