About you
We’re waiting for you to join our team! To make this collaboration as long and productive as possible, please consider our requirements for the position:
- Strong Ruby language knowledge. We tend to believe the Ruby Association Certified Ruby Programmer Examination. Questions for self-assessment can be found here.
- SQL language proficiency. We’re working with various types of databases daily (you’ll most likely deal with MongoDB, MariaDB and Redis while working in Bookmate).
- Familiarity with engineering culture and collaborative development skills. We’re very proud to say that every developer who worked with Bookmate was a very qualified engineer, asked a lot of right questions and was able to work in a highly professional team of experts.

Hence the ability to learn how our business works and what problems we are dealing with on a daily basis.
- A good level of written English (ideally, closer to B2). Being able to speak is a huge bonus. As an international company, we communicate in English.
