Systems Integration Engineer, Build Systems | Consumer Devices
Build and operate scalable build systems, CI pipelines, and developer infrastructure for consumer-device software. The role requires 5+ years of engineering experience, expertise with Bazel or comparable build systems, and experience improving CI reliability and performance at scale.
About the job
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, reproducible builds.
- Improve Buildkite CI performance and reliability, including queue time, build time, cache hit rates, retries, and flaky-test isolation.
- Reduce unnecessary CI work through affected-target detection, dependency-graph analysis, test selection, caching, batching, and smarter scheduling.
- Unify local and CI workflows to improve build-failure reproduction and debugging.
- Operate build infrastructure across Docker/OCI images, Kubernetes runners, cloud resources, and remote caching/execution systems.
- Instrument build and CI systems with metrics, logs, traces, dashboards, and analytics.
- Partner with engineering users to diagnose build issues, onboard projects, and remove systemic bottlenecks.
- Apply AI to CI failure analysis, flaky-test debugging, pull-request triage, automated remediation, and developer-facing tooling.
- Participate in an on-call rotation for critical developer and factory infrastructure.
Requirements
- 5+ years of engineering experience, including significant experience building developer infrastructure and tooling.
- Hands-on experience with Bazel, Buck, Gradle, or similar build systems.
- Understanding of hermetic builds, dependency graphs, caching, sandboxing, and remote execution.
- Experience building CI systems at scale, particularly where build time, queue time, test flakiness, and developer trust affect engineering velocity.
- Ability to own 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 operating in a polyrepo environment with source code from multiple parties.
Preferred Qualifications
- Strong focus on developer experience and reducing operational toil.
- Interest in applying AI to developer infrastructure while maintaining quality, reliability, and safety.
