Data Scientist

Rakuten Marketing is one of the largest digital advertising companies in the world. With offices on every continent, our company has gained the trust of the most famous global brands and developed a cutting-edge data-driven technology for online marketing.

Every day, we leverage the power of the Rakuten ecosystem data and of its 1.1 billion consumers around the world to identify audiences, optimize media buying, personalize ad experiences and maximize incremental revenue for our clients.

Our Data Science team in Paris works on developing new Machine Learning algorithms for acquiring audiences and maximizing client revenue with cross-device acquisition and advanced retargeting. Given the massive volume of information we have, traditional data processing methods are of limited help. This complexity calls for new technologies to efficiently analyse large sets of data and determine the statistical models that could most accurately predict the performance of our online marketing campaigns. The development of such technology is closely related to several fields of study:

  • Machine Learning modelling and Statistical simulation
  • Behavioural analysis and performance prediction
  • Data Management
  • Data Analytics
