Data Engineer Lead Expert H/F

In the context of an Agentic AI transformation within a major group, the semantic layer is identified as an intermediary layer between data sources and end users or consuming systems. Its role is to abstract underlying data structures (tables, column names, joins) into a business-friendly vocabulary including concepts, definitions, relationships and rules that can be interpreted by both humans and machines.

The semantic layer is identified as a key component to enable LLM-based agents to interpret data in a trustworthy manner and to support the scalability of Agentic AI across multiple use cases.

Objectives of the mission :

The mission aims to explore entities and implement an initial approach for a semantic layer, including its related tools and technologies, based on selected Agentic AI use cases.
