Software Engineer (Developer Infrastructure)

What You Will Do

• Own the design and evolution of the build, test, and release systems that power the platform.
• Define architecture for a Bazel based monorepo, including performance, caching, and dependency graph scalability.
• Improve build performance and correctness, including incremental builds, caching strategies, and graph optimization.
• Design and operate test infrastructure, focusing on reliability, isolation, and signal quality.
• Build and improve release and rollout systems, including deployment pipelines, canarying, and rollback.
• Improve end to end developer velocity, from local iteration to production deployment.
• Debug and resolve complex issues across the pipeline, including build failures, dependency issues, test flakiness, and release regressions.
• Establish standards for reproducibility, observability, and operability across build and release systems.
• Identify and eliminate systemic failure modes across the development lifecycle.
• Contribute broadly across infrastructure and reliability work when needed.
• Mentor engineers and raise the bar for system design and technical decision making.

Key Qualifications

• 5-10 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, with a strong preference for Python.
• 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.
• You have worked on systems where build performance, correctness, and reproducibility were first order concerns, not afterthoughts.

Preferred Qualifications

• Deep experience with Bazel at scale, including remote caching, remote execution, and build graph optimization.
• Experience designing hermetic and reproducible build systems.
• Experience improving test infrastructure at scale, including eliminating flakiness and improving signal quality.
• Experience building or operating release and rollout systems, including canarying, staged rollouts, and rollback mechanisms.
• Experience instrumenting systems for observability and debugging of build, test, and release pipelines.
• Experience in early stage or high growth environments.
