• Building and enhancing exchange and broker connectivity, including order routing and market data pipelines

• Collaborating closely with traders, quantitative researchers, and technologists to deliver new functionality and improve existing platforms

• Contributing to core libraries and shared infrastructure, promoting clean, reusable, and maintainable code

• Supporting production systems and participating in controlled releases in a fast-moving trading environment

Key Requirements

• Strong hands-on experience in C++ (C++17/20+)

• Solid knowledge of data structures, algorithms, and system design

• Experience with multi-threaded, parallel, and asynchronous programming

• Strong understanding of performance optimisation and low-latency systems

• Experience working in Linux/Unix environments

• Exposure to trading systems, market data, execution platforms, or exchange connectivity

• Ability to communicate effectively with both technical and non-technical stakeholders

Nice to Have
