Senior Site Reliability Engineer, DevEx

Chainlink Labs; United States; Remote; USD 150,000 - 210,000; Full time

Job summary

Chainlink Labs is seeking an experienced SRE/Platform Engineer to design and scale infrastructure that underpins our CI/CD platform, build systems, and developer environments.

You will help operate the Kubernetes-based control plane and build Operators and automation that product teams rely on, reducing bespoke tooling across the org. The role emphasizes automation-first mindset and reliability at scale.

Qualifications

• 6–9+ years in SRE / Platform / Infrastructure Engineering.
• Proven experience scaling Kubernetes in high-throughput production environments.
• Deep Kubernetes internals knowledge beyond operating clusters — scheduler, CRDs, and cluster-scale failure diagnosis.
• Experience building platform infrastructure, control planes, or Kubernetes Operators.
• 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.

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.
• Develop core infrastructure components — including Kubernetes Operators and scaling automation — adopted by product teams.
• Build systems that shape reliability and scalability of the developer experience org-wide; not just operational support.

Job description

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 chain.link.

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:

• 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

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 ephemera/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

All roles with Chainlink Labs are global and remote-based. Unless otherwise stated, we ask that you try to overlap some working hours with Eastern Standard Time (EST).
