Senior iOS Engineer focused on Swift, SwiftUI, and moving logic into Kotlin Multiplatform (KMP) shared layers.
Compensation
20,000 - 28,000 PLN gross per month on an employment contract
Responsibilities
Lead the design, development and maintenance of scalable, high-performance iOS applications using Swift, SwiftUI and Xcode, following The Composable Architecture (TCA) and a modular Swift Package Manager codebase.
Work hands-on in our Kotlin Multiplatform shared layer — consuming and extending shared Kotlin UseCases, repositories and models exposed to iOS through the KingfisherFoundation framework and helping grow the amount of logic that lives in shared code.
Collaborate with Android and backend engineers to shape the Swift-facing API of the shared KMP layer so it serves both platforms cleanly and help define our long-term multiplatform mobile strategy.
Integrate and maintain our GraphQL (Apollo Kotlin) and REST (Ktor) data layer — including the iOS URLSession/Ktor bridge and normalized caching, and third-party SDKs and platforms.
