- Design and implement low-latency, high-availability messaging solutions across unicast, multicast, and IPC transport paths
- Tune and profile the full system stack — CPU pinning, NUMA topology, kernel bypass, receive buffer sizing — to squeeze latency out of production infrastructure
- Build and extend Aeron Archive integrations for durable message replay and stream persistence
- Build and design solutions that mitigate risk, implement security, and protect both systems and data
- Write reusable, testable, and efficient code
