Job Description
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.
