Job Description:
We are seeking an experienced Data Architect with deep expertise in Knowledge Graphs, Semantic Modeling, Graph Databases, and AI/LLM-driven Data Architectures. The ideal candidate will be responsible for designing and implementing enterprise-scale semantic data platforms that enable intelligent data discovery, contextual insights, and AI-powered decision-making.
This role requires strong experience in building knowledge graphs, semantic layers, ontology frameworks, graph databases, and Model Context Protocol (MCP) services to support next-generation AI and data products.
Key Responsibilities
- Design and implement enterprise-scale Knowledge Graph and Context Graph architectures to model complex business domains and relationships.
- Develop and maintain entity resolution frameworks, relationship modeling strategies, and graph traversal patterns.
- Architect and govern enterprise Semantic Layers, including business-to-technical mappings, metric definitions, and governed data access models.
- Lead the design and implementation of Semantic Models, ontologies, taxonomies, and domain-driven schemas aligned with business capabilities.
- Build and optimize Graph Database solutions using platforms such as Neptune, Neo4j, or equivalent graph technologies.
- Design hybrid Graph + Vector Retrieval architectures to support AI/ML and Retrieval-Augmented Generation (RAG) use cases.
- Develop and maintain Model Context Protocol (MCP) Servers and context retrieval services to enable seamless tool integration for LLM-powered applications.
- Collaborate with business stakeholders, enterprise architects, data engineers, and AI teams to define semantic standards and governance frameworks.
- Establish best practices for metadata management, data lineage, semantic governance, and knowledge representation.
- Optimize graph queries, retrieval performance, and scalability across large enterprise datasets.
- Support AI and Generative AI initiatives by providing contextual data architectures that improve model grounding and response quality.
- Create architecture documentation, design standards, and implementation roadmaps for semantic and graph-based solutions.
Required Qualifications
- Bachelor’s or Master’s degree in computer science, Information Systems, Data Engineering, or a related field.

- Expertise in:
- Entity Resolution
- Relationship Modeling
- Graph Traversal Techniques
- Knowledge Representation
- Deep understanding of Semantic Layer Architecture and governed data access patterns.
- Experience designing and implementing Semantic Models, Ontologies, and Domain Schemas.
- Hands-on experience with Neo4j, Amazon Neptune, TigerGraph, or similar graph database platforms.
- Experience with graph query languages such as: Cypher, Gremlin, SPARQL
- Knowledge of Vector Databases and hybrid Graph + Vector retrieval architectures.
- Experience building APIs, context retrieval services, and Model Context Protocol (MCP) integrations for AI applications.
- Strong understanding of metadata management, data governance, and enterprise architecture principles.
- Experience working with cloud platforms such as AWS, Azure, or Google Cloud Platform.
Preferred Qualifications
- Experience supporting Generative AI, RAG, Agentic AI, and LLM-based applications.
- Familiarity with Business Capability Modeling (BCM) and capability mapping frameworks.
- Knowledge of semantic web technologies, RDF, OWL, and linked data concepts.
- Experience with AI orchestration frameworks such as LangChain, LangGraph, Semantic Kernel, or similar platforms.
- Experience integrating graph databases with data lakes, warehouses, and enterprise data platforms.
- Relevant certifications in cloud architecture, data architecture, or graph technologies.
