At Catawiki, we keep our users close to our hearts and make sure that we deliver a great user experience across all platforms. 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.

We embrace change, we’ve migrated from MVC to MVP and then to MVVM. Currently, we are embracing Kotlin, Coroutines and Compose - enjoying all the cool advantages that come with it. We are constantly improving our architecture, which makes working at Catawiki fun and challenging at the same time.

How we roll - Our Stack

Our codebase is primarily written in Kotlin and has very minor traces of Java as we continue to adopt Kotlin for all new features and refactors. 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.

What you’ll bring

Our Offices and Way of Working

Our vibrant offices in Amsterdam, Paris and Lisbon are designed to inspire and connect.

This means that you will be in the office 2 out of 5 days (40% of your working time) to collaborate and connect with your colleagues. That said, some roles may be an exception : if the job description states that the position is fully remote or 100% office-based, that arrangement will apply instead.
