Responsibilities include building production-grade pipelines, integrating RDF/OWL, Neo4j, and Microsoft data services, and ensuring data quality and performance in the Azure stack.

Qualifications

• 8+ years of experience in data engineering, with a strong foundation in building production-grade data pipelines.
• Hands-on experience with the Microsoft Azure data stack — Azure Databricks, Azure Synapse Analytics, and/or Azure Data Factory in production environments.
• Hands-on experience with Databricks for data processing, transformation, and analytics workloads.
• Experience implementing data governance and cataloging using Unity Catalog.
• Practical experience with RDF and OWL for knowledge representation and ontology development.
• Hands-on experience with Neo4j or other graph database technologies.
• Experience designing semantic models and understanding of graph theory concepts.
• Proficiency in diagramming and process mapping tools such as Visio and Miro.
• Strong SQL skills and experience with Python or Scala for data engineering tasks.
• Solid understanding of data modeling principles (relational, dimensional, and graph-based).
• Strong analytical and problem-solving skills, with the ability to translate complex data relationships into clear architectural designs.
• Excellent communication skills, with the ability to work across technical and business teams.

Responsibilities

• Design, build, and maintain scalable data pipelines and lakehouse architectures using Azure Databricks.
• Implement and manage data governance, access control, and lineage using Unity Catalog, aligned with Microsoft Purview.
• Design and develop semantic data models to represent complex business domains and relationships.
• Build and maintain knowledge graphs using RDF (Resource Description Framework) and OWL (Web Ontology Language) standards.
• Design and implement graph database solutions using Neo4j to support relationship-driven data use cases, deployed on Azure infrastructure.
• Develop ontologies and taxonomies to enable consistent data interpretation across systems.
• Translate business processes and data relationships into architecture diagrams using Visio and Miro.
• Collaborate with data architects, analysts, and business stakeholders to align data models with organizational needs across the Microsoft data ecosystem (Azure Synapse, Microsoft Fabric).
• Optimize data pipelines for performance, reliability, and scalability using Azure Data Factory and Databricks Workflows.
• Ensure data quality, consistency, and integrity across ingestion, transformation, and storage layers, including Azure Data Lake Storage (ADLS Gen2) and Delta Lake.
• Support integration of semantic and graph-based data models with downstream analytics and AI/ML applications, including Azure OpenAI Service and Azure AI Studio where applicable.
• Document data architecture, pipelines, and semantic models for cross-team visibility and maintainability.
