Senior Site Reliability Engineer, DevEx

Chainlink Labs seeks a Senior SRE for DevEx team to build and scale Kubernetes-based infrastructure, CI/CD platform, and developer environments. Remote in Canada, salary $90K–$125K.

Chainlink Labs is the industry-standard oracle platform bringing capital markets onchain and powering the majority of decentralized finance (DeFi), adopted by institutions including Swift, Euroclear, Mastercard, Fidelity International and UBS. As Chainlink Labs' engineering org scales, the DevEx team owns the infrastructure primitives that every product team builds, tests, and ships on top of. You will design and build the infrastructure primitives that define how CI/CD platform, build systems, and developer environments scale across the entire engineering org. You will help build and operate the Kubernetes-based control plane behind 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. You will 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. This is not an operational support role: you will be building the systems that define how engineering teams build, test, and deploy, shaping the reliability and scalability of the developer experience org-wide.

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
