Senior Software Engineer - Titles


Demonware creates and provides the online services behind hugely popular video game franchises such as Call of Duty and Skylanders. We do matchmaking, microtransactions, and data analytics for almost half a billion users. Demonware has offices in Dublin, Ireland; Vancouver, Canada; and Shanghai, China, and is a wholly-owned subsidiary of Activision Blizzard, Inc.

Demonware’s Titles department is responsible for developing, launching and maintaining services for some of the world’s largest gaming franchise such as Call of Duty. We are looking for an experienced engineer to join this department to work on a new class of free-to-play AAA titles, leveraging many of the existing technologies created by Demonware and develop new online services to support the specific locales and challenges of the free-to-play market.

Most of our services are developed using Python and C++ and we use many supporting technologies such as MySQL, Redis, RabbitMQ, and Cassandra. Our development is geared towards low-latency and large-scale distributed systems that can handle millions of concurrently connected users with average response times of < 100 ms.

As well as building large scale systems, we expect our experienced engineers to be able to mentor and grow others in the organisation. We are looking for someone who enjoys software engineering challenges and the opportunity to pass on that experience to others.
