About The Position

The Applications team within Risk & Performance Engineering builds the flagship applications our clients rely on every day, such as Trade Blotter, Beacon Quote and Risk Workstation.

As a Senior Software Development Engineer, you will own projects from scoping through to delivery, working across the full stack and with teams across the business. We want a self-starter with high engineering standards and a real commitment to our clients. We use AI agents, including Claude Code, to accelerate development safely, and you will do the same while taking full ownership of the code you deliver.
