Pratt & Whitney is transforming the future of flight and is seeking a Lead Ontology & Knowledge Engineer to enhance their digital workforce. This role involves designing and implementing ontologies and knowledge graphs to support AI agents in performing complex reasoning and decision-making tasks.

Responsibilities

Develop and maintain enterprise-grade ontologies (OWL/RDF) that model the complex domain of aerospace engineering, manufacturing, and supply chain

Define the semantic schema for AI Agents, ensuring they share a common vocabulary when communicating across different business units (e.g., ensuring a "Task" in Engineering means the same thing to an agent in Operations)

Lead the architecture and deployment of our Enterprise Knowledge Graph

Build data pipelines (Python) to ingest data from legacy ERP systems, PLM software, and unstructured documents into the graph

Implement Entity Resolution and linking strategies to unify disparate data points across the organization

Collaborate with AI Engineers to design "Context Windows" for LLMs. You will determine what graph data needs to be injected into a prompt to maximize agent accuracy

Work on Causal Inference models: Structure data to help agents distinguish between correlation and causation (e.g., Did the maintenance delay cause the part failure, or did the part failure cause the delay?)

Establish semantic standards and data governance policies for the AI ecosystem

Evangelize the use of Knowledge Graphs within Pratt & Whitney, training other developers on graph-based thinking
