About Demonware

Demonware is a member of the Activision family of studios, partnering with engineers and creatives across AAA game studios to deliver the online and data services that power some of the world’s biggest franchises — including Call of Duty and Crash Bandicoot. We’re a technology company that values openness and collaboration. We believe the best ideas win, everyone should feel empowered to contribute, and while we take our work seriously, we don’t take ourselves too seriously. At Demonware, you’ll find big-company challenges with a small-company culture. We support millions of concurrent users and work with technologies such as Python, C++, Java, Linux, MySQL, Erlang, and Kubernetes. Our co‑op students make real contributions — many see their code running in production within days of joining.
