Network Engineer

Network Engineer OpenAI's Network Engineering team within IT and Security advances the mission of deploying artificial general intelligence (AGI) for the benefit of all by delivering secure, scalable, and resilient network services. We build and operate the connectivity that supports OpenAI's offices, labs, campuses, cloud environments, people, and devices. By combining strong network fundamentals with security, reliability, automation, and user-centered design, we enable impactful AI research, corporate operations, and product innovation. As a Network Engineer at OpenAI, you will design, operate, and continuously improve the global networks that connect our offices, labs, campuses, PoPs, cloud environments, people, and devices. The role spans strategic platform engineering and responsive production operations: you will shape architecture, standards, roadmaps, lifecycle plans, and automation while supporting incidents, escalations, and time-sensitive delivery. Operational signals will inform what we stabilize, simplify, standardize, or automate next. We work backward from user needs, investigate root causes, own outcomes end-to-end, and move quickly without compromising security. We are looking for a versatile engineer who can make pragmatic reliability and security tradeoffs, communicate clearly, and turn recurring operational work into durable platforms, tooling, and standards. You will partner across IT, Security, AppEng, Research, Applied, workplace teams, carriers, and vendors. In this role, you will: Design, implement, and operate secure, scalable enterprise networks across offices, labs, campuses, PoPs, cloud connectivity, and hybrid environments. Set strategic direction for network services through architecture, standards, roadmaps, lifecycle planning, capacity strategy, and measurable reliability outcomes. Own production operations, including on-call, incident response, escalations, and time-sensitive delivery, while protecting user experience, security, and business continuity. Use incident learning, problem management, ticket trends, and telemetry as roadmap inputs, eliminating recurring failure modes through automation, Infrastructure-as-Code, and safer operating standards. Develop dashboards, telemetry, alerts, and health checks that provide actionable visibility into network performance and failure domains. Implement and operate routing, switching, wireless, WAN, Internet edge, firewall, NAC, segmentation, and core network services. Lead network changes, migrations, refreshes, site launches, and service improvements from design through validation and operational handoff. Partner with security and identity teams to apply least privilege, Zero Trust principles, RBAC, device identity, and appropriate access controls. Balance long-term platform improvements with urgent operational priorities through clear ownership, documented decisions, deliberate tradeoffs, and transparent communication. You may be a fit for this role if you have: Hands-on experience designing and operating enterprise networks using platforms such as Cisco IOS, Cisco Meraki, Palo Alto, Arista, or equivalent technologies. Strong routing and switching fundamentals, including BGP, OSPF, VLAN/VRF design, WAN, Internet edge, and high-availability patterns. Production troubleshooting experience across packets, logs, telemetry, configurations, circuits, and physical infrastructure. Experience with network observability using tools and protocols such as SNMP, syslog, NetFlow, packet capture, ELK, Grafana, or comparable platforms. Strong network security fundamentals, including ACLs, firewalls, VPN, 802.1X/NAC, device profiling, segmentation, and least privilege. Ability to automate infrastructure using a modern programming language and tools such as Python, Go, Terraform, Ansible, APIs, Git, and CI/CD. Experience with enterprise wireless and at least one cloud or hybrid connectivity environment. Clear communication, sound operational judgment, and the ability to own outcomes while partnering across technical and business teams You might thrive in this role if you have: Experience shaping a multi-quarter network roadmap while supporting production operations and changing delivery needs. Experience with optical transport and carrier services, including DWDM, wavelengths, dark fiber, DIA, or similar technologies. Experience with cloud and virtual WAN architectures such as Azure Virtual WAN, AWS Transit Gateway, or comparable services. Experience with campus, data center, colocation, or PoP architecture, interconnects, high-availability design, and operational handoff. Experience building internal platforms, self-service workflows, or AI-assisted automation that measurably reduces operational toil. This role is based in San Francisco, CA. We use a hybrid work model of 3 days in the office per week and offer relocation assistance to new employees.
