Middle+ Full-Stack Developer Required | iGaming / Casino Games
We are looking for a Middle+ Full-Stack Developer to join our team, which creates its own casino games from scratch. For us, a game is not just an interface. It should feel alive and dynamic: smooth animations, sound, character reactions, clear states, and that elusive "one more round" effect. At the same time, behind the beautiful gameplay, there should be precise server logic, stable real-time performance, and fair game mechanics that users can verify themselves through Provably Fair. We are looking for someone with strong React / Next.js skills, who is also confident in writing Node.js backends and is ready to influence the product not only from the UI side.

▪️ What you'll be doing in the first few months The main task is to collaborate with the team in creating and bringing our own casino games to market: from game mechanics and server logic to animations, sound, and final UX.
