• In-depth understanding of the fundamentals of low-latency systems: lock-free data structures, mechanical sympathy, cache-line discipline, and the trade-offs between busy-spin and park/wake.

• Experience with Aeron or similar messaging transports (e.g., Chronicle Queue, ZeroMQ, LMAX Disruptor) is highly desirable.

• Familiarity with UDP networking, multicast, and kernel-bypass techniques (e.g., DPDK, RDMA) is a significant advantage.
