To support our desire to make an impact with our app, we are looking for a mission driven

Android developer (32 - 40 hours)

Building the sustainable bank in your pocket

We are currently working on several major projects to improve our mobile app. Our ambition is to have an app that allows our customers not just to do their daily banking with ease, but also to get insights on the impact of how they spend their money. This involves a migration to native technology and adding new “impact” features. You’ll be closely collaborating within your own Scrum team and also with the other teams in our mobile domain and teams of other domains. Teams autonomously deliver features, all the way from understanding what’s needed to deploying a new version to the app store.

To deliver high quality software with high frequency we value clean code, a solid architecture and design for test. We use MVVM and Kotlin and rely on TeamCity for our CI/CD pipeline. Testing is done with Junit and Espresso. Our API is generated for both iOS and Android. We don’t use third-party social SDK’s as we like to keep big tech out of our app.

We offer you an environment where you collaborate with and learn from other Android developers.


This is you

  • You have at least 1-2 years of experience developing Android apps.
  • You have some experience with a part of our tech stack.
  • You always cover your code with unit tests and have experience with UI tests.
  • You enjoy building screens and thinking about end user experience.
  • You keep yourself up to date with the latest developments around Kotlin and the Android ecosystem.
  • You are always looking for ways to improve your skills in both technology and team collaboration.
  • You have a sharp mind and pragmatic attitude. You value keeping it (stupid) simple.
  • You take initiative and you understand which decisions you can make yourself and when you need to consult with another experienced developer or software architect.
  • Your way of working is based on mutual respect. You can easily get things done and involve your colleagues in what you want to achieve.
  • Pre:
    • Experience with build tools, build configurations and project modularization.
    • Experience with coroutines.
    • Knowledge of jetpack compose.
    • Dutch speaking

The team

You are going to work in the App domain, currently consisting of 4 development teams working in native technologies (Android and iOS). Each team has 3 Android developers, 3 iOS developer, a tester and a product owner. You’ll be closely working together on the features in the app and align your work with the iOS devs and other teams. Knowledge sharing is one of our team values.

Every two weeks all the Android developers come together in the Android chapter to share ideas on how to move forward with the Android app, share best practices and discuss improvements for the architecture and design of the app.

We currently have a hybrid app that is a combination of native script technology and native technology. Our ambition is to move to a completely native app.
