Low-Latency & High-Throughput: Proven track record architecting and deploying low-latency, high-throughput, and fault-tolerant distributed trading systems.
Systems & Hardware Awareness: Deep understanding of threading models, lock-free/wait-free data structures, memory layout, cache coherence, and CPU architecture optimisations.
Profiling & Debugging: Advanced proficiency with Linux profiling and debugging toolchains (e.g., perf, gdb, valgrind, Address/Thread Sanitizers).
Networking Protocols: Solid working knowledge of networking stack optimization and protocols (e.g., TCP, UDP, Kernel Bypass, WebSockets).
Messaging & Architecture: Practical experience with event-driven architectures, asynchronous processing, and messaging queues/brokers (e.g., ZeroMQ, Kafka, or custom IPC protocols).
Technical Leadership: Experience leading architectural design sessions, writing comprehensive technical spec documents, and mentoring engineering teams.
Communication: Strong interpersonal and communication skills with the ability to bridge technical requirements across trading desks, backend, and frontend teams.
