You are equally comfortable whiteboarding an ontology with a domain expert and pushing graph schemas to production alongside an ML team. You see the world as a graph, and you believe that well-structured knowledge is the foundation of truly intelligent machines. You thrive on translating complex, messy real-world knowledge into clean, reasoned, machine-readable structures that AI agents can act on - and you bring the rigor, curiosity, and collaboration to do it at scale. The Work You will embed directly with clients as a trusted technology advisor and hands-on engineer - leading the architecture and development of knowledge graphs, ontologies, and semantic data models that power next-generation agentic AI systems at enterprise scale. Responsabilities * Own the end-to-end design, governance, and maintenance of enterprise-scale knowledge graphs and ontologies, bridging structured domain knowledge with large-scale agentic AI pipelines to enable reasoning, planning, and decision-making. * Develop and govern ontologies, taxonomies, and semantic data models that formalize domain knowledge and support interoperability across systems and teams. * Define and enforce data modeling standards, schema design patterns, and best practices for structured and semi-structured knowledge representation. * Translate complex domain knowledge from subject matter experts into formal, machine-readable knowledge structures using RDF, OWL, SPARQL, or property graph models. * Lead knowledge engineering discovery workshops and working sessions with client stakeholders to surface, validate, and formalize domain knowledge requirements. * Collaborate with AI/ML engineers to integrate knowledge graphs as grounding and context layers for LLM-based agentic pipelines and retrieval-augmented generation (RAG) systems. * Design knowledge structures that support multi-step agent reasoning, tool use, and dynamic planning across heterogeneous data sources. * Work with project teams, team leaders, delivery leads, and client stakeholders to create standout Data & AI offerings powered by graph-based technologies. * Collaborate with data engineering and platform teams to build scalable pipelines for knowledge graph population, enrichment, and lifecycle management. * Develop strong client relationships and earn the trust of key stakeholders as a strategic advisor. * Communicate complex ontological concepts and graph architectures clearly to both technical and non-technical audiences. * Evaluate and pilot emerging tools, frameworks, and standards (e.g., LPG vs. RDF, Wikidata, schema.org, W3C standards). ## Related Videos - [How a Small Team Shrank a Microsoft Monorepo by 94%](https://www.wearedevelopers.com/videos/1236-how-a-small-team-shrank-a-microsoft-monorepo-by-94) - [Putting the Graph In GraphQL With The Neo4j GraphQL Library](https://www.wearedevelopers.com/videos/257-putting-the-graph-in-graphql-with-the-neo4j-graphql-library) - [New AI-Centric SDLC: Rethinking Software Development with Knowledge Graphs](https://www.wearedevelopers.com/videos/1417-new-ai-centric-sdlc-rethinking-software-development-with-knowledge-graphs) - [Knowledge graph based chatbot](https://www.wearedevelopers.com/videos/754-knowledge-graph-based-chatbot) - [Graphs and RAGs Everywhere...
