The company is a global technology provider delivering data analytics and AI-powered solutions that help organizations better understand customer behavior, optimize marketing performance, and make informed business decisions. The project is focused on building a large-scale Knowledge Graph and Identity platform that models relationships between audiences, content, brands, devices, and behavioral data. Responsibilities: Owning the end-to-end design, development, and versioning of core RDF/RDFS/OWL ontologies and SHACL validation frameworks. Defining ontology standards, derived-attribute schemas, aggregation/scoring logic, and governance practices aligned with W3C and relevant industry standards. Leading ontology design reviews and translating business requirements into scalable knowledge graphs and semantic data models. Co-designing derivation and transformation pipelines with Data Engineering using Databricks/Spark, including schemas and validation checkpoints. ## Kogo szukamy Must-haves: Bachelor's degree in Computer Science, Information Science, Computational Linguistics, Mathematics, or related fields. Hands-on experience in ontology engineering, semantic data modeling, or knowledge graph development for 5+ years, with a demonstrable track record of production ontologies at scale. Deep expertise in W3C semantic web standards: RDF, RDFS, OWL, SPARQL 1.1, and SHACL. Hands-on experience building and validating graph schemas in a production triplestore (Amazon Neptune, Stardog, GraphDB, Jena, or equivalent). Strong Python, including production-quality, well-tested code; comfortable building data pipelines and graph processing workflows. First-principles understanding of description logics, ontology design patterns, and the practical trade-offs between OWL expressivity and triplestore scalability. Hands-on experience with entity resolution, record linkage, or deduplication at scale (mapping messy, multi-source real-world data to clean ontological representations). Strong communication skills, ability to defend ontological modeling decisions in design reviews and explain trade-offs to non-specialist stakeholders. Level of English – from Intermediate+ and above. ## Benefity **Zdrowie:** - Pakiet medyczny **Kuchnia:** - Kawa / Herbata ## Lokalizacje - Rondo Daszyńskiego 1, Warszawa, Polska ## O firmie — Andersen Lab **Wielkość firmy:** 5000+ **Strona WWW:** https://andersenlab.com Andersen – your global software development partner Andersen is a global software development company with over 18 years of experience supporting businesses worldwide in their digital transformation.
