Android Developer

As an Android developer you will be building the customer-facing product to file tax returns on Android mobile phones. You will be involved in important product decisions and work closely with the whole team to create elegant and reliable user interfaces. We’ve made progress on the iOS app and backend, but we’ll need your help to make the Android app feel at home in the Android ecosystem.
Since it’s a new project, you’ll get to make the calls on architecture, libraries, minSdkVersion, and so on. Interested in Kotlin? Sure! Let’s get that going.
We’re using React Native in the iOS app for the view layer. Don’t let that worry you, though, as a big part of the app is still a native iOS product. So, even though we’d want to keep using React Native for Android also, be aware that your Gradle, your RecyclerViews, your RxJava knowledge is as necessary as ever.
