Mobile Developer Jobs

A mobile developer builds and maintains the apps on people's phones — banking, retail, transport, health. The day-to-day work means writing features against a design spec, wiring screens up to back-end APIs, fixing crashes flagged in the bug tracker, and shipping through TestFlight or the Play Console. Most of it happens in a squad with a product owner and a designer, on two-week sprints, with code reviews and CI pipelines (Bitrise, GitHub Actions, Fastlane) running on every push. Native developers split into iOS and Android; cross-platform shops run one team for both.

The stack splits along platform lines. iOS work is Swift and, increasingly, SwiftUI, in Xcode, with older Objective-C still around to maintain. Android is Kotlin and Jetpack Compose in Android Studio, with some legacy Java in older codebases. Cross-platform roles call for React Native or Flutter, and Kotlin Multiplatform is growing fast — developer-survey adoption roughly doubled over the past year. Across all of them, employers expect Git, REST and GraphQL, an MVVM-style architecture, local storage (Core Data, Room, SQLite, Realm) and automated testing.

UK salaries vary by experience. Junior roles run roughly £28,000–£38,000, mid-level £40,000–£60,000, and seniors £65,000–£85,000, with London paying a premium and lead or mobile-architect titles reaching £90,000–£110,000. Contract day rates sit around £300–£500 for mid-level and £400–£800 for senior. Fully remote posts exist, but hybrid — two or three days on-site in London, Manchester, Leeds, Birmingham or Bristol — is the common pattern. Progression runs developer to senior to lead or mobile architect, then splits into engineering management or staying hands-on as a principal.
