Technical Lead – Core Services & Game Servers

About Online Services & Online Tech Foundation 

Online Services (OS) is Ubisofts central organization responsible for developing and operating the shared online capabilities that power our games tools and internal platforms. We build essential systems such as identity notifications content management automations Game Servers orchestration matchmaking telemetry and more enabling Ubisoft teams to deliver online features and live experiences to millions of players worldwide. 

We collaborate with game productions internal technology teams and global publishing groups to ensure our online ecosystem is reliable scalable secure cost-efficient and developer friendly. 

Online Tech Foundation (OTF) is the engineering backbone behind these capabilities. OTF defines and maintains the platforms cloud infrastructure architectural standards and foundational tooling used across Online Services. OTF champions API-first development cloud-native design shift-left testing DevSecOps automation observability and operational excellence. 

Joining OTF means contributing to the engineering foundations that shape the future of Ubisofts online ecosystem.
