Job Description
The selected candidate for this position will report on-site 2-3 days a week.
We are seeking a strategic and technically proficient Principal Engineer Knowledge Graph to lead the design development and implementation of enterprise-grade knowledge graph solutions. This leader will be responsible for driving semantic data modeling graph-based AI/ML solutions and graph database architecture (with an emphasis on Neo4j) in support of our data and AI strategy execution.
The ideal candidate brings deep expertise in graph modeling and implementation ontology development graph machine learning and semantic technologies and is skilled in understanding business goals and requirements and reflecting them in systems implementations that consider current and emerging needs. You will collaborate across data science engineering and product teams to embed graph intelligence into enterprise systems using platforms like Neo4j and Databricks.
Duties and Responsibilities:
Lead the enterprise knowledge graph development and operationalization including data modeling ontology and taxonomy development semantic modeling and integration with machine learning and business platforms.
Design and manage complex graph data models and ontologies using W3C standards (RDF OWL SKOS SHACL) to support data standardization discovery and analytics.
Develop and implement graph-based machine learning models (e.g. GNNs link prediction GraphRAG) to support key business capabilities such as personalized learning intelligent search and recommendation systems.
Drive the use of NEO4J for graph data storage querying (Cypher) and integration into enterprise pipelines.
Collaborate with AI/ML engineers to fine-tune LLMs and integrate graph data into intelligent agents and semantic search systems.
Provide architectural leadership for semantic pipelines and Databricks integration supporting both batch and real-time graph analytics.
Champion the adoption of graph-based AI/ML especially in online higher education use cases.
