The Role:

As an iOS Developer (12 month contract), you will be a critical contributor to the entire Kobo iOS app. You will take ownership over key features, and deliver them from inception to completion. We pride ourselves in a collaborative environment, and you will have input over future product direction and features.


You will be joining the iOS team within the Global Apps group. We have recently re-written our iOS app in pure Swift/SwiftUI. While most of the code inside the app is new native Swift code, the app incorporates some legacy React Native components (such as the reading experience). There is an existing React Native team to maintain these components, with integration and support provided by the iOS team as needed.

  • Contribute new features to the Kobo App
  • Fix issues and maintain the quality of the codebase

  • Excellent problem-solving skills and attention to detail
  • Strong communication and collaboration skills

Nice to Have Qualifications

  • Experience with a unidirectional architecture such as The Composable Architecture (TCA) or similar patterns.
  • Strong functional programming fundamentals
  • Previous UIKit and Objective-C experience, although our app is fully written in Swift/SwiftUI.
  • Experience with modularization (Swift Package Manager) and CI improvements.

The Perks:

  • Flexible hours and hybrid remote working environment
  • Weekly Kobo Spark sessions
