With every app download and new feature, we face the challenge of scaling our backend and infrastructure to meet the requirements of our customers. Ruby (JRuby, MRI), Rails, a service-oriented architecture and our handpicked database technologies help us reach this goal. Your responsibilities as part of the team will be:

  • Conception and implementation of new social, geo-based or health features
  • Design of next generation, efficient and reusable backend services as well as APIs
  • Development of highly available, fast and scalable solutions

There will also be plenty of opportunities to bring in your own ideas and thereby help the department develop further.


  • Degree in Information Technology, Software Engineering or a related field (higher technical institute or university)
  • Expertise with backend development and enthusiasm for Ruby (first practical experience is a plus)
  • Understanding of databases, for example, MySQL, MongoDB, Cassandra – We use those among others!
  • Preference for talking to clients in JSON or binary
  • Very good English skills both written and spoken OR very good German and at least basic English
  • Willingness to learn, to build cool stuff and to work in beautiful Linz, Salzburg or Vienna (Austria)
