Why Apply?
This is an opportunity for an experienced AI engineer to move beyond isolated prototypes and apply AI within a technically demanding, commercially relevant trading environment. You will have meaningful ownership, direct access to sophisticated users, and the freedom to assess new technologies based on measurable value rather than novelty. For someone seeking greater proximity to research and trading, broader technical influence, and a clear route to shaping AI engineering standards across a high-performance business, this offers a compelling next step.
