Android is no exception! As an Android developer working at Catawiki, you are empowered to take full ownership of the features we deliver and full ownership of how we structure our codebase.</p> <p>We embrace change, we’ve migrated from MVC to MVP and then to MVVM.

Our app uses MVVM as a general architecture, and we rely heavily on the reactive/functional paradigm - moving from RxJava to Coroutines. We also make use of Android’s Architecture Components. We are using the most popular 3rd parties like Dagger 2, Retrofit, as well as Mockito/MockK and Espresso for testing.</p> <h3><strong>What you’ll bring </strong></h3> <p>As a Senior Android Engineer, you bring a strong track record of shaping tech stacks beyond your immediate team.
