Lead Data Engineer

Paris, France.

Rakuten Marketing's Data Engineers design the tools that make it possible to process the huge amount of data we receive every day. In close collaboration with our Data Scientists, they help develop 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:

  • Data Management and Expertise
  • Big Data cluster-computing frameworks
  • Data processing for Machine Learning modelling
  • Data Analytics


  • Elaborate complex datasets from open source big data framework such as Hadoop or Spark.
  • Work on large scale distributed infrastructures, either internally or on the cloud (Amazon Web Services, Google Cloud…).
  • Design new automated and efficient tools that will be the heart of our data architecture for the coming years.
  • Constantly control the coherence of the delivered results. This will require a deep understanding of our platform on both a technical and a business side.
  • Interact closely with our technical teams (Data Science, Business Intelligence, DSP Innovation, Architecture) to share and obtain advanced knowledge.
  • Write detailed and precise documentation of your work.


  • Graduated from a Scientific or Engineering School or a Master's program in Computer Science or Machine Learning with a Big Data specialization.
  • Experience/knowledge with Spark and Scala is required.
  • Knowledge of at least one object-oriented language (Java, C++, ...)
  • Previous experience in the web industry is highly recommended.
  • Interest in e-commerce and new technologies.
  • Good English skills.
