  • Publish graph‑derived datasets to Snowflake, Power BI, and DataZone
  • Productionize reusable graph query packs for analytics and data consumers
  • Implement ontology/schema design, identity resolution, and relationship modeling
  • Work with batch/streaming ETL pipelines using Python, Spark/Lightning, APIs, and structured formats (JSON/CSV/Parquet)
  • Ensure performance, observability, and monitoring for graph workloads
  • Package datasets for secure consumption with proper AuthN/Z and row/column‑level controls
  • Collaborate with engineering, data, and platform teams to integrate graph systems into enterprise workflows

Requirements:

  • Graph Technologies: Strong hands‑on experience with RDF/OWL/SPARQL or Property Graph (Neo4j/TinkerPop) ecosystems
  • Proficiency with Cypher, Gremlin, and graph databases like GraphDB, Fuseki, Neptune, Neo4j
  • Modeling & Semantics: Expertise in ontology design, schema modeling, SHACL/SHEX constraints, and identity resolution
  • Strong understanding of relationship modeling and semantic structures
  • Data Engineering: Python programming
  • Spark/Lightning ETL
  • REST APIs
  • Experience working with JSON, CSV, Parquet, and CI/CD pipelines
  • Experience with batch and streaming data ingestion
  • Performance & Operations: Hands-on experience in query tuning, indexing, caching, and observability/monitoring
  • Understanding of enterprise‑grade deployments and optimization workflows
  • Integration: Ability to publish graph slices to Snowflake, and prepare datasets for DataZone including row/column‑level security
  • Work Experience Min: 4
  • Work Experience Max: 8

Nice to have:

  • Experience with reasoners such as HermiT or ELK
