Senior Software Engineer, Blockchain Platform Nodes

We’re hiring a Senior Software Engineer to join the CB Node team within thePlatform organization. This team runs all the blockchain nodes that power every asset Coinbase offers to customers, currently spanning 55 unique protocols across Ethereum, Bitcoin, Solana, and beyond. You’ll focus on performance optimization and reliability across the blockchain platform stack, diagnosing root causes instead of over-provisioning, reducing infrastructure spend, and building the observability and health-check systems that keep our nodes reliable at scale.

What you’ll do:

• 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.
• 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.
• Drive a right-sizing initiative across the node fleet, profiling workloads, identifying over-provisioned instances, and establishing capacity models that balance cost efficiency with headroom for reliability.
• Partner with protocol integration engineers, wallet teams, and indexer teams to extend performance improvements across the full blockchain platform stack, not just the node layer.
• Lead the definition and implementation of SLOs and SLIs for node services, creating the measurement framework that gives the team confidence in reliability without relying on over-provisioning.
• 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.

• 5+ years of experience in software engineering with deep expertise in systems-level performance analysis, profiling, and optimization of production infrastructure.
• 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 (e.g., pprof, Datadog, Prometheus, Grafana).
• Track record of reducing infrastructure costs through engineering optimization rather than simply scaling resources, with measurable outcomes (e.g., cost reduction percentage, latency improvements).
• Experience with blockchain nodes, consensus protocols, or crypto infrastructure is strongly preferred; familiarity with how different protocols behave under load and during upgrades.
• Utilizes generative AI responsibly, maintaining human oversight to deliver business-ready outputs and drive measurable improvements in workflow efficiency, cost, and quality.
