As an iOS Engineer, you’ll join a cross-functional squad working closely with colleagues across iOS, Android, Web, Backend, Product and Engineering.

  • Proactively identify blockers, inefficiencies and areas of unnecessary complexity, working with your squad to remove them and improve delivery.
  • Support others in the team through coaching, mentoring and knowledge sharing, helping create an inclusive environment where everyone can do their best work.

We'd love to hear from you if you have...

  • Experience building iOS applications using Swift, with an understanding of modern iOS development practices.
  • Familiarity with SwiftUI and UIKit, and ideally some experience working with Objective-C in an existing codebase.
  • A thoughtful approach to engineering quality, including testing, code review, maintainability and continuous improvement.
  • Experience working in a cross-functional product team, collaborating with engineers, product managers and other partners to deliver customer-focused outcomes.
  • The ability to contribute to technical decisions, explain trade-offs clearly and work collaboratively towards pragmatic solutions.
  • A proactive mindset, with the confidence to identify blockers or inefficiencies and help improve how the team works.
