Building the sustainable bank in your pocket

Our ambition is to have an excellent banking app for all people that choose sustainable banking. On top of stable, secure and performing daily banking functionality, we want to establish meaningful communication with our customers and stimulate positive change. We are looking for you, if you can take the lead on the technical side and shape a high-quality solution together with PO’s, devs, UX and, possibly back-end teams and solution architects. Also, we are on a DevOps kind of mode of operation, so you should be able to find your way around various applications and organizational units in order solve the issues we and our customers face. After just having finished our migration to native apps, we’re now bringing much requested features to our customers. 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. Our Android app is built with MVVM, Kotlin and Jetpack Compose. We rely heavily on TeamCity for our CI/CD pipeline and testing is done with Junit and Espresso. Our API is generated for both iOS and Android and no third-party social SDK’s in our app.


The team

You are going to work in the app domain, currently consisting of four development teams working in native technologies (Android and iOS) and a couple of UX designers. Each team has three Android developers, three iOS developers, a tester and a Product Owner/Information Analyst. You’ll be working closely together and align your work with the PO and other teams. Knowledge sharing, accountability and trust are a couple 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. As a lead developer you’re likely to be involved in cross-platform alignment with iOS and collaborations with back-end teams as well.
