Paris, Île-de-France Criteo Temps plein
What You'll Do: Join the Criteo AI Lab and help shape the future of product representation and retrieval across our ecosystem. As part of the group driving our core foundation model initiatives, you'll work on both applied research and robust engineering to power a wide range of tasks across search, recommendation and bidding. Once our prototypes and ideas show value, we push them into production: whether that means generating embeddings for billions of items, supporting large-scale retrieval indexes, or serving models under tight latency budgets. Our engineering teams ensure these models operate reliably and scale seamlessly.
  • Design and implement machine learning models for retrieval, ranking, and multimodal representation, tailored to our unique latency and scalability requirements.
  • Work with the agility of a medium-sized team and the reach of a company-wide platform. You'll move quickly on ambitious ideas and measure their impact through offline evaluations and online experiments.
  • Analyze large datasets, identify modeling challenges, propose solutions, build prototypes, and iterate quickly.
  • Stay current on academic and industrial developments in deep learning, retrieval, and foundation models, applying them to our specific product use cases.
  • Collaborate with experienced engineers to take models from prototype to production-quality systems used across multiple teams.
Who You Are:
  • You have a Master's or PhD in Machine Learning, Computer Science, or a related quantitative discipline.
  • You possess development experience in at least one mainstream programming language (Python, Java, C++, etc.).
  • You have a strong mathematical foundation and experience with Deep Learning
  • You are eager to tackle real-world scalability challenges and ideally have deployed ML solutions in production
  • If you're looking to make a tangible impact at the intersection of research and engineering—and thrive in a dynamic, high-stakes environment—we'd love to hear from you. Join us at Criteo and help shape the next generation of data-driven advertising solutions

We acknowledge that many candidates may not meet every single role requirement listed above. If your experience looks a little different from our requirements but you believe that you can still bring value to the role, we'd love to see your application​
