Requirements

• Deep Bazel experience as an owner: custom rules, toolchains, and target graph design in a large repository.
• Experience migrating a real codebase onto Bazel, including the long tail.
• Hands-on experience deploying and operating remote caching or remote execution, self-hosted or vendor-provided.
• Experience with hermetic, reproducible, and observable builds, including custom toolchains.
• Strong knowledge of C++, Rust, Python, and container image builds.
• Persistence in debugging non-reproducible builds and unexplained cache misses to root cause.
• A track record of partnering with other teams to understand their needs and spread best practices.
• A pragmatic bias toward incremental migration that keeps people productive.

Nice To Haves

• Experience migrating test suites to Bazel.
• Kubernetes-based executor pools.
• Embedded or firmware cross-compilation. Firmware is not in Bazel today, and you would help decide whether it should be.
• Open source contributions to the Bazel ecosystem.

Responsibilities

• Complete the Bazel migration, including the hardest remaining components.
• Migrate the test suite to Bazel, with correct tagging and sharding, and route hardware-dependent tests to executors that have the hardware.
• Design, deploy, and operate remote execution in production.
• Build hermetic toolchains and reproducible builds across developer machines, CI, and hardware-attached runners.
• Raise cache hit rate to target and build trust in the cache, so no one runs a clean build "to be safe."
• Establish a build-time baseline in your first quarter, then reduce median incremental build time and CI critical path against it.
• Evolve the CI/CD system to keep pace with agent-assisted development.
• Raise the standard of Bazel usage across teams by making the correct path the easy one and sharing best practices.
