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

1. Design, develop, and deploy high-performance C++ code to power algorithmic trading systems.
2. Optimize latency-critical components through low-level systems programming, performance tuning, and efficient data handling.
3. Engage in continuous refactoring, testing, and code review to ensure engineering rigor and production stability.
4. Work across the stack—from network interaction to execution pipelines—and contribute to system-wide performance gains.
5. Collaborate with a world-class team of engineers and researchers to translate abstract trading ideas into production-grade code.
6. Stay current with modern hardware, compiler behavior, and systems-level development techniques.
7. Build and maintain tooling to support automated testing, monitoring, and deployment in a Linux-based environment.

What We're Looking For

1. Degree in Computer Science, Engineering, Physics, or Mathematics (minimum BSc or equivalent) from a red brick University.
2. Proven experience as a software engineer—whether through professional roles, open-source contributions, or independent projects.
3. Expert-level programming in C++ (required), with an emphasis on performance, memory management, and concurrency.
4. Proficiency in at least one scripting language (preferably Python) for tooling and prototyping.
5. Strong understanding of system internals—compilers, memory models, CPU architecture, and how code translates into hardware behavior.
6. Familiarity with Linux systems and modern development practices (e.g., CI/CD, TDD, code reviews).
7. Interest in algorithm design, data structures, and writing code that is both elegant and efficient.
8. Clear communicator who can explain technical ideas and collaborate constructively with peers.

Why Join

1. Be part of a deeply technical, tight-knit engineering culture that prioritizes precision, pragmatism, and performance.
2. Work on greenfield projects that have direct and measurable impact on real-world trading outcomes.
3. Competitive compensation and the chance to be immersed in a fast-paced environment that rewards technical depth and curiosity.
