About the role
We are seeking a highly skilled Low-Latency Software Engineer to join our technology team responsible for building and maintaining the core infrastructure of our equities trading platform. You will focus on developing and optimizing ultra-low-latency systems that facilitate high-speed, high-volume equity trading, ensuring the exchange remains fast, reliable, and resilient.
What you will do in the role • Design, develop, and maintain low-latency trading systems that ensure efficient and secure execution of equity trades. • Work on matching engines, order routing, and market data distribution systems to optimize trade execution performance. • Build systems to process millions of transactions per second with minimal latency and maximum throughput. • Implement real-time processing pipelines for financial data, ensuring high accuracy and consistency in time-sensitive environments. • Conduct latency analysis, performance benchmarking, and system optimization using advanced profiling techniques. • Collaborate with exchange operations teams, traders, and other developers to meet the rigorous performance demands of equity markets. • Manage and optimize network protocols for market data distribution, including the handling of TCP/IP and UDP connections for rapid data dissemination. • Develop robust systems to handle bursty, high-throughput market conditions, ensuring fault tolerance, high availability, and minimal downtime. • Implement low-latency algorithms and strategies for trade execution while ensuring compliance with exchange regulations.
Required Skills • Expert proficiency in low-latency programming, especially with modern C++, Java and Kotlin • In-depth knowledge of multi-threading, concurrency, and parallel programming to develop efficient real-time systems. • Extensive experience with high-frequency, low-latency software systems, ideally in financial markets, exchanges, or trading environments. • Strong understanding of network programming and socket communication (e.g., TCP/IP, UDP) for market data distribution and order execution. • Familiarity with matching engines, order books, and equity trading protocols (e.g., FIX, OUCH, ITCH). • Experience optimizing software for low-latency I/O, memory management, and CPU cache utilization. • Knowledge of kernel bypass techniques such as DPDK, RDMA, or TCPDirect for minimizing network latency. • Experience with Linux tuning and real-time operating systems to enhance system performance. • Proficiency in latency measurement and profiling tools (e.g., perf, gdb, Valgrind) for analyzing and optimizing system performance. • Familiarity with distributed systems, message buses, and event-driven architectures for building scalable, fault-tolerant applications. • Understanding of financial markets, equity instruments, and market microstructure.
Preferred Qualifications • Knowledge of high-frequency trading environments or other asset classes beyond equities. • Familiarity with low-latency storage solutions for market data. • Knowledge of Reg NMS and other regulatory requirements related to equity trading • Strong analytical and problem-solving abilities, particularly under high-pressure situations. • Attention to detail with a strong focus on precision and performance. • Ability to communicate complex technical concepts to both technical and non-technical stakeholders. • Team player with a collaborative mindset, but able to work independently on complex tasks. • Adaptable to the fast-moving, dynamic nature of financial markets and technological innovation.
