Software Engineer - HostCloud Networking

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 dataplanehost 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 balancingservice connectivity, and distributed firewallpolicy 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.
