Data Architect Knowledge Engineer – Euro-BioImaging (AI4Access)

Euro-BioImaging ERIC is a European research infrastructure providing life scientists open access to advanced imaging technologies expertise training and data services through almost 300 imaging facilities distributed among 40 Nodes across Europe. The Euro-BioImaging Hub is distributed across three sites: the legal Seat (Finland) the Med-Hub (Italy) and the Bio-Hub hosted by EMBL in Heidelberg.

The Euro-BioImaging Access Portal is the infrastructure interface that enables users to browse request and access imaging and image data technologies from an extensive and rich service portfolio. It is also the platform through which Euro-BioImaging and the service providing facilities manage the incoming access requests and user AI4Accessproject will develop a Research Navigator (anLLM application)integrated into the Euro-BioImagingAccessPortal to guide researchers to the right services workflows and resources across the infrastructure. A key foundation is astructured maintained ontology-alignedknowledge basethat can bequeriedreliablybythe Navigator.

Your role

We are looking for a technically strong colleague who will design set up and maintain thedatabase and data ingestion pipelineunderlying the AI4Access ontology-drivenknowledge basework with the Euro-BioImaging Bio-Hub team and community on the development of relevant ontologies and knowledge graphsanddeveloprobust technical interfaces between the knowledge base andtheResearchNavigator together with the Euro-BioImaging Seat team andwith the Euro-BioImaging Nodes own information and management systems.

Responsibilities include but are not limited to:

• Design and implementan ontology-aligneddata modelits technical representation (database schema versioning documentation)and theminimum viable service.
• Work with the Bio-Hub imaging specialists and Node-facing colleagues to translate real service descriptions into a maintainable structured form via community-agreed ontologies and/or controlled vocabularies.
• Support integration of semantic and metadata elements (controlled vocabularies identifiers/PIDs provenance) together with domain experts.
• Develop and maintainautomated ETL workflows to handle dataingestion pipelines(data collection inputs annotations transformations validation/QA rules repeatable updates)adapted to a diverse range of data and data sources.
