As a Senior RAD (Rapid Action Development) Developer in our Rates development team, you will work in close partnership with quant researchers, traders, and technology teams. The role sits at the intersection of front-office trading and technology, with direct ownership of the tools traders rely on daily. This is a hands-on position suited to someone who thrives in a fast-paced trading floor environment and wants genuine proximity to the business.
As a Senior Developer you will build, maintain, and enhance the desk’s proprietary tools — including bespoke spreadsheets and Python-based applications — ensuring traders have reliable, performant infrastructure for pricing, risk management, and PnL analysis. You will collaborate with quant research to translate model changes into production tooling, work alongside strategic technology partners on platform integration, and act as a first point of contact for desk-side technical issues. Priorities shift quickly, and the ability to triage, communicate, and deliver under pressure is essential. You will need to maintain, upgrade and improve the existing software to latest software and hardware versions recommended.
