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.

Expected graduation between January 2027 and May 2028

Available for an 8-month, in-person co-op starting September 2026

Clear written and verbal communication

Portfolio is required
