What is a semantic web?

A Semantic Web job involves working with technologies that enhance data interoperability and meaning on the web. Professionals in this field use standards like RDF, OWL, and SPARQL to structure and link data, making it machine-readable and semantically rich. Roles may include developing knowledge graphs, ontologies, and linked data applications to improve search, AI, and data integration. These jobs are common in industries like AI, research, and enterprise data management.

What does a semantic web professional do?

A Semantic Web professional typically spends their day designing semantic data models, developing ontologies, and implementing standards like RDF and OWL to structure and link complex information. You may work closely with data scientists, software engineers, and subject matter experts to ensure data interoperability and support knowledge-driven applications. Tasks often include writing SPARQL queries, integrating heterogeneous data sources, and collaborating on system architecture or solution design. This role frequently involves staying updated with the latest Semantic Web standards and tools, ensuring that data solutions are robust, scalable, and aligned with organizational needs.

What are the key skills and qualifications needed to thrive in the semantic web position?

To thrive in a Semantic Web role, you need a strong background in computer science, expertise in data modeling, ontologies, and RDF/OWL, often supported by a relevant degree. Familiarity with semantic technologies such as SPARQL, Protégé, and graph databases, as well as certifications in linked data or Semantic Web technologies, is highly beneficial. Strong analytical thinking, problem-solving skills, and the ability to work effectively in interdisciplinary teams are standout soft skills. These abilities are crucial for designing, implementing, and maintaining systems that enable smarter data integration and retrieval across complex datasets.

Job description

Position Summary

Design and implement semantic/knowledge architecture enabling AI-driven reasoning across the drug discovery and development lifecycle.

Mission

Build the semantic foundation for AI systems to reason across discovery, preclinical, clinical, and post-marketing domains while preserving scientific meaning, provenance, and translational fidelity.

Key Responsibilities
  • Semantic Architecture & Knowledge Modeling: Design/maintain enterprise knowledge models (discovery biology, toxicology, safety pharmacology, pathology, clinical development, pharmacovigilance, real-world evidence); create conceptual/logical/physical models for AI-enabled discovery.
  • Ontology Engineering & Governance: Lead ontology strategy, development, governance, lifecycle management; curate/extend biomedical ontologies; establish governance/quality/semantic review; ensure consistency, provenance/traceability, and FAIR principles.
  • Knowledge Graph & Reasoning Infrastructure: Build RDF-based knowledge graph architectures; develop semantic mappings/inference rules/reasoning frameworks; enable GraphRAG, semantic retrieval, AI agents, reasoning; ensure semantic interoperability.
  • Translational Data Harmonization: Create semantic bridges across SEND, SDTM, ADaM, MedDRA, HPO, MONDO, SNOMED CT, FHIR, OMOP, Cell Ontology, Protein Ontology.
  • Cross-Functional Leadership: Partner with stakeholders and engineering/platform teams; influence enterprise semantic strategy.
Required Qualifications
  • PhD or Master’s in Biomedical Informatics, Bioinformatics, Computational Biology, Computer Science, Information Science, Knowledge Engineering, or related.
