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.

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.Your Impact: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 DONsSafe and repeatable infrastructure expansionImproved operational efficiency and scalabilityYou 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.Requirements:6–9+ years in SRE / Platform / Infrastructure EngineeringProven experience scaling Kubernetes in high-throughput production environmentsDeep knowledge of:Scheduler behaviorStatefulSets & persistent workloadsAutoscaling strategies (HPA, VPA, KEDA, custom scaling)Resource management & performance tuningMulti-cluster and multi-region architecturesExperience in diagnosing production failures at the cluster scaleStrong Terraform or Crossplane experienceGitOps...
