Senior Site Reliability Engineer building Kubernetes-based infrastructure for CI/CD at Chainlink Labs. Ensuring engineering velocity scales safely and efficiently across the organization.
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 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.
