About the role

Role focused on speeding up and improving the CI, testing, and ephemeral environments in a large TypeScript, React, and Go monorepo, enabling faster, reliable build-test cycles for an agent-heavy platform.

Responsibilities

  • Modernize the JS/TS build: Lead the move to maintain Bazel tooling and replace accumulated workarounds with a cleaner, faster setup.
  • Make CI faster, cheaper, and observable: Track build and test performance, improve caching and parallelism, and give the team the data to make build decisions with confidence.
  • Make testing a first-class developer experience: Own how engineers and agents write, run, and trust tests, with local runs that match CI, automatic flake handling, and quality checks that act as real gates.
  • Build ephemeral, agent-ready environments: Replace shared, long-lived environments with fast, isolated, reproducible ones that people and agents can spin up on demand and use safely in parallel.

Qualifications

  • Build systems depth, including frontend: 6+ years owning a build system, with a deep understanding of build correctness and performance (hermeticity, sandboxing, caching, and invalidation). Hands-on experience owning production frontend build pipelines (webpack, Vite, esbuild, or Turbopack) and shared UI packages.
  • CI/CD as a platform: Experience owning incremental builds, test sharding, runner fleets, presubmit/postsubmit design, and merge queues, with an understanding that services and UI need different feedback loops.
  • TypeScript/Node fluency: Strong expertise in Node.js module resolution and packaging (CJS/ESM, exports).
