What You'll Do:

CRITEO is looking for a Senior Machine Learning Engineer to join our R&D team in Paris. Our mission is to power real-time product ranking systems that deliver the most relevant ads to users on retailers’ websites as part of our Retail Media solutions (c.f. ).

To achieve this, we design and operate large-scale machine learning systems built on tabular data to predict user behaviors such as clicks and purchases. Our work spans the full ML lifecycle — from building robust data pipelines and developing production-grade models to monitoring and maintaining model performance in production.

You’ll join a team of Machine Learning Engineers working closely with cross-functional partners across R&D, Product Management, Product Analytics, and Commercial teams to deliver impactful, scalable solutions.

Our core technology stack includes Python, Spark, SQL, and C#.
