The Company

Demonware is a member of the Activision family of studios. We work alongside engineers and creatives at our AAA partner studios and deliver the online and data services required by our franchises. We craft, develop, and host services for some of the world’s biggest video game franchises, including Call of Duty and Crash Bandicoot.  


We are a technology-driven company with a commitment to openness. This means collaborating to solve problems, the freedom to talk to anyone, and the best idea wins. We take the work seriously; ourselves, not so much.


Demonware has offices in Dublin, Ireland; Vancouver, Canada; and Shanghai, China, and is a wholly-owned subsidiary of Activision Blizzard, Inc.


Big ideas, small egos.

Demonware hosts millions of concurrently connected users.  Technologies we use, but are not limited to, Python, Linux, MySQL, C++, and Erlang. We solve tough problems on a day to day basis, and interns have a big impact on what we do. We’ve had interns commit code and have it running in production within the first three days of joining.


We also like to have fun while we’re working hard. We dress casually, we have flexible hours, and we have kickass coffee.
