Senior Site Reliability Engineer, DevEx

About Chainlink
Chainlink is the industry-standard oracle platform bringing the capital markets onchain and powering the majority of decentralized finance (DeFi). The Chainlink stack provides the essential data, interoperability, compliance, and privacy standards needed to power advanced blockchain use cases for institutional tokenized assets, lending, payments, stablecoins, and more. Since inventing decentralized oracle networks, Chainlink has enabled tens of trillions in transaction value and now secures the vast majority of DeFi.

Many of the world’s largest financial services institutions have also adopted Chainlink’s standards and infrastructure, including Swift, Euroclear, Mastercard, Fidelity International, UBS, S&P Dow Jones Indices, FTSE Russell, WisdomTree, ANZ, and top protocols such as Aave, Lido, GMX and many others. Chainlink leverages a novel fee model where offchain and onchain revenue from enterprise adoption is converted to LINK tokens and stored in a strategic Chainlink Reserve. Learn more at .
About The Role
The Engineering Team

As Chainlink Labs ’ engineering org scales, the DevEx team owns the infrastructure primitives that every product team builds, tests, and ships on top of. This role builds the Kubernetes-based control-plane components and automation that power our CI/CD platform, developer environments, and build systems — not the manual operation of them. By codifying platform logic into reusable Kubernetes Operators, GitOps workflows, and automation, you will ensure engineering velocity scales safely, predictably, and efficiently as the org grows. The impact is foundational: the infrastructure you build is not constrained by any single product’s roadmap, operational toil is reduced org-wide, and it directly determines how fast every other engineering team at Chainlink Labs can ship.
Your Impact

-
You will design and build the infrastructure primitives that define how our 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 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

-
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.

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
