Senior Site Reliability Engineer, Node Platform

Role Overview

• 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.
