Java Back-end Developer for OneTouch

As a member of the Yolo family (formerly Coingaming), OneTouch mainly centers on game development, including table, slot and Live Dealer games. We started operating in 2015 after spotting a large gap in the market for premium quality mobile table games that passionately and meticulously embrace a mobile-first approach to design. 

With this vision in the forefront of our minds at every point of the game creation process, we have successfully developed a suite of retina-ready mobile table games that are hugely popular in both of our main markets – Europe and Asia. 

We are now looking for a mid-level Back-end Game Engine Developer to join our team of 50 dedicated professionals. Our philosophy for back-end development is: stable, scalable and supportable which is achieved through simplicity, convention and cunning. While we are expanding, we are keen to remain dynamic and highly supportive internally.
