OpenAI's Systems Integration team is seeking a Senior Systems Integration Engineer to evolve build and continuous integration systems for consumer device software. This role sits at the intersection of developer productivity, build systems, distributed infrastructure, and software quality.
You will own and evolve Bazel and Yocto-based build and test workflows in a polyrepo environment, designing and maintaining Starlark rules, macros, toolchains, and integrations that make builds hermetic, reproducible, and easy for teams to adopt. You'll improve CI performance and reliability across Buildkite pipelines, including queue time, build time, cache hit rates, retry behavior, and flake isolation.
Key responsibilities include building systems that reduce unnecessary CI work through affected-target detection, dependency graph analysis, test selection, caching, batching, and smarter scheduling. You'll unify local and CI development workflows so engineers can reproduce CI behavior, debug build failures, and iterate quickly. You'll operate and optimize build infrastructure across Docker/OCI images, Kubernetes-based runners, cloud resources, and remote cache/execution systems.
You'll instrument build and CI systems with metrics, logs, traces, dashboards, and analytics to measure speed, reliability, cost, and developer impact. Partner directly with users to understand pain points, onboard projects, debug hard build issues, and remove systemic bottlenecks. You'll use modern AI tools to pioneer novel CI failure analysis, flaky test debugging, PR triage, automated remediation, and developer-facing information.
The role requires 5+ years of engineering experience with significant infrastructure and tooling work. You need hands-on experience with Bazel, Buck, Gradle, or similar build systems, and experience building CI systems at scale. Strong candidates are comfortable owning production software, can debug distributed build and CI failures, care deeply about developer experience, and are excited to apply AI to developer infrastructure. Experience in polyrepo environments is a plus.
This is a hybrid role based in San Francisco with four days in-office per week. OpenAI offers relocation assistance.
