Who we are
Criteo (NASDAQ: CRTO) is the global technology company powering the world’s marketers with trusted and impactful advertising. 2,800 Criteo team members partner with over 20,000 customers and thousands of publishers around the globe to deliver effective advertising across all channels, by applying advanced machine learning to unparalleled data sets.

The Site Reliability teams keep one of the largest computing platforms in the AdTech world functioning like clockwork. They are processing, storing and monitoring through large scale data compute & storage services (Hadoop, SQL & NoSQL), streaming (Kafka), platform as a service (Chef, Mesos), identity management (Kerberos) and analytics (Hive, Druid, Vertica).

Core-services team builds the current and next gen platform to consume resources on Criteo infrastructure. We are building the platform as-a-service for all stateless and stateful applications in Criteo (think webservers, database, distributed file systems). We use Apache Mesos to achieve that vision.
We spend time to understand our client needs and help them launch hundreds of instances of their apps across the world, isolated using containers and connected through our internal service mesh using Consul.
