About The Position

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. As adoption of the Chainlink Runtime Environment (CRE) accelerates, you will be a part of that growth to ensure reliability and security remain at the forefront of development. This role assists in building the Kubernetes-based infrastructure primitives and application control-plane components that CRE runs on, enabling deterministic horizontally scalable deployments with decentralized consensus built in. By codifying scaling logic into reusable operators and automation, you will ensure CRE continues to scale safely, predictably, and efficiently as demand grows. The impact is foundational; the infrastructure you will help build is not constrained by product expansion, operational risk is reduced at scale, and it will help Chainlink strengthen its ability to grow its decentralized network without sacrificing reliability or security.

Requirements

6–9+ years in SRE / Platform / Infrastructure Engineering
Proven experience scaling Kubernetes in high-throughput production environments
Deep knowledge of: Scheduler behavior StatefulSets & persistent workloads Autoscaling strategies (HPA, VPA, KEDA, custom scaling) Resource management & performance tuning Multi-cluster and multi-region architectures
Experience in diagnosing production failures at the cluster scale
Strong Terraform or Crossplane experience
GitOps workflows (ArgoCD / Flux) experience
CI/CD reliability experience
Automation-first mindset
AWS production experience
Proficiency in Go (strongly preferred) or equivalent systems language

Nice To Haves

Experience with web3 concepts (e.g. blockchain node lifecycle, forks, reorgs, or RPC issues)
Experience with oracle systems, token architectures, or decentralized services
Experience scaling stateful high-availability distributed systems
Experience building internal platform primitives
Experience implementing custom autoscaling logic
Experience designing SLO strategies and error-budget usage
Experience improving diagnosability and observability frameworks
Experience working in high-ambiguity environments
Experience operating blockchain infrastructure in production
Certified Kubernetes Administrator (CKA)
Experience contributing to Kubernetes ecosystem projects
Experience building multi-tenant platform infrastructure
Experience working in high-security and/or SOC 2/ISO27001 compliant environments
Experience with chaos engineering practices or implementation

Responsibilities

You will design and build the infrastructure primitives that define how Chainlink Decentralized Oracle Networks (DONs) scale across internal systems and the decentralized ecosystem.
You will help create the CRE (Kubernetes-based) control plane that enables: Deterministic horizontal scaling of DONs Safe and repeatable infrastructure expansion Improved operational efficiency and scalability
You will develop the core infrastructure components, including Kubernetes Operators and scaling automation, that Product teams will adopt and then might later be distributed to external node operators to improve decentralized scaling.
This is not an operational support role. You will be building the systems that define how Chainlink scales while shaping the reliability, scalability, and decentralization of protocol-level services.
