What you will do

• Own and improve Bazel-based monorepo workflows, including build rules, testing, dependency management, caching, and diagnostics.
• Improve CI performance, reliability, observability, flaky-test handling, and pipeline maintainability.
• Partner with engineering and research teams to reduce friction across local development, builds, tests, releases, and tooling.
• Build internal tools, automation, CLIs, and self-service workflows that reduce repetitive engineering work.
• Diagnose complex build and CI failures across Go, Python, TypeScript, and Java codebases.
• Collaborate on AWS and Kubernetes infrastructure, documentation, standards, and reusable developer-tooling patterns.

Requirements

• 4+ years of experience with build systems, CI/CD, developer productivity, or platform tooling.
• 2+ years of hands-on experience with a large-scale build system such as Bazel, Buck, Pants, Gradle, or CMake.

Nice to have

• Production Bazel experience in a large, multi-language monorepo, including rules, toolchains, remote caching, remote execution, or test sharding.
• Experience with hermetic builds, dependency management, test infrastructure, CI flakiness, and build performance optimization.
• Experience supporting scientific, research, or data-intensive teams and Python packaging or container image workflows.
• Experience building developer platforms, defining productivity metrics, mentoring engineers, or driving tooling adoption.
• Comfort using modern AI coding agents with sound engineering judgment.
