Build and operate the production network infrastructure connecting all of Airbnb's services
Airbnb's Networking team, within Cloud Infrastructure, owns the company's entire production network — traffic proxies, load balancers, service mesh, VPC/backbone, cross-region connectivity, and network security/monitoring. This engineer will work on cloud-native networking from Layer 3 to Layer 7, contributing to service mesh (Istio), cross-region gateways, and multi-region network architecture on public clouds. Requires 2+ years of relevant software development experience plus public cloud networking expertise (AWS/GCP/Azure, VPC, Security Groups, PrivateLink) and comfort being on-call for production infrastructure.
