Staff Engineer - Data Modeler

Nagarro is a digital product engineering company that builds products, services, and experiences across digital mediums worldwide. The Staff Engineer - Data Modeler will design and govern data architecture for unstructured knowledge assets, define data products and metadata standards, and manage secure cataloging in Databricks Unity Catalog. The role partners with engineering, knowledge, research, architecture, privacy, and legal stakeholders to support scalable knowledge management and retrieval systems.

Responsibilities:

• Design logical and physical data models for unstructured and semi-structured content (documents, case artifacts, K-Slices, extracted knowledge fragments, metadata records) originating from KM pipelines such as case mining and informal knowledge capture workflows
• Define domain boundaries and ownership for data products — determining what constitutes a discrete, reusable data product versus a raw or intermediate asset
• Establish metadata standards and tagging taxonomies (content type, practice/domain, provenance, confidentiality, freshness, lineage) to ensure consistent classification across knowledge sources
• Assign and enforce security and sensitivity classifications on data products in line with firm data governance, privacy, and legal/risk requirements
• Register, document, and maintain data products in Databricks Unity Catalog, including schemas, access grants, lineage, and catalog-level metadata
• Partner with data engineers building Databricks pipelines to ensure ingestion, transformation, and storage patterns align to the modeled domain structure
• Collaborate with Knowledge Products, Research Products, and Architecture/Data/Technology stakeholders to align data product design with downstream consumption needs (e.g., surfacing in Sage/Glean, AI agent retrieval)
• Support privacy and legal review processes by ensuring data products are classified and documented to enable timely sign-off
• Establish and document repeatable modeling standards/playbooks so future data products can be onboarded consistently as the KM platform scales

Requirements:

• Data Modeling (Strong), Databricks
• 5+ years of experience in data modeling, data architecture, or information architecture, with meaningful exposure to unstructured or semi-structured data (not purely relational/transactional modeling)
• Direct experience working in or adjacent to Knowledge Management, content management, or enterprise search domain — understands how documents, case files, or knowledge artifacts differ from standard transactional data
• Hands-on experience with a modern data catalog; Databricks Unity Catalog experience strongly preferred
• Demonstrated ability to define data domains and data product boundaries in a large, multi-stakeholder organization
• Practical knowledge of metadata management: tagging schemas, taxonomies, controlled vocabularies, or ontology design
• Understanding of data security/sensitivity classification frameworks and how they map to access control in a Lakehouse environment
• Experience partnering with data engineering teams on ingestion and pipeline design (not required to write production pipeline code, but must speak the language)
• Strong written and verbal communication skills; able to translate technical modeling decisions into business-readable rationale for KM stakeholders and governance reviewers
• BI Schema Design - General Experience
• Experience with enterprise knowledge platforms (e.g., Glean, SharePoint, ServiceNow) or AI-powered retrieval systems
• Familiarity with Databricks Delta Lake, Delta Sharing, or Lakehouse Federation
• Prior experience in professional services, consulting, or a similar document/case-intensive knowledge environment
• Exposure to Legal/Risk/Privacy review processes for data classification and access approvals
• Background in library science, information science, or applied ontology is a plus but not required
