Systems Integration Engineer, Build Systems | Consumer Devices

About the TeamThe Systems Integration team is responsible for building the infrastructure, tooling, and validation systems that ensure our device software our device software is reliable, testable, and ready to ship. We design and maintain build systems, CI pipelines, automated test frameworks, and hardware-in-the-loop labs to enable rapid, safe product launches. Our work spans build systems, developer tools, systems integration, and cross-team collaboration to ensure developers can build reliably and ship with confidence.About the RoleWe 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 software. You will work on the systems that determine how quickly and confident engineers can move: Bazel-bazed builds, Buildkite pipelines, test coverage, remote caching and execution, CI observability, and tooling that helps engineers understand and fix failures quickly.Our mission is to enable OpenAI to ship software running on consumer devices rapidly with a high bar for correctness, reliability, and safety. The best version of this work is invisible when it succeeds: builds are fast, tests are trusted, CI failures are understandable, and engineers can focus on shipping products instead of fighting infrastructure.This role is based in San Francisco, CA. We use a hybrid work model of four days in the office per week and offer relocation assistance to new employees.In This Role, You WillOwn and evolve Bazel and yocto-based build and test workflows in a polyrepo environmentDesign and maintain Starlark rules, macros, toolchains, and integrations that make builds hermetic, reproducible, and easy for teams to adoptImprove 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 schedulingUnify local and CI development workflows so engineers can reproduce CI behavior, debug build failures, and iterate quickly without learning every detail of the build stackOperate and optimize build infrastructure across Docker/OCI images, Kubernetes-based runners, cloud resources, and remote cache/execution systemsInstrument build and CI systems with metrics, logs, traces, dashboards, and analytics so we can measure speed, reliability, cost, and developer impactPartner directly with users to understand pain points, onboard projects, debug hard build issues, and remove systemic bottlenecksUse modern AI tools to pioneer novel CI failure analysis, flaky test debugging, PR triage, automated remediation, and developer-facing informationOwn the reliability of the systems you build, including participating in an on-call rotation for critical developer and factory infrastructureTechnologies Commonly Used In This Environment IncludeBazel and Starlark for build and test workflowsBuildkite for CI orchestrationDocker and OCI images for build and runtime packagingKubernetes for CI runners and infrastructure orchestrationPython, Go, TypeScript, Rust, C++, and other languages in a large monorepoTerraform for infrastructure as codeRemote caching, remote execution, artifact storage, and build telemetry systemsYou May Be A Strong Fit If YouHave 5+ years of engineering experience, including significant experience building infrastructure and tooling for developersHave 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 executionHave built CI systems at scale, especially in environments where build time, queue time, test flakiness, and developer trust materially affect engineering velocityAre comfortable with owning production software and working in environments with strong SLA requirementsCan debug distributed build and CI failures across source control, dependency management, containers, runners, remote caches, test frameworks, and service infrastructure.Care deeply about developer experience and have empty for the small sources of friction that slow teams down or create operational toilAre excited to apply AI to developer infrastructure in ways that increase team velocity without weakening quality, reliability, or safetyHave operated in a polyrepo environment with source code from multiple partiesAbout OpenAIOpenAI is an AI research and deployment company dedicated to ensuring that general-purpose artificial intelligence benefits all of humanity. We push the boundaries of the capabilities of AI systems and seek to safely deploy them to the world through our products. AI is an extremely powerful tool that must be created with safety and human needs at its core, and to achieve our mission, we must encompass and value the many different perspectives, voices, and experiences that form the full spectrum of humanity.
