Project Contractor

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 focused on designing, building, deploying, and operating cloud-based identity services. You will contribute across backend APIs, cloud infrastructure, and frontend experiences — with React as the preferred frontend framework for new UI work. 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 strong full-stack fundamentals, cloud experience, and a responsible, methodical engineering mindset.

What You’ll Do

• Build and evolve backend services that support login, MFA, and client authentication
• Design and implement REST APIs using NestJS / TypeScript
• Build frontend experiences using React where new UI development is required
• Integrate with identity and MFA platforms (e.g. Transmit Security, Auth0)
• Deploy and operate services on AWS, using Infrastructure as Code
• Run and maintain services in production, including:
  • Database migrations and updates
  • Manage vendor-specific software services running in AWS
• 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
