Full- stack engineer

Who we are

we connect 1.5 billion active shoppers with the things they need and love. Our technology takes an algorithmic approach to predict what user we show an ad to, when, and for what products. Our dataset is about 50 petabytes in Hadoop (more than 120 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.

What is like to work in our R&D?

Criteo’s Product Engineering teams are responsible for building the client-facing products that make Criteo tick.
We're an industry leader in machine learning and deep learning, working on feature extraction, model definition, prediction, recommendation and dynamic creatives. From those we build high scale, real time, low latency systems, serving over 3M QPS, handling over 200 billion http requests on a daily basis. Last, we create the applications, APIs and UIs which provide first class service to our clients & partners (retailers, brands & publishers).
