Coinbase is hiring a Senior Software Engineer to join the CB Node team within the Platform organization. This team operates all blockchain nodes powering Coinbase's customer offerings across 55+ protocols including Ethereum, Bitcoin, Solana, and others.
You will own deep performance analysis and optimization across the blockchain node stack, diagnosing root causes of resource consumption and implementing system-level fixes that reduce infrastructure spend while maintaining reliability SLOs. You'll build observability, health-check, and automated failover capabilities for blockchain nodes, enabling the team to detect degradation and respond proactively rather than reactively scaling resources.
Key responsibilities include driving a right-sizing initiative across the node fleet by profiling workloads, identifying over-provisioned instances, and establishing capacity models that balance cost efficiency with reliability headroom. You'll partner with protocol integration engineers, wallet teams, and indexer teams to extend performance improvements across the full blockchain platform stack. You'll lead the definition and implementation of SLOs and SLIs for node services, creating measurement frameworks that give the team confidence in reliability without over-provisioning. You'll also support protocol upgrades and node operations with a performance-first lens, ensuring new blockchain versions are validated for resource efficiency and regression-tested before production rollout.
Required qualifications include 5+ years of software engineering experience with deep expertise in systems-level performance analysis, profiling, and optimization of production infrastructure. You need hands-on experience operating distributed systems at scale, including diagnosing resource bottlenecks, tuning service performance, and managing capacity across heterogeneous workloads. Proficiency in backend programming (Go preferred) and systems tooling for profiling, tracing, and observability (pprof, Datadog, Prometheus, Grafana) is essential. You should have a track record of reducing infrastructure costs through engineering optimization rather than simply scaling resources, with measurable outcomes. Experience with blockchain nodes, consensus protocols, or crypto infrastructure is strongly preferred.
