Senior Software Engineer - Identity & Authentication

About the role

In the European Client Identity team, we are building and operating Vanguard's authentication and MFA platform used by hundreds of thousands of clients across the UK and Europe. This is a hands-on senior full-stack role with a strong frontend focus. You will take ownership of the MFA web application - an Angular 21 + NestJS app that is the entry point for all UK Personal Investor clients. You will work in a highly regulated environment where security, reliability, and operational discipline matter. You don't need to be an identity expert on day one - but you do need Angular expertise, solid backend fundamentals, cloud experience, and a responsible, methodical engineering mindset.
