Senior Site Reliability Engineer, DevEx

Chainlink Engineering Role

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, stable coins, and more.

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, Wisdom Tree, ANZ, and top protocols such as Aave, Lido, GMX and many others.

As Chainlink Labs' engineering org scales, the Dev Ex 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, Git Ops 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.

• 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:

  • Git Hub Actions self-hosted runner infrastructure (autoscaling, isolation, cost/perf tuning)

  • Git Hub Apps and Git Hub-as-code (permissions, webhooks, org-wide automation)

  • Secure network access for CI/CD and remote dev environments (Tailscale)

  • Git Ops-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/Git Ops ownership — designing and owning automation, not just running playbooks

• Git Ops workflows (Flux / ArgoCD) experience

• Hands-on experience with CI/CD platforms at scale:
  Git Hub Actions (self-hosted runners, workflows-as-code), Git Hub 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

• 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 (Open Telemetry 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 is a plus but not required for this role
