Biorce is poised to redefine the landscape of healthcare, shaping a future where innovation and accessibility converge for the betterment of humanity.

About the role

We are seeking a Senior Research/AI Engineer with specific expertise in Knowledge Graphs (KGs) and their synergy with Large Language Models (LLMs). This role is critical for building a structured knowledge foundation that enhances our AI solutions, adding context, reasoning, and explainability to our Generative AI systems.

Key Responsibilities:

Key Responsibilities:

• Design and Ontology Engineering: Design and evolve the formal ontology and semantic models (e.g., RDF, OWL) for our knowledge graph, accurately capturing complex domain knowledge and relationships.
• Graph Development & Implementation: Design, build, and optimize the knowledge graph architecture using graph database technologies (e.g., Neo4j, JanusGraph, Amazon Neptune).
• Querying and Analytics: Write complex, high-performance graph queries (e.g., Cypher, SPARQL)
• Collaboration: Work closely with Data Scientists, ML Engineers, Product Managers, and domain experts to translate business requirements into technical knowledge graph solutions that power search, recommendations, and AI/ML applications.
• Performance Tuning: Monitor, analyze, and optimize the performance of the graph database and associated pipelines for scalability and real-time query speed.

Essential Requirements:

• Minimum of 3+ years of hands-on experience in designing and implementing large-scale Knowledge Graphs in a production environment.
• Deep expertise in ontology engineering, semantic modeling, and experience with standards like RDF, RDFS, OWL, and SPARQL.
• Proficiency with at least one major graph database (e.g., Neo4j, TigerGraph, AWS Neptune).
• Practical experience integrating LLMs with Knowledge Graphs (e.g., RAG, KG-powered AI agents).
• Strong programming skills in languages essential for data engineering, primarily Python.
• Experience applying NLP techniques for text processing and structuring (NER, relation extraction).
• Excellent problem-solving skills and the ability to work collaboratively in a fast-paced, agile environment.
• Excellent communication skills and ability to articulate complex AI concepts to diverse audiences.
