Responsibilities
- Complete the Bazel migration, including the remaining complex components.
- Migrate and shard the test suite in Bazel and route hardware-dependent tests to suitable executors.
- Design, deploy, and operate production remote execution infrastructure.
- Build hermetic toolchains and reproducible builds across developer machines, CI, and hardware-attached runners.
- Improve build-cache hit rates and trust in cached results.
- Establish build-time baselines and reduce median incremental build time and CI critical-path duration.
- Evolve the CI/CD system for agent-assisted development.
- Promote consistent Bazel practices and collaborate with engineering teams on build standards.
Requirements
- Deep ownership experience with Bazel custom rules, toolchains, and target-graph design in a large repository.
- Experience migrating a real codebase onto Bazel, including complex long-tail components.
- Hands-on experience deploying and operating remote caching or remote execution.
- Experience with hermetic, reproducible, and observable builds, including custom toolchains.
- Strong knowledge of C++, Rust, Python, and container image builds.
- Ability to debug non-reproducible builds and unexplained cache misses to root cause.
- Track record of partnering with teams and spreading engineering best practices.
- Pragmatic approach to incremental migration that preserves developer productivity.
- Preferred: experience migrating test suites to Bazel, Kubernetes-based executor pools, embedded or firmware cross-compilation, or open-source contributions to the Bazel ecosystem.
Benefits
- Hybrid work arrangement in Santa Clara, California, with three days per week in the office.
