About the Role

Our Software Engineers don't just write code, they solve real financial problems for millions of customers.

  • Building well-tested services and contributing to continuous delivery
  • Taking ownership of your work — from development to production
  • Continuously learning and developing your skills in a supportive environment

Who you are

  • You’ve got some solid hands-on experience with C# but open to learning Java or Kotlin
  • You care about writing good quality code and value clean design and testing
  • You’re curious, eager to learn and not afraid to ask questions

  • You want to build things that have a real impact on customers
  • You communicate clearly and are happy contributing to team decisions
  • You’re excited by modern engineering practices like CI/CD and cloud-native tools

Desirable:

  • Experience with fintech or banking is a plus, but we value problem-solvers from all backgrounds

  • 2-3 days a week in the office. We value face-to-face collaboration and a good work-life balance.
  • Option of working from abroad for up to 120 days a year!
  • 25 days holiday as standard, rising up to 30 days with tenure.
  • Private medical insurance through Vitality Health.

About [Employer hidden]

[Employer hidden] has been a pioneering force in the world of finance since 2005, lending out billions in personal loans since its inception, before the launch of its bank in 2020. Its depth of lending experience makes it a digital bank with a difference - offering all the benefits customers have come to expect from a challenger bank, but backed up by 16 years of know how.

[Employer hidden] has carved out a strong position for itself in UK fintech, offering more than just loans with products like savings accounts and credit cards. And its clear focus on lending and saving has paid off, with recent investment fueling both product growth and its entry into business lending. The bank also made its first acquisition, snapping up 'buy now, pay later' platform DivideBuy, as part of its expansion strategy.

On top of that, [Employer hidden] is now boasting two consecutive years of profit doubling, a rare feat in digital banking. Backed by fresh funding, it's now pushing into new territory with plans to launch a current account and integrate generative AI into customer services.
