We are looking for Java developers, from experienced seniors to hands-on principal engineers, to join long-term greenfield projects with a leading financial institution in London.
You will be part of small, high-calibre engineering teams delivering strategic rebuilds and modernisation projects, replacing legacy systems with clean, cloud-aligned solutions built on Java and modern engineering practices. These are not maintenance roles - they are about writing great code, solving challenging problems, and shaping architecture from the ground up.
You will be joining teams working on genuinely greenfield, strategic rebuilds with clear scope, autonomy, and modern tech stacks. There is little to no BAU work, and plenty of room to shape architecture, influence direction, and own your contributions end-to-end.
This is a great opportunity to deepen your Java expertise, work alongside highly capable engineers, and gain exposure to large-scale systems and distributed architectures within major financial organisations with no prior banking experience required.
This is a collaborative, trust-based environment where developers have real autonomy, clear ownership, and meaningful technical input. There is a genuinely friendly culture in the team - people take pride in their craft and support each other to deliver excellent software.
Creating a (non AI-based) software rewrite platform. The platform will be based on OpenRewrite. The first project to rewrite will be Talend data transformation job to move the implementation away from Talend.
Requirements for the candidate

- Very good command of Java + Spring Framework
- Knowledge and experience with OpenID Connect

Would be plus
- Virtualization / containerization / cloud technologies
