• Optimize node performance, storage, networking, and containerization using Docker/Kubernetes
• Monitor and troubleshoot blockchain health metrics (block height, peer count, sync status, logs, memory, throughput)

Blockchain Application & Service Support

• Support on-chain/off-chain interactions, transactions, gas fees, signing, wallets, smart contract invocations, and state queries
• Troubleshoot blockchain errors (transaction failures, RPC timeouts, indexing lag, sync divergence)
• Work with API gateways and middleware services (Infura, Alchemy, Quick Node equivalents)

Blockchain Data & Indexing

• Implement indexing for event logs, state, and transactions using tools like The Graph, ETL pipelines, custom services, or database-backed explorers

Site Reliability Engineering, Automation & Dev Ops

• Implement Terraform, Helm, and Git Ops workflows for infrastructure lifecycle management
• Enforce resilient, automated, scalable design patterns and collaborate on faster, higher-quality deployments
• Own availability, latency, performance, capacity, SLOs/SLIs/SLAs with observability-driven insights
• Lead on-call rotations, incident response for S1/S2 events, post-incident reviews, and preventive initiatives
• Reduce operational toil through automation; own and build CI/CD pipelines (Jenkins, Git Hub Actions), Terraform validation, Docker builds, Helm deployments
