What they ask for
- Strong production C++ proficiency, including memory and resource ownership, concurrency, and debugging in substantial codebases.
- Track record independently leading complex systems or distributed-service improvements across multiple components through to reliable production outcomes.
- Strong Linux/UNIX and networking fundamentals, including diagnosing correctness, latency, and resource issues using profiling and operational evidence.
- Experience designing and operating distributed systems and production software, including safe rollout and recovery strategies.
Nice to have
