Software Engineer (On Desk) - Trading Developer - Systematic Strategies London (Hybrid) High Compensation

We are partnered with a leading global trading firm that has been operating for decades at the intersection of markets, technology, and innovation. With offices across North America, Europe, and Asia, they bring together world-class engineers and researchers to solve some of the most complex challenges in systematic trading.

Their London-based systematic team is expanding and seeking a Trading Developer to play a pivotal role in building and enhancing their core trading platform. This is a high-impact role within a small, elite group where your contributions will be felt immediately across the business.

The Role

• Join a tight-knit team of trading technologists (currently 2 in London, with further growth planned in the US), working directly alongside researchers and trading leads.
• Take full ownership of the firm's primary systematic trading platform, ensuring stability and scalability across all components - market data, execution, and trading algorithms.
• Play a central role in the ongoing transition to modern C++, while still contributing to Python systems and integrations.
• Tackle the full lifecycle: design, development, testing, deployment, and support - building mission-critical systems that trade globally, 24/7.
• Work in an environment where deep domain knowledge and technical excellence are equally valued.

What They're Looking For

• Proven experience building complex, high-performance systems in C++ (deep, practical knowledge - not just theoretical).
• Exposure to systematic trading environments (front-to-back awareness: data ingestion, strategy implementation, execution, and risk).
• Strong problem-solving ability, with the autonomy to drive projects end-to-end.
• Willingness to work closely with researchers, contributing to strategy development and operational excellence.
• Python skills are beneficial, especially for bridging systems and rapid prototyping.
