We are a major global banking organisation working on the next generation of our institutional banking platforms. This is a Front-End Engineering role first and foremost, and we are looking for experienced Front-End Developers / Design Engineers who are hands-on and comfortable working directly from requirements rather than primarily from completed Figma designs. The role is based in London on a hybrid basis, with 2 days a week in the office, for an initial 6-month contract. The work supports complex institutional banking functions including global payments, FX, treasury services and client connectivity, with a focus on highly functional, efficient and accessible user experiences rather than heavily visual consumer-style interfaces. The rate is £425/day for mid-level and £525/day for senior candidates, inside IR35.
