Your work profile

Deloitte is looking for a Data Engineer with strong expertise in Knowledge Graphs, with GraphDB (RDF/OWL/SPARQL) as the preferred primary skillset, and Neo4j/Cypher as an alternative.
You will design and operate graph‑centric data architectures and integrate them with Snowflake to deliver high‑quality, governed, and semantically rich data products across the organization.

Key Skills & Competencies

• Knowledge Graph Engineering (Primary Focus)
• Design, build, and maintain RDF/OWL‑based knowledge graphs using GraphDB or similar triple stores.
• Develop ontologies, vocabulary, and semantic schemas to accurately represent business domains.
• Write and optimize SPARQL queries and implement reasoning/inference rules as needed.
• Manage ingestion pipelines to populate and update RDF graphs, ensuring consistency and performance.
• Support property graph modeling as secondary expertise using Neo4j/Cypher where applicable.
• Build and maintain curated Snowflake data products: domain‑aligned tables, views, and semantic layers.
• Implement ELT with Snowpipe, Streams, and Tasks, plus performance optimization and governance controls.
• Ensure strong documentation, data quality, lineage, and versioning for all Snowflake datasets.
• Develop and manage EL/ETL/ELT pipelines that feed both the knowledge graph and Snowflake.
• Use orchestration tools such as Airflow, Prefect, or Azure Data Factory for automation.
• Implement CI/CD for data workflows, with monitoring, alerting, and high‑reliability operational practices.
• Apply RBAC, masking, and row/column‑level security in both Snowflake and graph systems.
• Maintain lineage, metadata, and standardized documentation across all data assets.
• Define schema standards, semantic conventions, and data contracts with producers and consumers.
• Partner with domain experts, analysts, engineers, and ML teams to understand semantics and translate concepts into graph structures and data products.
• Advocate for graph‑driven design and semantic consistency across domains.
• Experience designing ontologies or complex semantic data models.
• Familiarity with dbt or other ELT frameworks.
• Exposure to Spark/Databricks.
• Experience with lineage/metadata tools (OpenLineage, Purview, Collibra).
• Experience building REST or GraphQL APIs for data access.

Preferred Qualifications

• Education - B. tech / BE in Computer Science or Information Technology.

Success Metrics

• 4–6 years of hands‑on data engineering experience.
• Strong, practical experience with GraphDB or any RDF/OWL/SPARQL‑based knowledge graph stack.
• Experience with Neo4j/Cypher as secondary graph expertise.
• Strong Snowflake ELT skills, including Snowpipe/Streams/Tasks and warehouse optimization.
• Proficiency in SQL and Python.
• Experience with structured and semi‑structured data (JSON, Parquet, Avro).
• Cloud object storage (S3/ADLS/GCS) experience.
• Hands‑on experience with Airflow/Prefect/ADF and Git‑based workflows.
