They design and operate the systems that provide predictable, high-throughput, low-latency connectivity across some of the world’s most advanced AI infrastructure.\nAbout the Role\nWe’re looking for engineers to help build and operate the networking foundation behind OpenAI’s frontier AI systems.\nDepending on your background and area of focus, you may work across host networking, datacenter fabrics, or global WAN infrastructure. The problems span low-level systems software, distributed infrastructure, protocol readiness, observability, performance engineering, automation, and large-scale network operations.\nYou’ll work on systems where microseconds of latency, tail performance, and network reliability directly impact model training efficiency and production serving performance.\nThis role is ideal for engineers who enjoy operating close to the hardware/software boundary and solving performance-critical infrastructure problems at massive scale.\nIn this role, you will:\nDesign, build, and operate networking systems that support large-scale AI training and inference infrastructure\n\nImprove performance, reliability, and scalability across host networking, datacenter fabrics, and WAN systems\n\nDevelop automation for provisioning, configuration management, validation, upgrades, and lifecycle management of networking infrastructure\n\nBuild tooling and observability systems for network health, performance analysis, debugging, and automated remediation\n\nOptimize network performance across technologies such as RDMA, RoCE, InfiniBand, Ethernet, and high-performance GPU interconnects\n\nDefine and operationalize networking protocols, readiness criteria, and continuous validation systems\n\nPartner closely with compute, storage, hardware, and infrastructure teams to ensure networking scales predictably with fleet growth\n\nContribute to architecture decisions around topology design, capacity planning, failure domains, and network reliability\n\nDiagnose complex distributed systems and networking issues across large heterogeneous compute environments\n\nYou might thrive in this role if you:\nHave experience building or operating large-scale networking or distributed systems infrastructure\n\nAre comfortable working close to the hardware/software boundary\n\nHave experience with Linux networking, kernel systems, NICs, RDMA, or performance-sensitive infrastructure software\n\nHave worked with high-performance networking technologies such as InfiniBand, RoCE, DPDK, or large-scale Ethernet fabrics\n\nHave experience with datacenter networking, WAN systems, or host networking stacks\n\nEnjoy debugging complex systems and performance bottlenecks across multiple layers of the stack\n\nAre comfortable writing production software in languages such as C++, Python, or Go\n\nHave strong systems fundamentals across networking, operating systems, distributed systems, or infrastructure engineering\n\nAre motivated by building infrastructure that directly accelerates frontier AI research and deployment\n\nAbout OpenAI\nOpenAI is an AI research and deployment company dedicated to ensuring that general-purpose artificial intelligence benefits all of humanity. We push the boundaries of the capabilities of AI systems and seek to safely deploy them to the world through our products. AI is an extremely powerful tool that must be created with safety and human needs at its core, and to achieve our mission, we must encompass and value the many different perspectives, voices, and experiences that form the full spectrum of humanity.\nWe are an equal opportunity employer, and we do not discriminate on the basis of race, religion, color, national origin, sex, sexual orientation, age, veteran status, disability, genetic information, or other applicable legally protected characteristic.\nFor additional information, please see OpenAI’s Affirmative Action and Equal Employment Opportunity Policy Statement.\nBackground checks for applicants will be administered in accordance with applicable law, and qualified applicants with arrest or conviction records will be considered for employment consistent with those laws, including the San Francisco Fair Chance Ordinance, the Los Angeles County Fair Chance Ordinance for Employers, and the California Fair Chance Act, for US-based candidates.
