This role collaborates with solution architects, product owners, program managers, business analysts, infrastructure teams, and service providers to deliver data and analytics solutions.

Responsibilities

Graph data modeling. Contribute to Design and refine labeled-property and/or RDF graph models — nodes, relationships, properties, and constraints — that accurately represent entities and their connections across source systems.
Pipeline development. Build, test, and maintain ingestion pipelines that extract data from relational, document, and file-based sources, transform it, and load it into the graph using batch and incremental patterns.
Query engineering. Write, optimize, and document Cypher queries for data loading, validation, entity resolution, and downstream retrieval, including support for graph-backed and retrieval-augmented applications.
Data quality and validation. Implement constraints, validation rules, entity resolution (e.g., SHACL or property checks), and automated tests that keep the graph consistent, traceable, and trustworthy.
Performance and operations. Monitor graph performance, tune indexes and queries, and assist with environment management across development, validation, and production tiers.
Collaboration and documentation. Partner with cross functional teams, analysts, and domain subject-matter experts to gather requirements; document data models, lineage, and design decisions clearly for technical and non-technical audiences.

Required

Bachelor’s Degree with 2 years’ experience; or Master’s Degree equivalent education with no additional experience.

Exposure working with entity resolution, record linkage, knowledge graph construction, vector databases and embeddings, and retrieval-augmented generation (RAG) or graph-RAG patterns is preferred.
