Live Ops Experts Breathing New Life into Old Games DECA Games uses their unique approach to live operations to breathe new life into games on the decline. The team works with games studios and developers who lack the resources to handle the responsibilities of running a game as a service. DECA Games provides a way for developers to profit from the long tail of games and enhances the experience for a game’s dedicated fanbase with their long term approach to games as a service. They handle all community management, product management, feature development, art, customer support, live events and promotion planning to ensure a high quality integrated service.

Job description

About DECA Games

We believe that games should be played for decades but many are abandoned even when a loyal community is screaming to keep them alive. DECA specializes in acquiring games from other developers and reinvigorating them to continue to entertain for decades. When other studios see an old game, we see an amazing set of problems to solve and a huge opportunity.

DECA is a remote company with over 230 people in over 26 countries globally. DECA has been profitable since our inception in 2016. DECA is also a part of the Embracer Group, the largest public gaming company in Europe.

About our culture

We’ve managed to maintain a small company feel with the stability and resources of a much larger one. We fully believe in the flexibility of a remote workplace. Employees are trusted to manage their time and get things done independently. We believe that egos and politics need to be checked at the virtual door. That means no jerks are allowed, that no job is too small for anyone, and an openness to help and learn from each other is required. We love the challenge of working within constraints and love when we succeed as a team. Check out more about us and our values on our website (www.decagames.com).
