What We’re Looking For

• Excellent core Java skills
• Extensive experience of Java Application and Garbage Collection optimization
• Exceptional knowledge of concurrency and multithreaded programming
• Experience of developing low latency pricing and trading systems
• Knowledge of low latency messaging (e.g. Aeron, 29West)
• Solid understanding of networking fundamentals (TCP/UDP, multicast, routing, switching, congestion control) and use of kernel bypass technologies (e.g., DPDK, Solarflare/OpenOnload, RDMA).
• Familiarity with Linux internals, to include scheduling, memory management, and performance tuning.

Bonus Points

• eFX development experience in a low latency, zero GC environment
• Knowledge of institutional encodings (FIX, SBE)
• Fault tolerant, high availability, distributed computing
• Docker / Kubernetes / AWS
