Responsibilities
- Own and evolve Bazel- and Yocto-based build and test workflows in a polyrepo environment.
- Design and maintain Starlark rules, macros, toolchains, and integrations for hermetic and reproducible builds.
- Improve Buildkite CI performance and reliability, including queue time, build time, cache hit rates, retries, and flaky-test isolation.
- Develop affected-target detection, dependency graph analysis, test selection, caching, batching, and smarter scheduling systems.
- Unify local and CI workflows so engineers can reproduce CI behavior and debug build failures.
- Operate build infrastructure across Docker/OCI images, Kubernetes-based runners, cloud resources, and remote cache and execution systems.
- Instrument build and CI systems with metrics, logs, traces, dashboards, and analytics.
- Partner with users to onboard projects, debug difficult build issues, and remove systemic bottlenecks.
- Apply AI tools to CI failure analysis, flaky-test debugging, pull-request triage, automated remediation, and developer-facing information.
- Own system reliability and participate in an on-call rotation for critical developer and factory infrastructure.
Requirements
- At least 5 years of engineering experience, including significant experience building infrastructure and developer tooling.
- Hands-on experience with Bazel, Buck, Gradle, or similar build systems, including hermetic builds, dependency graphs, caching, sandboxing, and remote execution.
- Experience building CI systems at scale and improving build time, queue time, test flakiness, and developer trust.
- Experience owning production software in environments with strong SLA requirements.
- Ability to debug distributed build and CI failures across source control, dependency management, containers, runners, remote caches, test frameworks, and service infrastructure.
- Experience working in a polyrepo environment with source code from multiple parties.
- Interest in developer experience, reducing operational toil, and applying AI to developer infrastructure.
Benefits
- Hybrid work model requiring four days in the San Francisco office per week
- Relocation assistance for new employees
