Ship quality agents at scale. Braintrust is the AI observability platform for tracing production, running evals, and catching regressions before they reach users. Backed by Greylock, a16z and ICONIQ.
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 Work directly with the engineering team to find friction and remove it — help them be nimble, happy and productive
What they're looking for
- 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

- Supply chain security experience: SBOMs, Sigstore/cosign, SLSA, GitHub Actions hardening
More about this role
Braintrust is the agent observability platform. By actively applying intelligence to agent traces and automatically surfacing the most critical patterns, Braintrust gives teams the visibility to understand how agents behave in production and the tools to improve them.
Teams at Notion, Stripe, Box, OpenAI, and Cloudflare use Braintrust to trace their agents, find the issues in their observability data, and run evals that tell them how to improve.
