Job description

Meta's network infrastructure powers some of the world's largest and most complex distributed systems, supporting billions of users across social media, AI, and immersive computing platforms. We are seeking a Staff Software Engineer to help design, build, and operate the software systems that underpin Meta's global network fabric — spanning data center interconnects, edge services, traffic engineering, and network automation. In this role, you will lead the development of scalable, high-reliability software that manages and optimizes network infrastructure at hyperscale, working closely with network engineers, hardware teams, and platform partners to deliver production systems that keep Meta's network fast, resilient, and efficient.Software Engineer, Network Infrastructure Responsibilities:Architect and lead delivery of Meta Compute’s cloud-native host networking platform, owning end-to-end technical direction from design through production rolloutBuild/modernize Kubernetes networking features integrated with Meta’s host networking stack (e.g., dataplane integration, operability, scaling characteristics)Design and implement core networking primitives: network virtualization, load balancing/service connectivity, and distributed firewalling/policy enforcementDrive time-to-market execution: define milestones, de-risk key technical choices early and deliver iterative production incrementsLead broad cross-functional alignment across compute, storage, platform, security, and hardware/fabric partners—owning interfaces/contracts and end-to-end outcomesLeverage and influence open-source ecosystems: evaluate open-source building blocks, contribute improvements where needed, and ensure Meta’s solution is maintainable and operable long-termMinimum Qualifications:Bachelor's degree in Computer Science, Computer Engineering, relevant technical field, or equivalent practical experience10+ years of experience in software development for networking or infrastructure systems, or a PhD with 4+ years of experience in a relevant technical area4+ years proven experience designing and shipping networking dataplane/control-plane systems in production (e.g., host networking, L4/L7 load balancing, NAT/conntrack, firewalls/policy, network virtualization)Hands-on Kubernetes networking experience in production (e.g., CNI, Services, NetworkPolicy/policy models, service connectivity/load balancing integration)Proficiency in C/C++ and at least one scripting language (Python/Shell scripting)Experience with developing and automating test suitesDemonstrated experience working across disciplines to align on technical decisions and deliver integrated solutionsPreferred Qualifications:Experience collaborating closely with hardware and ASIC design teams, contributing to hardware specifications, co-designing hardware-software interfaces, and influencing silicon feature sets based on software requirementsExpertise in high-performance networking frameworks and techniques such as DPDK, eBPF/XDP, AF\\_XDP, io\\_uring, kernel bypass, zero-copy I/O, and RDMA/RoCEv2Direct experience with DPU SoC/SmartNIC platformsExperience building or contributing to Kubernetes operators, controllers, or device plugins that manage hardware-accelerated networking or storage resourcesFamiliarity with Linux networking internals such as netdev subsystem, TC/iptables/nftables, network namespace isolation, traffic shaping, and kernel driver developmentExperience in hyperscale or cloud-provider environmentsAbout Meta:Meta builds technologies that help people connect, find communities, and grow businesses. When Facebook launched in 2004, it changed the way people connect. Apps like Messenger, Instagram and WhatsApp further empowered billions around the world.
