On behalf of Ciklum Digital, Ciklum is looking for a Senior Ruby on Rails Developer to join our team on a full-time basis.

About the Project:

Babbel is driven by a mission: Everyone. Learning. Languages. This means building products that help people connect and communicate across cultures. Babbel and Babbel for Business focus on using a new language in the real world, in real situations, with real people. And it works: Studies with Yale University, City University of New York and Michigan State University prove that it gets users talking with confidence.

The key is a blend of humanity and technology. A team of linguistic experts hand-craft each of our courses, to provide content that is constantly adapted to our learners’ needs. Interactive content with videos and podcasts makes understanding a new language easy, because Babbel is for everyone. That’s why our team is as diverse as our content. From headquarters in Berlin and New York, 750 people from more than 65 nationalities represent the backgrounds, characteristics and perspectives that make all humans unique. Making a true connection with millions of paid subscribers across the globe is what makes Babbel the most profitable language learning app worldwide.

Babbel in Numbers:

The #1 top-grossing language learning app globally
Millions of active paying subscribers
More than 60,000 lessons 14 languages hand-crafted by 150+ linguists
More than 10,000 hours of learning content
Over 70 learning podcast episodes and over 50 hours of video learning content
As part of our team, we’ll collectively tackle all things engagement: how do we make sure that learners are always challenged, but never overwhelmed? That everyone coming to Babbel feels welcomed? That everyone feels motivated to pick up the app and learn something every single day?
