[Remote] Senior Site Reliability Engineer, Node Platform

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 (DeFi) and is seeking a Senior Site Reliability Engineer for their Node Platform. The role involves designing and building infrastructure primitives to ensure reliability and scalability of Chainlink's decentralized oracle networks, focusing on Kubernetes-based control plane components.ResponsibilitiesYou will design and build the infrastructure primitives that define how Chainlink Decentralized Oracle Networks (DONs) scale across internal systems and the decentralized ecosystemYou 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 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 scalingThis 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 servicesSkills6–9+ years in SRE / Platform / Infrastructure EngineeringProven experience scaling Kubernetes in high-throughput production environmentsDeep knowledge of: Scheduler behavior, StatefulSets & persistent workloads, Autoscaling strategies (HPA, VPA, KEDA, custom scaling), Resource management & performance tuning, Multi-cluster and multi-region architecturesExperience in diagnosing production failures at the cluster scaleStrong Terraform or Crossplane experienceGitOps workflows (ArgoCD / Flux) experienceCI/CD reliability experienceAutomation-first mindsetAWS production experienceProficiency in Go (strongly preferred) or equivalent systems languageExperience with web3 concepts (e.g. blockchain node lifecycle, forks, reorgs, or RPC issues)Experience with oracle systems, token architectures, or decentralized servicesExperience scaling stateful high-availability distributed systemsExperience building internal platform primitivesExperience implementing custom autoscaling logicExperience designing SLO strategies and error-budget usageExperience improving diagnosability and observability frameworksExperience working in high-ambiguity environmentsExperience operating blockchain infrastructure in productionCertified Kubernetes Administrator (CKA)Experience contributing to Kubernetes ecosystem projectsExperience building multi-tenant platform infrastructureExperience working in high-security and/or SOC 2/ISO27001 compliant environmentsExperience with chaos engineering practices or implementationCompany OverviewChainlink Labs provides open-source blockchain oracle solutions and specializes in the development and integration of chainlink.
