Senior SRE, DevEx Platform & Kubernetes Automation

Chainlink Labs; Las Vegas (NV); On-site; USD 150,000 - 180,000; Full time

Job summary

Chainlink Labs is seeking a senior SRE/Platform/Infrastructure Engineer to scale our Kubernetes-driven CI/CD platform and developer environments. You will build reusable control-plane components, operators, and automation to accelerate product teams while reducing operational toil across the org.

You will own the Kubernetes-based control plane behind CI/CD, including self-hosted runners, GitHub Apps, and Flux-based deployments, with a strong emphasis on reliability and scale.

Qualifications

• 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.
• 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.

Responsibilities

• 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 and 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
• This is not an operational support role; you will shape reliability and scalability of the developer experience org-wide.
