OpenAI’s Infrastructure Operations team is responsible for the availability, reliability, and operational excellence of one of the world’s largest AI infrastructure networks. The team owns day-to-day operations of production AI networks across Industrial Compute's data centers, working with colocation providers, deployment teams, and hardware vendors to deliver highly available GPU infrastructure for AI training and inference workloads.
We are seeking an Infrastructure Operations Engineer to operate and improve the large-scale Ethernet fabrics that support GPU clusters, storage systems, and management infrastructure. This role combines hands-on production operations with automation, observability, and incident response across a global AI network.
The ideal candidate has experience operating high-availability data center, cloud, AI, or HPC networks and can move comfortably from physical-layer troubleshooting to routing and fabric behavior, change execution, and root-cause analysis. You will partner closely with network architecture, systems engineering, GPU engineering, storage engineering, security, deployment, site operations, service providers, colocation partners, and hardware vendors to raise reliability and reduce operational toil.
Own the operational health, availability, and reliability of production AI network infrastructure across Industrial Compute's data centers.
Monitor, troubleshoot, and resolve network incidents while meeting service-level objectives (SLOs), reducing Mean Time to Detect (MTTD), and minimizing Mean Time to Recovery (MTTR).
Operate and maintain large-scale Ethernet fabrics supporting GPU compute, storage, and management networks.
Execute production network changes, maintenance windows, and capacity expansions with minimal customer impact.
Manage the hardware lifecycle, including switch and optics replacements, RMA coordination, software upgrades, and preventive maintenance.
Support new AI cluster deployments, data center expansions, and infrastructure migrations in partnership with deployment and engineering teams.
Partner with cloud service providers (CSPs), colocation providers, Smart Hands teams, and hardware vendors to maintain production infrastructure.
Perform root-cause analysis (RCA) for production incidents and drive permanent corrective actions that eliminate recurring issues.
Build and maintain monitoring, telemetry, dashboards, and alerting to improve network observability and proactive issue detection.
Develop and improve operational runbooks, playbooks, troubleshooting documentation, and standard operating procedures.
Automate repetitive operational tasks using Python and infrastructure automation frameworks to reduce toil and improve efficiency.
Continuously identify opportunities to improve service reliability, scalability, operational maturity, and engineering efficiency.
Bachelor’s degree in Computer Science, Network Engineering, or a related discipline, or equivalent practical experience.
5+ years of experience operating large-scale data center, cloud, AI, or HPC network infrastructure.
Experience supporting production network environments with high-availability requirements.
Hands-on experience with one or more of the following platforms: Cisco NX-OS, Arista EOS, NVIDIA Spectrum / Cumulus Linux, or Juniper JunOS.
Strong knowledge of Layer 2 and Layer 3 networking, BGP, OSPF, ECMP, MLAG, LACP, VRFs, and VLANs.
Experience troubleshooting physical infrastructure, including fiber optics, transceivers, DAC/AOC cables, and high-speed Ethernet links.
Experience performing software upgrades, hardware maintenance, and production change management.
Excellent analytical and troubleshooting skills, with the ability to communicate technical risk clearly across teams.
Experience operating AI or High-Performance Computing (HPC) network environments.
Experience with NVIDIA AI networking technologies and GPU infrastructure.
Experience supporting RoCE v2 or RDMA-based Ethernet fabrics, with a strong understanding of Priority Flow Control (PFC), Explicit Congestion Notification (ECN), Data Center Quantized Congestion Notification (DCQCN), Quality of Service (QoS), and lossless Ethernet networking.
Experience supporting 100G, 200G, 400G, and 800G Ethernet networks.
Experience with GPU platforms including NVIDIA HGX, DGX, GB200, or equivalent AI infrastructure.
Experience supporting distributed storage environments such as VAST, DDN, or similar technologies.
Experience working with cloud service providers such as AWS, Azure, or Google Cloud, and with third-party colocation providers.
Experience with network monitoring and telemetry technologies, including Prometheus, Grafana, gNMI, streaming telemetry, SNMP, or similar tools.
Experience developing automation using Python, Git, REST APIs, Terraform, or similar automation frameworks.
Participate in a 24x7 on-call rotation supporting mission-critical AI infrastructure.
Support time-sensitive production incidents, maintenance windows, capacity expansions, and network changes with a focus on service availability and minimal customer impact.
This role requires up to 30% travel to data center locations for new turnups and acceptance activities, as needed.
