• At least 2 years of hands-on experience developing graph-based applications, knowledge graphs, or graph data platforms.
• Advanced proficiency in Python and libraries such as NetworkX, Pandas, NumPy, or similar.
• Strong understanding of graph data modeling, graph traversal, indexing, and query optimization.
• Hands-on experience with a graph database such as Neo4j, Amazon Neptune, or Azure Cosmos DB for Apache Gremlin.
• Proficiency in a graph query language such as Cypher, Gremlin, or SPARQL, and understanding of property graph or RDF models.
• Experience building data ingestion and transformation pipelines across structured and unstructured sources.
• Familiarity with entity resolution, ontology design, data lineage, and graph data quality practices.
• Excellent communication skills, including explaining graph concepts and technical tradeoffs to nontechnical stakeholders.
• Strong analytical and problem-solving skills, with attention to data quality and system reliability.
• Ability to own projects from design through deployment and collaborate across disciplines.
• Comfort navigating ambiguity and evolving priorities in a fast-paced startup.
• Bachelor’s or Master’s degree in Computer Science, Engineering, or a related field, or equivalent practical experience.

Nice To Haves

• Experience using knowledge graphs in AI or agentic applications to support graph or hybrid Graph-RAG retrieval.
• Familiarity with knowledge graphs in AI applications, including GraphRAG, hybrid graph and vector retrieval, or agent tools.

Responsibilities

• Design and build scalable knowledge graphs, defining schemas, ontologies, entities, and relationships that reflect complex business domains.
• Build pipelines to extract, normalize, and connect data from documents, databases, and external systems, including support for incremental updates.
• Implement entity matching, deduplication, relationship validation, and provenance tracking to maintain trustworthy graph data.
• Develop graph-based retrieval capabilities and integrate them with vector search, RAG systems, and AI agents.
• Optimize graph queries, indexing, and storage; implement testing, monitoring, access controls, and recovery practices.
• Develop production-grade Python services, APIs, and pipelines for graph ingestion, querying, and integration with enterprise applications.

Benefits

• Competitive compensation tailored to experience and skill set.
• Flexible work arrangements with a hybrid working model.
• Opportunities for professional development and technical leadership.
• Opportunity to build technologies that connect enterprise knowledge and power the next generation of AI applications.
