Ontology Knowledge Architect

About the role

The group you’ll be a part of, Enterprise AI, is building the foundation for Lam’s AI-first future. We partner across business, data, engineering, security, and technology teams to create scalable AI platforms, governed agent architectures, AI-ready knowledge assets, and reusable solution patterns that help Lam accelerate innovation, improve operations, and turn proprietary domain expertise into durable enterprise advantage.

Responsibilities

• Define and evolve Lam’s enterprise ontology and semantic architecture across business objects, relationships, decisions, actions, permissions, events, and AI-ready knowledge assets.
• Hands-on design and implementation of reusable patterns that connect source systems, data pipelines, metadata, semantic models, knowledge graphs, AI Search, vector stores, MCP tools, and agent orchestration frameworks.
• Partner with business domain experts to model enterprise domains, processes, decision flows, operational states, and domain-specific knowledge for use by agents, copilots, applications, analytics, and automation.
• Create standards for ontology-data integration, including schema mapping, master-data alignment, graph design, metadata enrichment, lineage, observability, versioning, and access control.
• Establish architecture for AI-ready knowledge assets, including structured and unstructured knowledge, semantic analysis, knowledge extraction, embeddings, retrieval, and feedback loops.
• Design how MCP servers, APIs, tools, data services, and agent actions should be represented, secured, governed, and connected into ontology-aware AI workflows.
• Collaborate with AI solution architects, data architects, platform engineers, security, IAM, governance, and domain teams to ensure agents operate with grounded context, trusted actions, and appropriate human oversight.
• Evaluate emerging ontology and knowledge platform capabilities and recommend patterns that balance speed, interoperability, portability, cost, governance, and long-term enterprise differentiation.
• Build reference architectures, standards, decision frameworks, implementation patterns, and governance models for ontology and knowledge lifecycle management.

Requirements

• Bachelor’s degree in Computer Science, Information Systems, Data Science, Engineering, Mathematics, or a related technical field; Master’s or PhD preferred.
• 12+ years of experience in enterprise architecture, data architecture, knowledge architecture, semantic modeling, AI architecture, or related technical leadership roles.
• Hands-on experience designing and implementing enterprise-scale data, semantic, ontology, or knowledge graph architectures across complex business domains.
• Strong understanding of data pipelines, data integration, metadata, lineage, governance, access control, data quality, and data product design.
• Experience with ontologies, taxonomies, semantic models, graph models, knowledge graphs, business object models, or domain-driven design.
• Familiarity with modern cloud data and AI ecosystems such as Microsoft Fabric, Azure, Databricks, Synapse, AI Foundry, graph databases, vector stores, search platforms, or comparable technologies.
• Experience building AI-ready knowledge patterns for LLMs, copilots, retrieval-augmented generation, agent orchestration, semantic search, or decision-support applications.
• Understanding of MCP, API-based tool integration, agent-tool interaction patterns, and security/governance considerations for AI systems that access enterprise tools and data.
• Ability to move fluidly between strategy and execution—creating architecture direction while also working directly with teams to implement, validate, and refine it.
• Strong communication skills, including the ability to influence senior leaders and create clear architecture artifacts, standards, and roadmaps.

Preferred Qualifications

• Experience with ontology or operational AI platforms such as Palantir Foundry / AIP, Microsoft Fabric / Fabric IQ, or comparable enterprise semantic and AI platforms.
• Familiarity with enterprise manufacturing, semiconductor, supply chain, engineering, product lifecycle, quality, finance, or operations domains.
• Experience designing and delivering architectures for agentic AI systems, including grounded context, memory, tool use, action governance, feedback loops, and human-in-the-loop controls.
• Strong understanding of security, IAM, least privilege, auditability, and responsible AI principles for enterprise AI systems.
• Ability to balance near-term delivery with long-term architecture direction in a rapidly evolving AI landscape.
