C++/ Python Software Developer/ London / £ High

In this role, your primary focus will be on engineering – crafting robust, low-latency, and high-throughput systems that directly drive trading performance. The role demands an elite level of coding ability, especially in C++ , and a deep interest in how software architecture impacts real-world execution. If you’re passionate about clean code, optimization, and pushing the limits of what software can do in production, this is the environment for you. Key Responsibilities • Design, develop, and deploy high-performance C++ code to power algorithmic trading systems. • Optimize latency-critical components through low-level systems programming, performance tuning, and efficient data handling. • Engage in continuous refactoring, testing, and code review to ensure engineering rigor and production stability. • Work across the stack—from network interaction to execution pipelines—and contribute to system-wide performance gains. • Collaborate with a world-class team of engineers and researchers to translate abstract trading ideas into production-grade code. • Stay current with modern hardware, compiler behavior, and systems-level development techniques. • Build and maintain tooling to support automated testing, monitoring, and deployment in a Linux-based environment. What We're Looking For • Degree in Computer Science, Engineering, Physics, or Mathematics (minimum BSc or equivalent) from a red brick University. • Proven experience as a software engineer—whether through professional roles, open-source contributions, or independent projects. • Expert-level programming in C++ (required), with an emphasis on performance, memory management, and concurrency. • Proficiency in at least one scripting language (preferably Python) for tooling and prototyping. • Strong understanding of system internals—compilers, memory models, CPU architecture, and how code translates into hardware behavior. • Familiarity with Linux systems and modern development practices (e.g., CI/CD, TDD, code reviews). • Interest in algorithm design, data structures, and writing code that is both elegant and efficient. • Clear communicator who can explain technical ideas and collaborate constructively with peers. Why Join • Be part of a deeply technical, tight-knit engineering culture that prioritizes precision, pragmatism, and performance. • Work on greenfield projects that have direct and measurable impact on real-world trading outcomes. • Competitive compensation and the chance to be immersed in a fast-paced environment that rewards technical depth and curiosity.
