Project Description
We are seeking a highly motivated and detail-oriented Semantic Data Modeler to join our innovative team. In this role, you will design, develop, and maintain semantic data models that form the backbone of intelligent data integration, knowledge discovery, and reasoning in complex domains such as life sciences. This position sits at the crossroads of data modeling, semantic standards, graph technologies, and AI-driven workflows, enabling advanced knowledge representation and data interoperability.
If you are passionate about connecting the dots across complex data ecosystems, thrive on precision and structure, and have a natural ability to think in terms of graphs, hierarchies, and relationships, this role is for you.
Responsabilities
1. Semantic Data Modeling
- Design and maintain ontologies and vocabularies using RDF, RDFS, OWL, SKOS / SKOS-XL, DCT, DCAT, and many other standard ontologies
- In collaboration with Business Analysists, translate business concepts into semantic models that support interoperability and reasoning
- Ensure semantic models align with web standards (W3C, FAIR) and industry standards (CDISC, SNOMED CT, etc)
- Apply validation logic and language (SHACL or ShEx) to ensure model and data quality
2. Graph Data Management
Model, store, and query data in graph databases (triple stores and property graph systems)Use SPARQL and other graph query languages (e.g., GraphQL, Cypher, Gremlin) to retrieve and manage knowledge graphsOptimize graph data pipelines for scalability, performance, and accuracy3. Data Transformation & Integration
Design models as integrative parts of implement ETL / ELT pipelines to automatize knowledge extraction from structured and unstructured data into semantic / graph-based systemsIntegrate semantic models to NLP techniques for semantic enrichment / annotation of text-derived knowledgeCollaborate with data engineers and scientists to ensure smooth ingestion and alignment of heterogeneous datasets4. Quality & Governance
Define semantic data governance practices ensuring consistency, traceability, and reusabilityDocument modeling choices, schema evolution, and semantic mappings thoroughlyContribute to metadata standards and data stewardship practices5. Collaboration & Continuous Improvement
Work in an Agile / Scrum environment, delivering iterative improvementsCollaborate closely with cross-functional teams (data engineers, scientists, domain experts, AI specialists)Contribute to DevOps and MLOps practices in semantic pipelines6. Business Acumen :
