Backend Developer


We aim for versatile and flexible teams with 4 - 8 team members. They work together on the features of our customizable product bundle. You can start with any specialization, but we expect you will grow to a full-stack developer able to deliver any work fragment. This happens organically, as a result of iterative development, the variability of tasks and team self-organization. You will have support from colleagues specialized on Quality Assurance, UX, and Product development, so you can focus on the areas you know best, and which make you happiest to work on.


We develop one of the most technologically complex solutions on the market and we ♡ Javascript. Node.js is a backbone (no pun intended) of our backend related work.. In most of projects we use cutting edge technologies like React, Redux, Sagas and Flow/TypeScript. You may also find a Google Closure Tools and CoffeeScript in our older projects. These technologies communicate with scalable data storages like MongoDB, PostgreSQL, HBase and Elasticsearch and many more.. We have implemented a Continuous Integration system, so you will know that the code you are working on passed the tests, and, if you break it, that it would be easy to fix. The whole process is implemented on Gitlab and automated tests. Our more than 100 APIs clearly point to our microservices religion. You will learn to love them and write them, too.
