# AI Engineer, Ontologies & Knowledge Graphs

At Cadence, we hire and develop leaders and innovators who want to make an impact on the world of technology. We are looking for an engineer who builds the data and interface layer that makes complex software products programmatically understandable. Many powerful products expose rich but heterogeneous surfaces - source code, scripting APIs, file formats, data structures, and workflow logic. This role builds pipelines that extract and transform those surfaces into structured, queryable knowledge - designing the schemas, constructing the knowledge graphs, and exposing them through clean, typed programmatic interfaces for downstream consumption. Job Responsibilities Build ETL/ELT pipelines that extract data from source code, APIs, file formats, and documentation and load it into a structured knowledge store. Design and maintain schemas and semantic data models capturing entities, relationships, and capabilities. Construct and maintain knowledge graphs over heterogeneous product data. Develop source and metadata parsers (including source-code/AST parsing) to extract structure automatically. Build typed programmatic interfaces and data-access layers over the knowledge layer.
