Job description

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.
