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.

Qualifications:

Bachelor's degree in Computer Science, Computer Engineering, relevant technical field, or equivalent practical experience 10+ years of experience in software development for networking or infrastructure systems, or a PhD with 4+ years of experience in a relevant technical area 4+ 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 suites Demonstrated experience working across disciplines to align on technical decisions and deliver integrated solutions 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 requirements Expertise in high-performance networking frameworks and techniques such as DPDK, eBPF/XDP, AF\_XDP, io\_uring, kernel bypass, zero-copy I/O, and RDMA/RoCEv2 Direct experience with DPU SoC/SmartNIC platforms Experience building or contributing to Kubernetes operators, controllers, or device plugins that manage hardware-accelerated networking or storage resources Familiarity with Linux networking internals such as netdev subsystem, TC/iptables/nftables, network namespace isolation, traffic shaping, and kernel driver development Experience in hyperscale or cloud-provider environments
