You will also play a central role in setting engineering standards and best practices, ensuring that theoretical soundness and practical performance work hand in hand in production systems.More specifically, your responsibilities include:

designing and implementing core components of automated trading systems in Rust, with a focus on low‑latency execution, deterministic behaviour, and resilience in continuously running production environments

translating theoretical concepts and quantitative requirements into performant, testable, and maintainable software across the full system lifecycle

active participation in architectural discussions and technical decision‑making, balancing trade-offs between complexity, performance, correctness, and long‑term evolvability

driving performance engineering initiatives, including profiling, benchmarking, concurrency design, memory optimisation, and analysis of behaviour under load

mentoring engineers and acting as a technical reference point, raising the overall engineering maturity of the organisation through reviews, guidance, and example

We work with automated execution platforms, exchange connectivity and real-time trading infrastructure, enabling algorithmic trading across multiple markets. Our systems run live in the market, where performance issues or failures have immediate consequences, and it is our responsibility to mitigate this risk.You will join the Automated & Quantitative Trading Technology team, where we ensure that the automated trading capabilities are built on sound engineering principles and world-class technical foundations.

Our systems run live in the market, where performance issues or failures have immediate consequences, and it is our responsibility to mitigate this risk.We are a team of highly experienced engineers with technical curiosity and professional discipline, working on complex, high‑impact systems. We have backgrounds in computer science, mathematics, systems engineering, and trading technology, united by a shared respect for correctness and rigor. We are a focused, collaborative, and technically demanding team, where design quality and empirical validation matter, and we continuously refine our solutions by deepening our understanding of both the systems we build and the markets they operate in.We are a team of highly experienced engineers with technical curiosity and professional discipline, working on complex, high‑impact systems.

We also picture you as someone who takes a measured, ownership-driven approach, where long-term system health and collective outcomes are prioritised over short-term optimisations.As you will be working in a hybrid setup with close collaboration across engineering, quantitative teams and trading, it is important that you can reason rigorously about complex systems, communicate technical trade-offs clearly, and influence decisions through sound technical arguments.
