The Role

• Core Systems Development: Design, build, and maintain low-latency, high-performance C++ components for real-time market data processing, event handling, and order execution.
• Architecture & Design: Lead system architecture decisions with a focus on memory layout, concurrency models, fault tolerance/error recovery, and high-efficiency inter-process communication (IPC).
• API & Service Integration: Collaborate across cross-functional backend and frontend teams to define robust API contracts and clear system boundaries.
• Performance & Optimisation: Identify latency bottlenecks, conduct deep system profiling, and drive continuous optimization across CPU cache, memory, and networking layers.
• Business Collaboration: Partner closely with traders, quantitative researchers, and product managers to understand, design, and enhance mission-critical trading applications.
• Engineering Excellence: Drive code quality through rigorous code reviews, emphasizing correctness, low overhead, maintainability, and modern C++ best practices.

• 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.
