Not every iOS role is about polishing UI or shipping the next consumer app. This one is for an iOS engineer who enjoys owning the technical direction, working close to the platform, and dealing with the realities of performance, reliability and long-lived apps and SDKs in production. Despite the title, this is not a people-management role. It’s a hands-on position for a senior iOS engineer who wants responsibility, influence and interesting technical problems - without stepping away from code.

What you’ll be working on

  • Own the architecture and technical direction of iOS apps and SDKs
  • Design and build complex features using Swift, with some Objective-C and C++
  • Tackle challenges around networking, performance, stability and edge cases
  • Stay ahead of iOS and Apple platform changes, shaping how the team responds
  • Support SDK integrations and help resolve tricky production issues
  • Run design and code reviews, and help raise engineering standards
  • Make pragmatic use of modern tooling, including AI-assisted development tools, to improve quality and reduce busywork

Who this role suits

  • Like being the technical point of reference for iOS
  • Enjoy thinking about architecture and long-term platform health
  • Want influence and ownership without line management
  • Are comfortable going deep when things break in production

You’ll likely bring:

  • Strong experience building and shipping iOS apps in Swift (with some Objective-C)
  • Solid understanding of iOS networking (HTTP(S), TLS, sockets, proxies)
  • Experience integrating or working alongside native C++ libraries
  • Good knowledge of iOS SDK/API design, versioning and supporting external integrators
  • Familiarity with Apple Developer policies and how OS changes impact apps
  • Strong debugging skills (crashes, performance, battery) and sensible testing practices

How you’ll work

  • Hybrid role, Manchester-based 2 days per week in the office, the rest flexible
  • Flexible start and finish times
  • Full home-working setup provided
