Semantic AI Engineer - Remote Work

About the role

Join BairesDev as a Semantic AI Engineer to build the foundation of a neurosymbolic AI system that delivers deterministic, trustworthy outputs. You will design a bounded domain ontology and create pipelines that transform heterogeneous data into a structured, typed graph.

Key responsibilities

• Design a bounded domain ontology from reference data, defining entity types, relationships, cardinality and shape rules.
• Build entity resolution and semantic alignment pipelines to map model‑generated concepts to canonical ontology entities.
• Implement formal constraint reasoning for satisfiability, contradiction detection and counterexample generation.
• Develop SPARQL and RDF store operations behind an encapsulated semantic API.
• Design evaluation and reproducibility engineering, including accuracy metrics, ontology coverage and reproducibility guarantees.

Required profile

• 8+ years of experience in data science, ontology engineering or semantic modeling.
• Production‑grade proficiency in Python for building pipelines and engineering‑grade code.
• Strong background in formal constraint reasoning and experience with SMT solvers such as Z3.
• Advanced proficiency in English.

Required skills

• Python
• RDF 1.1, OWL 2, SHACL
• Entity resolution and semantic alignment
• Z3 or similar SMT solver
• SPARQL and RDF store operations (e.g., Oxigraph, Apache Jena/Fuseki)
