Who we are
 
At Criteo, we connect 1.2 billion active shoppers with the things they need and love. Our technology takes an algorithmic approach to determining what user we show an ad to, when, and for what products. Our dataset is about 40 petabytes in Hadoop (more than 30 TB extra per day) and we take less than 10ms to respond to an ad request. This is truly big data and machine learning without the buzzwords. If scale and complexity excite you, join us. 
Challenges of this role
At Criteo we face some of the most challenging and interesting problems in the advertising software industry.
