A leading quantitative trading firm is seeking experienced C++ engineers to help build the next generation of trading and research infrastructure that powers activity across global financial markets.

This is an opportunity to join a highly collaborative engineering environment where technology sits at the core of the business. You'll work closely with traders, quantitative researchers, and infrastructure specialists to design and optimise systems where performance, reliability, and scalability are critical.

You'll contribute to the design and development of high-performance systems that support real-time trading, market data processing, and quantitative research workflows.

Responsibilities include:

• Developing and optimising low-latency trading infrastructure and distributed systems.
• Building market data, order entry, and execution systems across multiple asset classes.
• Designing resilient, fault-tolerant software capable of operating in demanding production environments.
• Profiling and tuning performance-critical applications for latency and throughput.
• Working on large-scale infrastructure supporting research, simulation, and live trading.
• Collaborating with hardware, networking, and software specialists to unlock performance improvements across the stack.
• Contributing to architectural decisions and driving engineering best practices across the organisation.

• Commercial experience developing production software in modern C++.
• Strong understanding of algorithms, data structures, and software design.
• Experience working on performance-sensitive systems.
• Deep knowledge of Linux/UNIX environments.
• Understanding of operating systems, CPU architecture, memory management, and networking concepts.
• Excellent debugging and problem-solving skills.
• Ability to work independently on complex technical challenges whilst collaborating effectively with other engineers.

• Experience with trading systems, market data, or financial technology.
• Knowledge of low-latency optimisation techniques.
• Experience with distributed systems and high-throughput applications.
• Exposure to specialised hardware or performance-focused infrastructure.

This firm offers a genuinely engineering-led environment where talented developers have significant ownership and can see the impact of their work directly. You'll be surrounded by high-calibre engineers, researchers, and traders, tackling complex technical challenges at scale while working on systems that operate at the limits of performance.

If you're passionate about modern C++, systems engineering, and solving difficult technical problems, this is an opportunity to work on some of the most demanding software challenges in the industry.
