Note: The job is a remote job and is open to candidates in USA. Fluidstack is a company that builds the compute, data centers, and power for artificial superintelligence. They are seeking a DC Infrastructure Architect responsible for designing and implementing scalable, resilient optical and structured cabling solutions for hyper-scale data centers.
Responsibilities
- Translate logical network topologies into a scalable, resilient, and cost-optimized optical and structured cabling design for hyper-scale data centers
- Own the end-to-end physical implementation of the data center network (DCN), including fiber plant architecture, transceiver planning, and integration with structured cabling ecosystems
- Break down 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)
- Define cassette types (MTP/MPO Base-8/12/16), trunk counts, and structured cabling hierarchy
- Plan cassette placement within racks, rows, and meet-me-rooms
- Model fiber utilization and overbuild for 2–3 hardware generations
- Select optics (400G/800G DR4, FR4, LR4, SR8, coherent DCI) based on reach and loss budget
- Validate interoperability across vendors and generations
- Maintain loss budget and margin models for every link type
- Define patching architectures (direct MPO vs. breakout vs. mid-span)
- Ensure pathways (ladder racks, underfloor, ODFs) scale with fiber density
- Establish standards for labeling, documentation, and change management
- Build modular designs for pod/rack growth
- Anticipate transition to higher-speed optics (e.g., 400G → 800G → 1.6T)
- Integrate with DCIM (NetBox, custom tools) to track strands, ports, and patching
Skills
- Proven experience designing hyperscale or cloud provider data center networks (1000+ racks, 100K+ fiber strands)
- Expert in structured cabling systems (Corning, Panduit, CommScope) and MPO/MTP ecosystems
- Deep knowledge of optical standards (IEEE 802.3, OIF) and transceiver technologies (400G/800G DR4, FR4, LR4, SR8)
- Strong grasp of fiber loss budgets, dispersion, and testing methodologies (OTDR, insertion loss, polarity verification)
- Experience integrating designs into DCIM tools (NetBox, Remedy, custom hyperscaler equivalents)
Benefits
- Competitive total compensation package (salary + equity).
- Retirement or pension plan, in line with local norms.
- Health, dental, and vision insurance.
- Generous PTO policy, in line with local norms.
