About the job Android Developer

Senior Android Developer

Catawiki’s purpose is to enable people to discover and obtain special objects that help them fulfil their passions. In doing so, we add some colour and make the world a more interesting place.

Our Android Story

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 on how we structure our code base.
We embrace change, we’ve migrated from MVC to MVP and now to MVVM. Currently, we are adopting Kotlin and enjoying all the cool advantages that come with it. We are constantly improving our architecture, making it fun and challenging at the same time.

Here’s Ahmed, one of our Engineers:

“It is so inspiring to have been a part of Catawiki’s journey and to see how the company has grown and continues to do so. We’re always aiming to improve our products of which our Android App is, of course, a big part of. To do so, I collaborate on a daily basis with Backenders, Product Owners and Designers to find the best way to implement features technically, as well as visually. We have come a long way since the birth of our Android App, and we still have a long way to go, but we are excited and motivated to continue improving and learning along the way”.

So what's the job?

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 6 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 Java but we are strongly adopting Kotlin for our new features and refactorings. Our app uses MVVM as a general architecture, and we rely heavily on the reactive/functional paradigm using RxJava. We also make use of Android’s Architecture Components. We are using the most popular stuff like Dagger 2, Retrofit, data binding, as well as Mockito and Espresso for testing.

You'll move in sync

You will be part of one of the Product teams, working on a given domain (Search & Discovery, Payments, Onboarding etc.) and you will work closely with all of the team members (Front-End, Back-End, UX and Data) in sharing your expertise and explaining how the things you do will affect the user experience.

A little about you

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

Familiarity with consuming RESTful APIs

Next to this, it’s likely you’ll also have experience with the Kotlin, RxJava, UI testing and A/B testing

The Catawiki Story

A piece of the moon, a complete dinosaur skeleton, the Pope's hat, the world's smallest book - at Catawiki, we come across exceptional objects such as these every single day. Our mission is to make special objects available to everyone.

In fact, 14 million users are buying and selling on Catawiki every month. This means we are continually growing and always on the lookout for new talent.

Born and raised in The Netherlands, we started in 2008 as a platform where collectors could manage their collections online. Yet, times change, ideas evolve, and in 2011 we hosted our first online auction and we haven’t looked back since! We’ve now grown to 500 Catawikians working across 7 International offices and are proud to have maintained our startup mentality.

Here’s what we can offer you

A diverse and international team with over 40 different nationalities, located in the heart of Amsterdam and Assen with an easy-going atmosphere. The Catawiki Community gathers everyone together for everything from ‘CataFooty’ to International Food Festivals, Friday Drinks, Board Game Nights, Pub Quizzes and Boot Camps!

And there’s more! We also provide paid holidays, holiday allowance and a pension plan paid for by Catawiki.


Catawiki is committed to building a diverse company and diverse teams. That includes everyone, no matter your age, ability, gender, race, religion or sexual orientation. We welcome applications from underserved and underrepresented communities. If you’ve got a story to tell, come and join us.
