This is a high-impact, hands-on development role focused on building and optimizing low-latency trading algorithms and infrastructure. The position is based in London and requires significant on-site presence, reflecting the collaborative, fast-paced nature of the business.

Team Overview

The team sits within the Equities division, specifically supporting electronic and algorithmic trading across EMEA markets. They focus on designing proprietary execution algorithms, building model-based trading logic, and developing analytics tools that power decision-making and performance optimization.

This team plays a central role in ensuring the firm remains competitive in modern electronic markets by integrating quantitative techniques and high-performance engineering.

This role is ideal for someone who straddles the line between quant and developer—comfortable writing production-level Java code while also contributing to strategy and model development. If you have experience in front-office trading teams and enjoy working with data to drive trading decisions, this is a rare opportunity to join a technically advanced and intellectually rigorous environment.
