• Strong production C++ proficiency, including memory and resource ownership, concurrency, and debugging in substantial codebases. • A track record of independently leading complex systems or distributed-service improvements across multiple components, from an unclear problem to a reliable production outcome. • Strong Linux/UNIX and networking fundamentals, with experience diagnosing correctness, latency, and resource-consumption issues using profiling and operational evidence. • Experience designing and operating distributed systems, with sound judgment about service boundaries, data partitioning, consistency, timeouts and retries, backpressure, capacity limits, and recovery from partial failures. • Experience designing safe rollout and recovery strategies and maintaining production software over its lifecycle. • Ability to communicate trade-offs clearly, align stakeholders, mentor teammates, and improve engineering practices through constructive feedback. • A willingness to work across C++, Rust, Go, and TypeScript and learn unfamiliar parts of the stack.
