About the role
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 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
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
Equal Opportunity

Before you apply
Applying takes about a minute. These four things decide how fast it moves after that.
Your profile is current
It's what we read first. Occupations, seniority and locations matter more than a long history.
Two examples you can talk through
Not a portfolio — just two pieces of work where you can explain the decisions and what you'd change.
A number in mind
What you're on now and what would make you move. We negotiate better when we know both.
Your notice period
Employers plan around it, and it's the question that stalls offers most often.
Once you apply, someone reads it and calls you before anything reaches the employer — usually within two working days.
