## 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 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
