📋 Description

• design and build the infrastructure primitives that define how our CI/CD platform, build systems, and developer environments scale across the entire engineering org. • help build and operate the Kubernetes-based control plane behind our CI/CD platform, including: • - GitHub Actions self-hosted runner infrastructure (autoscaling, isolation, cost/perf tuning) • - GitHub Apps and GitHub-as-code (permissions, webhooks, org-wide automation) • - Secure network access for CI/CD and remote dev environments (Tailscale) • - GitOps-driven deployment of platform services (Flux) • - Ephemeral/on-demand developer environments and build systems • develop the core infrastructure components — including Kubernetes Operators and scaling automation — that product teams adopt directly, reducing bespoke per-team CI/CD and environment tooling. • building the systems that define how engineering teams build, test, and deploy, shaping the reliability and scalability of the developer experience org-wide.

🎯 Requirements

• 6–9+ years in SRE / Platform / Infrastructure Engineering • Proven experience scaling Kubernetes in high-throughput production environments • Deep Kubernetes expertise beyond operating clusters — internals, scheduler behavior, custom resources, and cluster-scale failure diagnosis • Experience building platform infrastructure, control planes, or Kubernetes Operators (not just consuming them) • Strong distributed systems and production reliability experience • Terraform/GitOps ownership — designing and owning automation, not just running playbooks • GitOps workflows (Flux / ArgoCD) experience • Hands-on experience with CI/CD platforms at scale: GitHub Actions (self-hosted runners, workflows-as-code), GitHub Apps, and build systems • AWS/cloud infrastructure production experience • Proficiency in Go (strongly preferred) or another systems language • Track record of building infrastructure primitives rather than primarily performing support/operations — automation-first mindset.
