Context

The team is looking for a new Data Scientist based in Lille or Paris.

The team, part of the Data Supply Chain, is responsible for the design, development, and maintenance of innovative analytical and Artificial Intelligence solutions around supply chain use cases such as multi-echelon demand forecasting, target stock estimation, or shortage management, to name a few. You will work within a multidisciplinary team composed of Data Scientists, Data Analysts, Analytics Engineers, and ML Engineers, working in an agile manner and in close proximity with Product and Engineering contacts as well as business users.

Missions

Your Mission: Analyse, Develop and Deploy Inventory Optimization solutions at scale

As a Data Scientist, you will play a pivotal role in bridging the gap between business strategy and high-quality technical implementation within the Inventory Optimization team. Your mission is to develop and deploy production-grade ML models for demand forecasting across BTB and BTC channels on different geographical granularities (stores, warehouses), directly contributing to stock management optimization. You will work on building robust models, collaborating with a multidisciplinary team of data experts, and partnering with Product and Business stakeholders to translate business requirements into scalable, reliable reality.
