Senior Rust/C++ Engineer (Backend)

About the Role

You will design, develop, and maintain core backend systems that support a high-throughput order book, index on-chain data into event queues and persistence layers, and expose scalable APIs and WebSockets. You will architect messaging and event-driven patterns, define data storage strategies, and ensure reliability, performance, and high availability. You will implement and harden security measures for backend systems and APIs, develop comprehensive testing strategies (unit, integration, load, security), and produce clear documentation. You will participate in code reviews, mentor other engineers, and evaluate new technologies to improve system scalability and latency.
