Desired Qualifications

• Active TS/SCI with CI Polygraph
• Master's degree or PhD in Computer Science, Data Science, Information Science, or a related field; PhD preferred. 
• Experience integrating semantic data layers and knowledge graphs directly with LLM-based systems, including prompt augmentation, context injection, and agentic workflow orchestration. 
• Expertise in graph database platforms (such as Neo4j, Amazon Neptune, TigerGraph, or equivalent) and experience deploying graph assets at enterprise scale. 
• Experience with MLOps, DataOps, or platform engineering practices for managing data pipelines and model serving infrastructure.
