Lead Android Engineer

About Dyson and the Role

Dyson develops the Dyson Link Smart Home app, a leading IoT platform integrated with over 3 million Dyson devices worldwide and used actively by more than 1 million users. The app enjoys high ratings of 4.5 stars on the App Store and 4.3 stars on Google Play. The company aims to expand this platform as it connects more devices across various categories, posing significant technical challenges.

We are seeking a Lead Android Engineer to join our mobile development team. This senior individual contributor role demands deep technical expertise, strong ownership, and the ability to influence cross-functional teams. The ideal candidate will help shape the Android platform's architecture and technical trajectory while driving engineering excellence and leading complex initiatives.

Technical Environment and Technology Stack

Our Android application is architected modularly, primarily following the MVVM design pattern. The majority of the codebase is written in Kotlin, with ongoing migration from Java. We utilize modern Jetpack libraries such as Navigation Component for UI flow management and WorkManager for background processing.

For networking and APIs, the app employs Retrofit, AWS IoT SDK, and Gson, with Dagger used for dependency injection. Kotlin coroutines are extensively used to handle asynchronous operations and event streams.

Our testing framework includes JUnit and Mockito for unit tests and Espresso with Kakao for UI testing. We continually assess new tools and frameworks to enhance productivity and maintain code quality.
