How we work

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, having 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.

What you’ll do

Here at Catawiki, you will have a huge impact, working in a data-driven way to add value to the business along with the other 4 members of the Android team. You will add your own expertise to further grow our business, experiment, and innovate the product.

You’ll be adding new features to create an even greater experience for our users, as well as actively collaborating with your fellow Android developers to take the codebase and the entire Android App to the next level. Our millions of users will thank you for that!

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

As an Android Engineer, you bring a strong track record of shaping tech stacks beyond your immediate team. At Catawiki, you’ll continue to influence company-wide Android development, collaborating across teams and contributing to cross-functional features.

You’re deeply familiar with Android and enjoy supporting peers, both in day-to-day work and within our Android Platform team. You assist the Platform Lead, contribute to stack improvements, and offer long-term coaching to fellow engineers.

You’re also experienced in drafting RFCs and opportunity proposals, clearly articulating technical problems, trade-offs, and solutions. You confidently engage with Product Managers, UX Designers, and other Tech teams to drive impactful decisions. As a passionate engineer, you bring these values to Catawiki:

• You are a passionate, experienced Android Developer with a strong eye for detail.
• You strive to be a great team player and don’t shy away from new challenges.
• You are comfortable in a startup environment and are ready to jump in and help if needed.
• You keep the company's values close to your heart and enjoy being in a diverse environment.

We expect you to have experience with:

• Strong Object-oriented programming skills - priority
• Strong knowledge of the Android framework
• Proficient with Kotlin
• Proficient with Compose
• Knowledge of the reactive/functional paradigm
• Familiarity with MVVM architecture
• Familiarity with consuming RESTful APIs
• Unit testing

Additionally, experience with RxJava, UI testing, and A/B testing is likely to be beneficial.

Our Offices and Way of Working

Our vibrant offices in Amsterdam, Paris and Lisbon are designed to inspire and connect. Most Catawikians are within commuting distance of one of our offices and enjoy the flexibility of a hybrid work model. 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.
