As a Principal Member of Technical Staff (PMTS), you will provide technical leadership and architectural direction for Salesforce’s Enterprise Knowledge Graph strategy. You’ll define the long‑term vision, architecture, and execution strategy for Knowledge Graph platforms, semantic technologies, ontology‑driven systems, graph data engineering, and AI‑powered developer productivity solutions. You’ll partner with Architecture, Product Management, Ontology, Data Engineering, and AI Platform teams to establish a scalable foundation that supports current and future agentic AI use cases.

• Define and drive the long‑term technical vision, architecture, and roadmap for Salesforce’s Enterprise Knowledge Graph platform.
• Lead architecture and design for knowledge graph ecosystems, including graph data models, ontologies, semantic layers, entity resolution frameworks, graph APIs, vector search capabilities, and retrieval architectures supporting AI and agentic use cases.
• Establish enterprise standards, governance models, engineering patterns, and best practices for Knowledge Graph development, deployment, and lifecycle management.
• Define strategies for integrating structured, unstructured, and third‑party data sources into graph‑based platforms using scalable data engineering patterns.
• Partner with Architecture, Product, AI Platform, and Data Engineering organizations to align platform investments with enterprise priorities and future AI initiatives.
• Drive technical direction for semantic routing, graph‑powered retrieval, enterprise search, agent orchestration, and federated knowledge access patterns.
• Lead evaluation, selection, and adoption of graph technologies, semantic platforms, vector databases, and AI infrastructure required to support enterprise‑scale workloads.

• Lead teams in product ionizing AI‑enabled engineering solutions, ensuring scalability, security, governance, reliability, and measurable productivity improvements.
• Provide technical leadership and architectural guidance across PMTS, LMTS, SMTS, and contractor teams while driving alignment across multiple organizations.
• Serve as the primary technical authority for complex architectural decisions, platform investments, and long‑term engineering strategy.
• Foster innovation and continuous improvement while establishing a culture of engineering excellence, technical rigor, and operational maturity.

• 12+ years of experience in software engineering, data engineering, distributed systems, enterprise data platforms, or related technical domains.
• A related technical degree is required.
• Proven experience defining and delivering enterprise‑scale Knowledge Graph platforms supporting AI, semantic search, data integration, and agentic applications.
• Deep expertise in Knowledge Graph technologies, ontology engineering, semantic modeling, linked data, graph databases, and enterprise metadata management.
• Strong hands‑on experience with graph technologies such as Neo4j, Top Quadrant, RDF/OWL, SPARQL, property graph models, semantic reasoning frameworks, or similar technologies.
• Proven experience leading the architecture and implementation of graph‑powered AI solutions, semantic retrieval systems, vector search platforms, RAG architectures, and agentic workflows.
• Demonstrated success in building, scaling, and product ionizing AI‑powered developer tools,…
