Mobile Developer

#iOS #Android

We’re looking for a junior/mid mobile developer and a senior mobile developer to join our team. You will participate in developing lots of cool mobile apps, both for our partners and Cobalt Sign, all while having a good time.

You will use Swift/Java or React Native for building quality native apps for Android and iOS. We care a lot for team spirit, well-organized projects and we also like to stay up to date with the newest technologies and practices.

We enjoy growing and improving our own mobile app – Ready Set Holiday – which has over 1 million downloads and reached a 4.5 store rating.

You can take a look at our Instagram feed to get a glimpse of our company culture, meet us – the “alchemists” – and browse the portfolio to see some of our work. If you agree with our office wall motto “Don’t stop until you’re proud”, drop us a line.

Tools we use and love💙

Xcode, Android Studio, Visual Studio Code, Bitbucket, JIRA, Confluence, HipChat, Basecamp, Trello, Skype, Workplace by Facebook

Company Culture


We enjoy sharing our passion for mobile development. We created Mobile Summer, a free and fun mobile development course for students.


We are fond of Zen Room, our own cozy place to relax, chat, play games or watch a movie.


We enjoy travelling, so our team-buildings are about visiting European capitals, seeing new places & new cultures.
