About the Role

We're looking for an Engineer who loves building tools for other engineers. You'll own the systems we touch every day - local dev, CI, and the deploy pipeline - and make shipping to production fast, safe, and reliable. The work compounds across every engineer at the company and is very important to our whole team

What You'll Do

  • 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 our build toolchain - bundlers, compilers, monorepo tooling - and keep cold builds and rebuilds fast as the codebase and archictecture 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

Ideal Candidate Credentials

  • 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

Benefits Include

  • Medical, dental, and vision insurance
  • Daily lunch, snacks, and beverages
  • Flexible time off
  • Competitive salary and equity
  • Wifi & cellphone stipend
