As an AI Ontology Knowledge Architect at Lam Research, you will join the Enterprise AI team to build scalable AI platforms and governed agent architectures that drive innovation and operational excellence. Your role involves defining and implementing enterprise ontology and semantic architecture across various business domains, creating reusable patterns for data pipelines and knowledge graphs, and partnering with domain experts to model processes and decision flows. You will translate architectural concepts into practical implementations, establish standards for ontology-data integration, and ensure AI systems operate within governed boundaries. This hands-on role requires expertise in semantic modeling, graph technologies, cloud ecosystems like Microsoft Fabric and Azure, and a deep understanding of data governance and security principles. Experience with enterprise manufacturing or semiconductor domains is beneficial, as you will work on agentic AI systems that require robust memory, tool use, and human oversight mechanisms.
