Description du poste

ETNIC, the IT operator of the Wallonia-Brussels Federation, is seeking an Expert Data Architect for an assignment supporting Wallonie-Bruxelles Enseignement (WBE). The mission is to analyze the existing data landscape, produce its mapping, and create conceptual and logical domain models. The architect will translate business framing into data requirements and models. The role works closely with business analysts, enterprise architects and solution architects.

The consultant will assess several target architecture options, including data hub, lakehouse, data mesh, data fabric and virtualization, without imposing a predetermined target. The role will define data architecture principles and usage rules for exchange and exposure patterns such as APIs, event-driven approaches, replication, virtualization and analytical feeds. Security, personal-data protection, sovereignty and digital-sobriety constraints must be translated into enforceable architecture rules. Architecture choices will be documented to support a collective decision.

The assignment also covers governance prerequisites, including roles, bodies, metadata, cataloging, access rights and implementation of the “only once” principle. The architect will build a prioritized roadmap, work packages and transition architectures aligned with the AIGLE program schedule. Workshops, decisions, open points and recommendations must be documented. Knowledge transfer will ensure that ETNIC and WBE teams can continue using the deliverables after the assignment.
