You'll build the systems that take code from idea to production, including the infrastructure that lets agents build, deploy, test, and verify autonomously. This is a hands-on role for someone who has built developer and delivery infrastructure at an AI or high-growth startup and wants to define how autonomous agents move code to production. What You'll Do * Build an agent development experience that streamlines idea to production, letting agents build, deploy, test, and verify code autonomously * Build a self-hosted software builder, a secure GitHub Actions Runner alternative that meets our compliance requirements * Adopt and operate a solution to provision infrastructure securely
