About the role

Engineer focused on building tools for other engineers, owning local dev, CI, and deploy pipeline to enable fast, safe, reliable production shipping.

Responsibilities

  • Work directly with the engineering team to find friction and remove it — help them be nimble, happy and productive
  • Drive CI runtime down: parallelization, caching, sharding, test selection, and killing flakes
  • Own the deploy pipeline: progressive rollouts, fast rollbacks, and clear signals when something is wrong
  • Own the build toolchain — bundlers, compilers, monorepo tooling — and keep cold builds and rebuilds fast as the codebase and architecture grows
  • Harden our supply chain: SBOMs, signed artifacts, locked-down GitHub Actions, secret hygiene, and provenance for every build
  • Build CLIs, GitHub Apps, and bots that make the right thing the easy thing

Qualifications

  • 5+ years building developer tools, CI/CD, or platform infrastructure
  • A track record of taking slow, painful workflows and making them fast and pleasant
  • Deep GitHub expertise: Actions, Apps, APIs, merge queues, and branch protections
  • Strong fluency with JavaScript/TypeScript build and bundling tools (esbuild, swc, Vite, Turbopack, tsc, pnpm) and a clear sense of when to reach for which
  • Comfortable profiling and optimizing across the stack — flamegraphs, tracing, and just plain measurement
  • Supply chain security experience: SBOMs, Sigstore/cosign, SLSA, GitHub Actions hardening
  • Strong opinions on safe, reliable production deploys
