## Description

You will also be supporting and modernising a range of middle and back office systems, including reference data and FIS platforms. You'll be working closely with database and reporting teams, and collaborating downstream with Front Office on changes, challenges and projects. The team is midway through a cloud migration programme - bringing systems up to current standards and moving on-prem workloads into AWS, with a real focus on smart modernisation rather than a like-for-like lift. Candidates must be expert Java Developers with real-world cloud migration experience with AWS.
