OpenAI Network Infrastructure Engineer at OpenAI designs, deploys, and operates global WAN infrastructure connecting data centers, cloud providers, and network PoPs. Responsibilities include circuit provisioning, troubleshooting Layer 1-3 issues, and building automation for network operations.

Responsibilities

We are looking for a hands-on Network Infrastructure Engineer to help design, deploy, activate, and operate OpenAI's global wide area network (WAN) infrastructure.
We're looking for engineers who enjoy working close to the infrastructure, thrive on solving difficult networking problems, and bring an automation-first mindset to scaling network operations.
Design, deploy, and support WAN infrastructure across data centers, network PoPs, and cloud connectivity environments.
Own the end-to-end activation and turn-up of network circuits, working directly with fiber carriers and cloud service providers to establish and validate connectivity.
Troubleshoot complex network issues across physical, Layer 2, and Layer 3 infrastructure, including optical signal problems, FEC errors, routing issues, and connectivity failures.
Diagnose and isolate network failures across carrier, cloud provider, and internal infrastructure boundaries, driving issues through resolution.
Contribute to physical network infrastructure design, including port mappings, fiber and cable layouts, optical distribution frames (ODFs), and connectivity planning.
Monitor network health, circuit utilization, and performance to proactively identify capacity constraints and reliability risks.
Build automation and tooling to streamline network provisioning, deployment validation, troubleshooting, and operational workflows.
Collaborate with network engineering, data center infrastructure, and external service providers to support the expansion of OpenAI's global backbone.
Participate in an on-call rotation to maintain the reliability and availability of critical network infrastructure.
