Job description


You’ll join a cross-functional product team building and evolving a large-scale iOS application used by millions of users. This is a senior-level role in a high-traffic, business-critical environment, where reliability, performance, and clean architecture are essential.

You’ll work closely with backend engineers, product managers, and designers, owning features end-to-end while helping set the technical standard for iOS development within the team.

WHAT WILL YOU BE DOING:

  • Design, build, and maintain production-grade iOS applications using Swift across UIKit and SwiftUI codebases
  • Deliver features in a continuous delivery environment, shipping small, incremental changes to production
  • Collaborate closely with backend teams to integrate APIs and evolve client-server contracts
  • Work with UI/UX designers to translate designs into scalable, accessible, and high-quality mobile experiences
  • Write well-tested code, including unit and integration tests, and contribute to test automation
  • Participate in code reviews, refactoring, and architectural discussions
  • Help define and evolve iOS best practices, patterns, and tooling across the team
  • Mentor and support other engineers, explaining not just how things are done, but why
  • Actively contribute to Agile ceremonies and continuous improvement initiatives
  • Identify and escalate technical risks or impediments early, helping drive pragmatic long-term solutions

WHAT WE ARE LOOKING FOR:

  • Strong commercial experience building iOS applications in Swift
  • Solid experience working with UIKit and exposure to SwiftUI in production environments
  • Good understanding of iOS architecture patterns (MVC, MVVM, VIPER, etc.)
  • Experience integrating with RESTful APIs, working with JSON, and client-server communication
  • Hands-on experience writing unit tests (XCTest) and a quality-first engineering mindset
  • Familiarity with CI/CD pipelines for iOS (e.g. Fastlane or similar tooling)
  • Strong knowledge of Git and collaborative development workflows
  • Strong English communication skills
  • Experience working with Objective-C and bridging legacy code with Swift

NICE TO HAVE:

  • Experience with SwiftUI at scale or reactive frameworks such as Combine.
  • Exposure to high-traffic consumer applications
  • Experience with performance optimisation, crash monitoring, or mobile observability
  • Previous mentoring or technical leadership experience

    WHAT’S IN IT FOR YOU?

    • Be part of our collegial environment where responsibility and authority is shared equally amongst colleagues and help create our company culture
    • A culture in which we don’t criticise failure but ensure we learn from our mistakes
    • An Agile environment where your ideas are welcome
    • The possibility to grow and experience different projects
    • Fully remote work
    • Ongoing Training & Mentoring
    • Learn and experiment with new solutions
    • The possibility of travelling
