Key responsibilities include:

• Owning the design and evolution of the build, test, and release systems that power the platform.
• Defining architecture for a Bazel-based monorepo, including performance, caching, and dependency graph scalability.
• Improving build performance and correctness, including incremental builds, caching strategies, and graph optimisation.
• Designing and operating test infrastructure, focusing on reliability, isolation, and signal quality.
• Building and improving release and rollout systems, including deployment pipelines, canarying, and rollback.
• Improving end-to-end developer velocity, from local iteration to production deployment.
• Debugging and resolving complex issues across the pipeline, including build failures, dependency issues, test flakiness, and release regressions.
• Establishing standards for reproducibility, observability, and operability across build and release systems.
• Identifying and eliminating systemic failure modes across the development lifecycle.

Requirements include:

• 10 or more years of experience building and operating production systems at scale, with ownership of critical infrastructure.
• Strong experience with build systems and dependency graphs such as Bazel, Buck, Pants, or similar, or the ability to quickly ramp on Bazel in a large monorepo environment.
• Experience designing and improving build, test, and release pipelines, with a focus on performance, correctness, and reproducibility.
• Strong systems understanding of how code moves from source to build to test to production.
• Hands-on experience debugging complex system issues, including build failures, dependency issues, test flakiness, and release regressions.
• Experience owning systems with strict reliability and performance requirements.
• Strong proficiency in at least one of Python, Go, or Rust, and comfort working across languages in a polyglot codebase.
• Proven ability to define architecture and drive technical decisions end-to-end.
• Strong judgment in balancing developer velocity, system complexity, and reliability.
• Ability to operate effectively in ambiguous, fast-moving environments with high ownership.

Preferred qualifications include deep experience with Bazel at scale, including remote caching, remote execution, and build graph optimisation, as well as experience designing hermetic and reproducible build systems.
