Depending on team alignment and experience, responsibilities may include:

• Designing and developing ultra-low-latency order entry systems.
• Building and optimising options trading platforms.
• Developing market data infrastructure and exchange connectivity.
• Improving execution performance through deep systems-level optimisation.
• Creating scalable distributed systems that process vast amounts of real-time data.
• Working closely with traders, quantitative researchers, and fellow engineers to solve complex technical challenges.
• Driving architectural decisions and contributing to the technical direction of critical trading platforms.

What We're Looking For

• Strong commercial experience with modern C++.
• Expertise in performance optimisation, multithreading, concurrency, and Linux.
• Strong understanding of systems programming fundamentals.
• Experience building highly performant, business-critical software.
• Excellent problem-solving skills and a passion for engineering excellence.
• Ability to thrive in a collaborative, fast-paced environment.

Beneficial Experience

• Low-latency trading systems.
• Exchange connectivity and market data.
• Options or derivatives trading technology.
• Network optimisation and kernel bypass technologies.
• High-performance distributed systems.
• Financial markets, trading, or quantitative environments.

Why Join?

• Work alongside world-class engineers, quantitative researchers, and traders.
• Significant ownership and direct impact on revenue-generating systems.
• A highly technical engineering culture where performance and innovation are valued.
• Opportunities across multiple trading desks and business areas.
• Access to challenging technical problems at exceptional scale.
• Competitive compensation, bonus potential, and long-term career growth.

This is an excellent opportunity for senior C++ engineers who enjoy solving complex performance challenges and want to build technology that sits directly at the heart of global financial markets.
