Software Engineer; Technical Leadership - Host Networking Job Seattle area,Washington USA,IT/Tech

Position: Software Engineer (Technical Leadership) - Host Networking

Summary

Meta is investing heavily on the Meta Cloud. As part of this push we want to build a cloud native infrastructure optimized for AI development. The Host Networking team owns the networking stack that runs on the compute platforms at Meta, spanning the software dataplane/host networking platform and select custom hardware components that power connectivity, performance, and security across our fleet.

As part of the Meta Compute Initiative, we’re evolving this foundation to support a cloud-native, Kubernetes-first AI infrastructure—including platform primitives like network virtualization, load balancing/service connectivity, and distributed firewall/policy enforcement—at Meta scale. This is a chance to lead architecture and delivery while influencing a broad cross-functional ecosystem, leveraging (and contributing to) open source where it helps us move faster. We build the platform layer and partner closely with the many application teams that run on top.

Skills

Software Engineer (Technical Leadership) - Host Networking 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
