Qualifikationen

• Proven experience in enterprise, information, data, or semantic architecture within complex enterprise environments.
• Deep expertise in ontology engineering, knowledge graphs, semantic modelling, taxonomies, controlled vocabularies, and enterprise information models.
• Strong knowledge of RDF, OWL, SKOS, SHACL, SPARQL, validation, provenance, and related semantic standards.
• Experience designing layered and federated architecture models across enterprise, domain, country, and use case levels.
• Strong understanding of ontologies, data models, source-system models, physical schemas, and graph-based representations.
• Knowledge of GraphRAG, semantic retrieval, entity linking, structured reasoning, LLM grounding, and Agentic AI architectures.
• Experience with APIs, event-driven integration, data platforms, distributed systems, and semantic services.
• Strong communication and stakeholder management skills, with experience in insurance or other regulated industries considered an advantage

Aufgaben

• Define and maintain the target architecture for enterprise ontologies, knowledge graphs, controlled vocabularies, semantic services, and ontology-driven AI capabilities.
• Establish the ontology layering model across enterprise, domain, country, and use case levels, including ownership, inheritance, extension, localization, and reuse principles.
• Define standards for semantic modelling, classifications, relationships, constraints, naming, versioning, validation, provenance, and lifecycle management.
• Drive the integration of ontologies and knowledge graphs with the Agentic AI Platform, including GraphRAG, Vector RAG, agent runtime, MCP tools, memory, and source-system access.
• Define patterns that combine semantic context with documents, operational and analytical data, process context, and agent runtime state.
• Review ontology designs, semantic integration concepts, graph models, and domain or country extensions to ensure alignment with enterprise standards.
• Identify reusable concepts and semantic patterns while ensuring standardization only where cross-domain or cross-country reuse provides value.
• Maintain reference architectures, implementation guidance, architecture decisions, non-functional requirements, and technology assessments for ontology and graph capabilities
