Note: The job is a remote job and is open to candidates in USA. Chainlink Labs is the industry-standard oracle platform powering decentralized finance. The Senior Site Reliability Engineer will design and build infrastructure primitives for Chainlink's Decentralized Oracle Networks, ensuring reliability and scalability as demand grows.
Responsibilities
- Design and build the infrastructure primitives that define how Chainlink Decentralized Oracle Networks (DONs) scale across internal systems and the decentralized ecosystem
- 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
- 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
- Build the systems that define how Chainlink scales while shaping the reliability, scalability, and decentralization of protocol-level services
