Note: The job is a remote job and is open to candidates in USA. Coinbase is a remote-first company focused on increasing economic freedom through cryptocurrency and financial technology. The company is seeking a Senior Software Engineer to join the CB Node team and optimize performance, reliability, observability, and infrastructure costs across blockchain nodes and the broader blockchain platform stack.
Responsibilities
- 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
Skills
- 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)
- Utilizes generative AI responsibly, maintaining human oversight to deliver business-ready outputs and drive measurable improvements in workflow efficiency, cost, and quality
- Experience with blockchain nodes, consensus protocols, or crypto infrastructure is strongly preferred; familiarity with how different protocols behave under load and during upgrades
