Senior Site Reliability Engineer, DevEx

About the role

The Engineering Team at Chainlink Labs is expanding, and the DevEx team is responsible for the infrastructure primitives that every product team builds, tests, and ships on top of. This role focuses on building the Kubernetes-based control-plane components and automation that power our CI/CD platform, developer environments, and build systems.

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

Preferred Requirements

• Experience with Tailscale or similar zero-trust/overlay networking for CI/CD or remote dev environments
• Experience designing SLO strategies and error-budget usage
• Experience improving diagnosability and observability frameworks (OpenTelemetry or similar)
• Experience building internal developer platforms (IDP) or ephemeral/on-demand dev environments
• Experience building multi-tenant platform infrastructure
• Experience contributing to Kubernetes ecosystem projects
• Experience working in high-ambiguity environments
• Experience with web3 concepts (though not required for this role)
