About the role

Meta is seeking a Staff Software Engineer to design, build, and operate software systems that underpin Meta's global network fabric, spanning data center interconnects, edge services, traffic engineering, and network automation. The role involves leading development of scalable, high-reliability software for hyperscale network infrastructure, collaborating with network engineers, hardware teams, and platform partners to deliver production systems that keep Meta's network fast and efficient.

Responsibilities

  • Architect and lead delivery of Meta Compute’s cloud-native host networking platform, owning end-to-end technical direction from design through production rollout
  • Build/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 enforcement
  • Drive time-to-market execution: define milestones, de-risk key technical choices early and deliver iterative production increments
  • Lead broad cross-functional alignment across compute, storage, platform, security, and hardware/fabric partners—owning interfaces/contracts and end-to-end outcomes
  • Leverage and influence open-source ecosystems: evaluate open-source building blocks, contribute improvements where needed, and ensure Meta’s solution is maintainable and operable long-term

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
