> Build and evolve Bazel, Yocto, and Buildkite-based CI systems for OpenAI consumer device software. Focus on hermetic builds, remote caching, test optimization, observability, and AI-powered failure analysis to accelerate reliable shipping. Requires 5+ years building developer infrastructure at scale.

## Job Description

## 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 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.
- Operate and optimize build infrastructure across Docker/OCI images, Kubernetes-based runners, cloud resources, and remote cache/execution systems.
- 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.
- Use modern AI tools to pioneer novel CI failure analysis, flaky test debugging, PR triage, automated remediation, and developer-facing information.
- Own the reliability of the systems you build, including participating in an on-call rotation for critical developer and factory infrastructure.

## Requirements
- 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 execution.
- Experience building CI systems at scale, especially in environments where build time, queue time, test flakiness, and developer trust materially affect engineering velocity.
- Comfortable with owning production software and working 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.
- Care deeply about developer experience and have empathy for the small sources of friction that slow teams down or create operational toil.
- Excited to apply AI to developer infrastructure in ways that increase team velocity without weakening quality, reliability, or safety.
- Experience operating in a polyrepo environment with source code from multiple parties.

## Technologies
- Bazel and Starlark for build and test workflows
- Buildkite for CI orchestration
- Docker and OCI images for build and runtime packaging
- Kubernetes for CI runners and infrastructure orchestration
- Python, Go, TypeScript, Rust, C++, and other languages in a large monorepo
- Terraform for infrastructure as code
- Remote caching, remote execution, artifact storage, and build telemetry systems
