Job Description:

Digital Application Developers | Rathbones | London, Glasgow or Liverpool

I’m working with Rathbones on 3 permanent Digital Application Developer opportunities, and we’re looking for strong software engineers who want to build customer-facing digital products rather than simply maintain existing applications.

The key thing to know about this search:

You don’t need to be a web + iOS + Android expert.

Rathbones is looking to hire the best engineers first and build the right balance of skills across the team.

We’re particularly interested in people who have:

  • Built greenfield applications/products from scratch
  • Developed customer-facing web applications, portals or mobile apps
  • Strong hands-on experience with React / TypeScript, iOS/Swift/SwiftUI or Android/Kotlin
  • Experience building and integrating APIs and application services
  • Strong software engineering fundamentals around testing, CI/CD, architecture and secure development
  • Experience working closely with Product, UX/UI, Architecture and Data teams
  • Ideally, experience within Financial Services, FinTech or another regulated environment
  • Exposure to AI coding/development tools such as GitHub Copilot, Claude Code or Cursor is a bonus

The team is building and enhancing digital capabilities across web and mobile, supporting client and adviser experiences across areas including investment, onboarding, reporting and servicing.

So whether you’re:

  • A strong React/TypeScript engineer with excellent product development experience
  • An experienced iOS/Swift engineer
  • A Full Stack Engineer with strong frontend/mobile capability

…I’d be interested in speaking with you.

London (up to £88,000) | Glasgow (up to £75,000) | Liverpool (up to £70,000)

If you’ve built something from the ground up and enjoy solving complex problems in a product-focused engineering environment, I’d be keen to hear from you.
