Are you passionate about eSports and are you up for the challenge of building a platform that integrates gaming, betting and sports to create a surprising and fun solution to the users? Join us as a Software Developer!

At Playfulbet you will find great teamwork in an agile environment. We care about software quality and maintainability, so we promote the use of practices like continuous integration, daily gem updates, code reviewing and frequent refactoring.

Our infrastructure is composed of Cloudflare, Haproxy balancers (5 front and 3 servers in the background) and all physical machines in Hetzner. All software is our own development in Rails 4.2 with Redis, Mariadb and Elasticsearch 1.7.
