Full Job Description
About the Role

We're hiring a Developer Experience Engineer on our Core Platform team to own the software delivery lifecycle - the build, CI/CD, and provisioning systems that let both engineers and agents ship securely and fast. 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
What We're Looking For
  • Deep experience with CI/CD and build systems: GitHub Actions, Harness, Spacelift
  • Strong infrastructure-as-code skills with Terraform
  • Comfort working in an agent-forward environment with Claude Code and Codex
  • 2-4 years at an AI startup, plus 2-4 years at a successful high-growth tech company
Bonus Points
  • Self-hosting experience across GitHub and ECR
  • Build tooling experience: Pants, uv, e2b, pico
  • Artifactory
  • Prior startup founder experience
  • A secondary spike in Application Security
For California Based Applicants

The standard base salary range for this position is $100,000 - $300,000 annually. Compensation offered will be determined by factors such as location, job level, job-related knowledge, skills, and experience. Certain roles may be eligible for variable compensation, equity, and benefits.
