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).




- Data Integration ETL Develop scalable robust data pipelines and ETL processes to ingest transform and map diverse data sources into the graph structure while ensuring data quality and integrity.
- Querying and Analytics Write complex high-performance graph queries (e.g. Cypher SPARQL) and develop advanced graph analytics and algorithms (e.g. shortest path community detection) to extract insights.
- 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.
