About Our Mobile Developer Contract Roles in Cardiff
What does a mobile developer contractor do?
As a contract Mobile Developer, you are hired to build, maintain, and improve applications for iOS and Android mobile platforms, either working natively in Swift or Kotlin on a single platform, or using cross-platform frameworks such as React Native or Flutter to develop applications that run across both platforms from a shared codebase. Contract engagements arise across all sectors where mobile products are commercially important, from consumer-facing fintech and retail apps to enterprise mobility solutions and healthcare applications. Contractors are brought in to build new mobile applications, to deliver major feature releases, to migrate from an older mobile technology to a modern stack, or to provide additional senior mobile engineering capacity within a product team during a period of intensive delivery.

Native iOS developers are expected to be proficient in Swift and increasingly SwiftUI, with UIKit experience for maintaining older applications. Native Android developers need strong Kotlin skills alongside Jetpack Compose for modern UI development.

Flutter contractors need Dart language proficiency and familiarity with Flutter's widget system and state management approaches. Across all mobile platforms, experience with app store submission, mobile CI/CD pipelines, crash reporting tooling, and the performance optimisation techniques specific to mobile environments is expected at senior level.
