Our network infrastructure teams are responsible for developing, deploying, and operating this complex system, covering the entire network lifecycle from hardware development to operation. We're seeking software engineers to join our teams and help build scalable distributed systems, develop innovative solutions to our challenges, and ship them into production. As part of our network engineering teams, you'll have the opportunity to work on cutting-edge switching technology, collaborate with engineers, and contribute to the development of Meta's hyper-scale network infrastructure.Responsibilities\nYour contributions will affect a massive fleet of switches powering both application and AI workloads Design, develop, validate, and deploy control-plane and dataplane software for network switches (Meta's network switch OS), for Meta's data center front-end, AI backend, and backbone networks Partner with switch ASIC and system vendors on SDK integration, new feature development and platform bring-up Engage with network-engineering, routing infrastructure, host networking, transport teams to align on goals, lead integration efforts, and drive continuous development Debug complex system-level issues and lead performance tuning exercises to optimize control-plane and dataplane performance Partner with network operations and deployment teams for fleet-wide rollouts and incident response Develop and automate test suites for the CI/CD framework and various components in collaboration with test infra teams\nQualifications\nBachelor's degree in Computer Science, Computer Engineering, relevant technical field, or equivalent practical experience 7+ years software development experience in industry settings or PhD with 4+ years of experience 3+ years relevant experience with network devices and products (routers, switches, adapters, load balancers) and an understanding of network routing protocols in industry settings Proficiency in C/C++ and at least one scripting language (Python/Shell Scripting) Experience with developing and automating test suites Experience collaborating with cross-functional teams (e.g., hardware, operations, test infrastructure) to define requirements and deliver integrated solutions Experience with stream processing or time-series data pipelines for high-volume network telemetry Experience with the design and implementation of software for high-speed network processing (e.g., Layer 2, Layer 3, MPLS, SRv6, VxLAN, ACLs, QoS, RoCEv2, Mirroring, SAI) Experience with intent-based network management systems Experience with network devices (routers, switches, load balancers) and an understanding of network routing protocols Experience with software-defined networking (SDN), network operating systems, or network device APIs such as OpenConfig or
