Up to £85,000 + Benefits

Hybrid Working | London | 2 Days per Week in Office


We're working with a fast-growing WealthTech business that is transforming the way individuals and families engage with their finances through innovative technology and exceptional user experiences.

They're looking for a Full Stack Engineer to join a highly collaborative engineering team building and enhancing a modern web platform. This role is approximately 65% Frontend and 35% Backend, making it ideal for engineers who enjoy creating outstanding user experiences while remaining hands-on across the full stack.


The Role

You'll join a cross-functional squad responsible for delivering new features, improving platform performance, and helping shape technical decisions across the product.

The role has a strong frontend focus, but you'll also contribute to backend services and APIs, working within a modern cloud-native environment.

A key aspect of the engineering culture is the use of AI-assisted development tools, so candidates must already be comfortable incorporating AI into their daily workflow for coding, testing, and productivity.


Essential Requirements

  • Strong commercial experience with React
  • Strong commercial experience with TypeScript
  • Commercial backend development experience with Java
  • Experience working with Spring / Spring Boot
  • Hands-on experience using AI-assisted development tools as part of the software development lifecycle
  • Experience developing and consuming APIs
  • Understanding of software engineering best practices, testing, and clean code principles
  • Experience working within Agile environments


Nice to Have

  • Kotlin experience
  • AWS experience
  • Docker and Kubernetes
  • Microservices architecture
  • Event-driven systems (Kafka or similar)
  • GraphQL


What You'll Get

  • Salary up to £85,000
  • Hybrid working (2 days per week in London)
  • Private healthcare
  • Pension contribution
  • 25 days holiday
  • Regular team socials
  • Clear progression opportunities within a growing engineering organisation
