Job summary

Coinbase is seeking a Software Engineer to join the CB Node team within the Platform organization. This team runs all the blockchain nodes powering every asset Coinbase offers, spanning 55 protocols across Ethereum, Bitcoin, Solana, and beyond.

You will contribute to performance optimization and reliability across the blockchain platform stack, diagnosing root causes and reducing infrastructure spend. You will own performance analysis, build observability and automated failover, and help

Qualifications

2+ years of experience in software engineering with exposure to systems-level performance analysis or optimization of production infrastructure.
Experience operating distributed systems, diagnosing resource bottlenecks, tuning service performance, or managing capacity.
Proficiency in backend programming (Go preferred) and familiarity with profiling, tracing, and observability tools (pprof, Datadog, Prometheus, Grafana).
Demonstrated ability to improve infrastructure efficiency through engineering optimization rather than simply scaling resources.
Exposure to blockchain nodes, consensus protocols, or crypto infrastructure is a plus; curiosity about 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.

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.
