Shape the next-gen build system (Bazel) and CI/CD experience for every backend developer at Airbnb
Airbnb's Service Tools team owns the end-to-end developer lifecycle for backend service owners — build systems, integration testing, and deployment tooling — for the company's largest developer cohort. This role calls for 6+ years of industry experience, deep JVM and large-monorepo exposure, and hands-on build-system work, ideally with Bazel, to move core metrics like developer velocity and debuggability.
