Android Developer

Global migration is a 21st-century reality: Whether people are fleeing from something or racing towards better opportunity, finding love, or looking to experience new cultures, people are now living side by side in a new way. At Rebtel, we believe in tearing down borders – from the geographical borders that complicate international communication and money transfers to the cultural borders that keep people divided. We’re on a mission to build products serving the 2 billion modern internationals of the world. We offer work, communication, and remittance services for anyone that has crossed a border:
Our team mirrors our global audience: we are a diverse team of people from 18 different countries that get together everyday – and we’d love for you to join us. Do you have what it takes?

Rebtel is looking for an Android Developer
About Rebtel Android
The work is well structured without being stifling. We use an agile workflow to handle day to day tasks. We also practice code review as it's an excellent way to spread knowledge and to keep code quality high. You will find tasks that are demanding and tasks that will trigger your creativity.
In an environment as complex as Rebtel, refactoring is important to keep the code base clean. A healthy portion of time is dedicated to this. We have started to integrate Kotlin into the existing code bases and will soon begin to move the entire application to Kotlin.
The Front-End development team is up to date with development best practises and software patterns. We have quick communication channels between teams and have regular hackathons.
