Lead Android Engineer

About Us We own and develop the MyDyson mobile app, which is at the forefront of Dyson's IoT experience. We are proud of what we have built so far; we have more than 2 million active users worldwide and our IoT platform has over 8 million connected Dyson machines. We have huge ambition to grow this platform and as we connect more machines from more categories, the challenge is significant. About the Role We are looking for a Lead Android Engineer to join our mobile team at Dyson. This is a senior individual contributor role for someone who combines deep technical expertise with strong ownership and influence. You will play a key role in shaping the architecture and technical direction of our Android platform, driving engineering excellence, and leading complex initiatives across teams. You are highly collaborative, thrive in ambiguity, and take pride in building scalable, maintainable systems while enabling others to do the same. Our Tech Our app has a modular architecture and is built using the MVVM pattern. Our codebase is primarily Kotlin, with an ongoing effort to migrate remaining Java components. We leverage modern Jetpack libraries to accelerate development and reduce boilerplate, including Navigation Component for UI flows and WorkManager for background tasks. For networking and APIs, we use Retrofit, AWS IoT SDK, and Gson, alongside Dagger for dependency injection. Given the asynchronous nature of our application, we make extensive use of Kotlin coroutines to model and manage event streams. Our testing stack includes JUnit and Mockito for unit testing, and Espresso with Kakao for UI testing. We continuously evaluate and adopt tools and frameworks that improve developer productivity and code quality.
