What this job is about

We are looking for an experienced Android Developer who can help us in our Mission to build a sustainable power supply in Africa.

Our Tech-Stack

  • Technologies at the core of our apps: RxJava, Realm, FCM, Retrofit, Dagger, AutoValue extentions, Android Job, OrmLite.
  • Interest in learning Kotlin

You don't have to be familiar with all of these, but if you are - that's definitly a plus!

Your Perspective

  • Doing something meaningful - you´ll becoming part of an enterprise, that brings real positive impact to ordinary people in East Africa
  • Personal development – beside new experiences of developing in an international context with new technologies we support you with possibilities for participation on Hackathons, developer conferences and classical trainings
