> As a Software Engineer, Developer Experience, you will build tools and systems to improve the developer workflow, focusing on CI/CD, build toolchains, and supply chain security. You will work to make shipping to production fast, safe, and reliable for the engineering team.
## Job Description
## 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
* AI Stipend
