Data Engineer - People (f/m/d)

Paris, Paris, France

The Data People Team is looking for a Data Engineer in Paris

The Data Engineer mission is part of the integration project of the solution chosen by the Corporate HR Domain (Workday) and its deployment for the 65 countries in which Decathlon is located. You will join the project team under the functional responsibility of Data Migration within the Data stream.

As a Data Engineer, you will be responsible for transforming locally collected data to make it available to the integrator in charge of deploying the platform. You will work closely with multidisciplinary teams to ensure data integrity, quality, and security.
