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.

- Build and evolve frontend experiences for login, MFA, and client authentication using Angular

- Integrate with identity and MFA platforms (e.g. Transmit Security, Auth0)
- Deploy and operate services on AWS, using Infrastructure as Code
- Database migrations and updates
- Manage vendor‑specific software services running in AWS
- Run and maintain services in production, including:
- Write automated tests and contribute to improving test coverage and quality
- Participate in CI/CD pipelines, deployments, and operational procedures
- Work closely with product and security stakeholders to translate requirements into
- Technical solutions
- Continuously improve engineering standards, tooling, and reliability
What it takes
- Proficiency in Angular (v14+) — you will own and onboard others onto an Angular 21 codebase
- TypeScript across frontend and backend
- Experience with Angular component libraries and design systems
- Solid Node.js backend experience, with NestJS or Express for REST API development
- Understanding of authentication protocols: OAuth 2.0, JWT, MFA flows
- Hands‑on experience with AWS (ECS, Lambda, CloudFront, S3, Secrets Manager)
- Familiarity with Infrastructure as Code (CloudFormation or Terraform)
- Experience with containerised workloads (Docker)
- Strong Git practices and CI/CD experience (GitHub Actions or similar)
Nice to have
- Experience with identity, authentication, or MFA systems
- Familiarity with Kong API Gateway or similar
- Exposure to Aurora PostgreSQL or DynamoDB
- Knowledge of microservices architectures
- Exposure to security concepts (IAM, encryption, networking)
- Experience with observability tooling (OpenTelemetry, Honeycomb, Grafana)
- Experience in regulated or enterprise environments
