Skills
About the Role
You will design and build Kubernetes-based infrastructure primitives and automation for CI/CD platforms, build systems, and developer environments. You will develop Kubernetes Operators, scaling automation, GitOps workflows, and secure access capabilities that product teams can adopt directly. You will help build and operate the control plane behind GitHub Actions self-hosted runners, GitHub Apps, Tailscale, Flux, and ephemeral developer environments. Your work will improve the reliability, scalability, and efficiency of how engineers build, test, and deploy software.
