• Own solutions end-to-end, including testing, deployment, and operational support.

• Proven strength in modern C++ (20/23), with a deep understanding of algorithms, concurrency, and systems programming.
• Experience building low-latency or high-throughput systems (financial experience essential).
• Strong problem-solving skills, attention to detail, and a passion for performance optimisation.

Why Apply?

• Cutting-edge tech and a firm-wide commitment to engineering excellence.
• Join a firm that attracts the brightest minds in tech and quantitative finance.
