Performance Engineering Lead

The Performance Engineering Lead at Protocol will drive the scalability and robustness of Ethereum in real-world production scenarios. Your primary mission will be ensuring Ethereum can meet the demands of global usage at scale. You will collaborate closely with our internal DevOps team, EthPandaOps, Ethereum client teams, and applied researchers to identify and resolve bottlenecks, improve node and network performance, and enhance Ethereum’s overall efficiency in live, production environments. You’ll be responsible for establishing a comprehensive approach to performance monitoring, profiling, and optimization specifically tailored for large-scale production deployments of Ethereum nodes, such as RPC services; working closely with EthPandaOps and external ecosystem stakeholders to identify, analyze, and resolve performance issues at scale; developing and refining tools, benchmarks, and best practices to ensure optimal performance of Ethereum across diverse, real world distributed deployments. This role is ideal for a senior engineer who thrives in environments combining complex distributed systems, large-scale monitoring, and data-driven performance optimization.
