Network Operations Engineer, WAN Infrastructure & Circuit Bring-Up

About the Team

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 other OpenAI teams to seamlessly run production Applied AI and Research training workloads.

We seek to learn from deployment and distribute the benefits of AI, while ensuring that this powerful tool is used responsibly and safely. Safety is more important to us than unfettered growth.

About the Role

Own the hands-on work that brings WAN, fiber, carrier, and cloud-interconnect circuits into service. Partner directly with network engineers, fiber providers, cloud service providers, colocation teams, and technicians to take each connection from ordered and patched to verified, stable, and ready for handoff.

This is an execution-focused Layer 1 troubleshooting and circuit bring-up role. Reconcile the physical path and A-side/Z-side assignments, direct targeted debugging, and stay with every owner until the correct port is green and ready for handoff.

The right person enjoys detailed technical work: patch-panel mappings, fiber pairs, transmit/receive polarity, optics, light levels, provider demarcations, port assignments, change tickets, and evidence-backed service handoffs.

In this role, you will:

• 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.

• 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.

You might thrive in this role if you have:

• 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.

• Can trace an end-to-end circuit across cross-connects, fiber pairs, patch panels, carrier demarcations, optics, and both A-side and Z-side device ports.

• Troubleshoot optical faults using inspection/cleaning tools, optical power meters, VFL, OLTS/OTDR evidence, DOM/DDM, interface status, and provider test results.

• Understand single-mode/multimode fiber, LC and MPO/MTP connectors, duplex polarity, TX/RX paths, wavelength and power budgets, and 100G/400G/800G optics.

• Have worked with carriers, colocation providers, remote hands, AWS Direct Connect, Azure ExpressRoute, or Google Cloud Interconnect, and persist through multi-party ownership gaps.
