Senior Java Developer for Casumo (Kyiv)





The story of Casumo
In 2012 we set out to create a great gaming experience. We quickly realised that success in building a new product was co-dependent on designing a dynamic work environment and creating a culture in which a great product could flourish. To this day, our product is a result of these synergies and it’s what makes us unique.

The Casumo brand
We believe that when people are entertained, they become happier. And that’s the basis upon which the Casumo brand was built. We want our players to be proud of playing at Casumo and to feel like part of a fun-loving community that shares the same passion for quirky humour and play. We believe in winning hearts instead of winning customers and it’s our brand that enables us to make that happen.
