Systems Integration Engineer, Build Systems | Consumer Devices

Job summary

Responsibilities

We are looking for an engineer to help evolve OpenAI’s Consumer Products build and continuous integration systems for a fast-growing engineering organization. This role sits at the intersection of developer productivity, build systems, distributed infrastructure, software quality, and on-device…

• Own and evolve Bazel and yocto-based build and test workflows in a polyrepo environment
• Design and maintain Starlark rules, macros, toolchains, and integrations that make builds hermetic, reproducible, and easy for teams to adopt
• Improve CI performance and reliability across Buildkite pipelines, including queue time, build time, cache hit rates, retry behavior, and flake isolation.
• Build systems that reduce unnecessary CI work through affected-target detection, dependency graph analysis, test selection, caching, batching, and smarter scheduling
• Unify local and CI development workflows so engineers can reproduce CI behavior, debug build failures, and iterate quickly without learning every detail of the build stack

What they're looking for

• 5+ years of engineering experience, including significant experience building infrastructure and tooling for developers
• Hands-on experience with Bazel, Buck, Gradle, or similar build systems, and understand the trade offs of hermetic builds, dependency graphs, caching, sandboxing, and remote…
• Have built CI systems at scale, especially in environments where build time, queue time, test flakiness, and developer trust materially affect engineering velocity
