Software Engineer, Blockchain Platform Nodes

Responsibilities

• Own performance analysis and optimization tasks across the blockchain node stack, diagnosing root causes of resource consumption and implementing system-level fixes that reduce infrastructure spend while maintaining reliability SLOs.
• Build observability, health-check, and automated failover capabilities for blockchain nodes, ensuring the team can detect degradation and respond proactively rather than reactively scaling resources.
• Execute right-sizing improvements across the node fleet, profiling workloads, identifying over-provisioned instances, and contributing to capacity models that balance cost efficiency with reliability.
• Partner with protocol integration engineers, wallet teams, and indexer teams to extend performance improvements across the blockchain platform stack.
• Support the definition and implementation of SLOs and SLIs for node services, helping create measurement frameworks that give the team confidence in reliability without relying on over-provisioning.
• Support protocol upgrades and node operations with a performance-first lens, validating new blockchain versions for resource efficiency and regression-testing before production rollout.
