Ciklum is looking for an Expert Ruby on Rails Developer to join our team full-time in Ukraine.

We are a custom product engineering company that supports both multinational organizations and scaling startups to solve their most complex business challenges. With a global team of over 4,000 highly skilled developers, consultants, analysts and product owners, we engineer technology that redefines industries and shapes the way people live.

About the role:

As an Expert Ruby on Rails Developer, become a part of a cross-functional development team engineering experiences of tomorrow.

The platform is the top-selling language learning solution.

Driven by a purpose — to create mutual understanding through language — it builds products that help people connect and communicate across cultures. Through self-study lessons, instructor-led live classes, business solutions, a podcast series, and a magazine, users can focus on using a new language 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 to speak with confidence.

The key is a blend of humanity and technology. More than 60,000 lessons in 15 languages are handcrafted by over 200 linguists, and user behavior is constantly analyzed to shape and improve the learner experience. A team of linguistic experts handcrafts each of the courses to provide content that is constantly adapted to learners’ needs. Interactive content with videos and podcasts makes understanding a new language easy because it is designed for everyone. That’s why the team is as diverse as the 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 this platform the most profitable language learning app worldwide.

Platform 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 ensure that learners are always challenged, but never overwhelmed? That everyone feels welcomed? That everyone is motivated to pick up the app and learn something every single day?
