Senior Software Engineer - Fixed Income Trading in London

The company’s Fixed Income Trading systems offer end-to-end trading workflows including price discovery and negotiation, real-time analytics/pricing and execution, and are fully integrated with the company Terminal. Our team’s systems are the gateway between the company and the financial industry, providing workflows for trading Interest Rate Swaps (IRS) and Credit Default Swaps (CDS), forming the largest buy-side electronic trading platform for fixed income derivatives.

We develop rich user interfaces which are powered by backend services in C++. As developers, we own the software end-to-end, and use a variety of technologies whilst practicing pragmatic innovation. Our software supports the entire trade process: displaying instrument prices on the company terminal, creation of trading tickets, and processing of over-the-counter negotiations. CDS and IRS are complex derivatives featuring many important financial details, and it is therefore essential for us to build products that allow our traders to see a lot of information while keeping our systems performant and flexible.

We collaborate closely with other teams in the larger Electronic Trading department and work daily with our business counterparts to move the platform forward and influence its direction. We are dedicated to sharing our knowledge regularly and to creating a collaborative environment. We are looking for software engineers who share our teams’ passion for delivering high quality software in a fast-paced client-driven environment.
