Clearing Full Stack Developer

Hybrid Working - London -50% a week on site.

Financial Services

Lorien's leading banking client is looking for an experienced Full Stack Developer to join a major greenfield technology programme within Financial Services.

You will be part of a team building a brand-new Asset Servicing platform, replacing both an existing legacy internal system and a US-based vendor solution. This is a long-term transformation programme offering the opportunity to work across modern front-end, BFF and microservices-based backend technologies.

The role requires genuine full-stack development experience, although candidates can be stronger on either the front-end or backend.

The ideal candidate will be a hands-on Full Stack Developer who is comfortable working across Angular/React, TypeScript/Node.js, Java microservices and SQL. You may naturally lean towards either front-end or backend engineering, but you will have sufficient experience across the stack to contribute to the end-to-end solution.

Previous experience building platforms within Financial Services and particularly Asset Servicing or settlement environments would be a significant advantage.

This role is based in London.

This role will be Via Umbrella.
