My client, a leading high-frequency trading firm, is seeking a Software Engineer to join their systematic trading team in London. This is an exceptional opportunity to be part of a high-performing systematic trading group that develops and operates mid- to high-frequency, multi-asset trading strategies across global markets.

You’ll work closely with quantitative researchers and traders to design and develop end-to-end, high-availability trading systems using C++ and Python—covering everything from market data connectivity and execution algorithms to research infrastructure, monitoring, and integration with the firm’s global trading platform.

• Designing, developing, and maintaining software for research, trading, and post-trade analysis, including market data handling, signal computation, and execution management.
• Building high-availability distributed systems that support global, around-the-clock trading operations.
• Collaborating closely with quantitative researchers and traders to translate trading ideas into production systems.
• Testing at unit, functional, and integration levels to ensure performance, stability, and resilience.
• Providing on-call support and contributing to continuous improvement of the trading platform.

• 5+ years of professional C++ experience, ideally building low-latency or mission-critical systems.
• Strong understanding of concurrency, networking, and type systems in both C++ and Python.
• Experience developing distributed systems with tight latency constraints.
• Solid grasp of statistics and numerical methods.
• Excellent communication skills and the ability to work autonomously from high-level requirements.
• A passion for learning, innovation, and problem-solving in fast-paced trading environments.

My client anticipates to pay a strong performer upwards of £400k year 1 total compensation package. As well as a market-leading compensation package, they offer exceptional benefits including a top-tier healthcare package, fully subsidised qualifications plus breakfast and lunch paid for each day.
