What they need

Context

The Europe Data Team at CMA CGM is responsible for delivering end-to-end data platforms, data products, and analytics capabilities for the European Regional Office. Working closely with business stakeholders, IT teams, and Head Office, the team delivers secure, scalable, and business-driven data solutions.

In the European region, delivery often occurs in a transitional environment where global data platforms or products are not yet fully deployed. As a result, regional data products and intermediate solutions are developed to meet immediate business needs while ensuring alignment with future enterprise platforms.

Within this context, Data Engineers must combine strong data platform expertise, delivery pragmatism, and business orientation. Solutions must be:

- Delivered rapidly
- Designed for scalability and reuse
- Aligned with enterprise data architecture (Snowflake, governance models)
- Built with maintainability and future integration in mind

The Europe Data Team is currently accelerating the development of regional data products, data pipelines, and analytics platforms to support business visibility, KPI tracking, and operational decision-making. We are therefore looking for a hands-on Data Engineer to design, build, and maintain scalable data solutions supporting these initiatives.

Missions

As a Data Engineer, you will:
