The opportunity
The compute infrastructure team runs the GPU fleet and large-scale compute clusters that serve the models backing ChatGPT and the API, while also supporting training workloads for our next generation models. We operate a large, modern GPU fleet and provide a unified platform for…
What you'll do
Own Layer 1 activation and restoration for carrier circuits, dark fiber,: wavelengths, Ethernet handoffs, and dedicated cloud interconnects across data centers and points of presence.
Reconcile complete A-side/Z-side as-builts: circuit IDs, LOAs/CFAs, carrier demarcations, MMR/ODF/MDF and patch-panel positions, fiber pairs, cross-connects, optics, and device ports.
Investigate no-light, low-light, wrong-port, link-flap, and error-rate issues: across providers and CSPs; isolate continuity, dirty connectors, polarity, incorrect patching, incompatible optics or media, wavelength/power-budget problems, breakout, speed, and FEC/PCS mismatches.
Guide remote hands, carrier technicians, CSP operations, and colocation teams: through targeted inspection/cleaning, VFL, optical power, OTDR/OLTS, approved loopback, and per-lane DOM/DDM tests.
Verify service acceptance on both sides: correct circuit and port, admin/operational state, compatible optics, light levels, speed/FEC, clean counters, stable link, and Layer 2/3 handoff readiness.
Own tickets and troubleshooting bridges through resolution; identify the: blocker and A-side/Z-side owner, drive follow-ups, escalate with evidence, and prevent premature closure.
What they're looking for
- Execute smart-hands and change work safely: name the exact circuit, port, and fiber pair; protect adjacent live services; get approval before intrusive tests, repatches, shutdowns, or loopbacks; and maintain rollback.
- Deliver complete production handoffs with verified mappings, provider/CSP: references, test results, interface evidence, incident history, risks, and clear ownership; improve runbooks and prevent repeat faults.
- Automate the full circuit-bring-up lifecycle: structure circuit, port, and patch-panel data; ingest telemetry and provider tickets; generate LLM-assisted diagnostics and technician-ready instructions; track ownership and evidence; and preserve explicit human approval for intrusive work.
- Have 3+ years of hands-on network operations, carrier activation, data-center: network deployment, field engineering, optical transport, or related infrastructure experience; equivalent practical experience is valued.
