Ontology Designer - Data42

Major accountabilities:

• Lead end-to-end Ontology design in Foundry, defining Object Types, Action Types, relationships, properties, and metrics aligned to business processes and outcomes.
• Translate domain workflows into an operational data model that supports both real-time decisioning and analytical use cases.
• Map upstream data sources and pipelines into the Ontology; establish semantic contracts and data contracts to ensure stability and evolvability.
• Foundry Application Development is a plus
• Configure governance: access controls, row/column-level permissions, lineage visibility, and certification to meet compliance and privacy requirements.
• Collaborate with data engineers to shape transforms and data quality checks that feed Ontology objects and actions.
• Partner with application builders to ensure Ontology supports operational apps, forms, and workflows (e.g., case/issue management, asset lifecycle, supply/finance/ops scenarios).
• Establish versioning, change-control, and deprecation strategies for Ontology elements; maintain documentation and data dictionary.
• Define and track Ontology KPIs (coverage, freshness, quality, adoption, performance) and drive continuous improvement.
• Conduct discovery sessions with stakeholders; facilitate design workshops; provide enablement and best practices across teams.
• Troubleshoot modeling issues, performance bottlenecks, and access constraints; steward Ontology health across dev/test/prod environments.
• Collaborative, product-minded, and iterative approach to design and delivery.
• Comfortable working across strategy, architecture, hands-on configuration, and stakeholder enablement.

Minimum Requirements:

Work Experience:

• Bachelor's degree in Computer Science, Engineering, or related technical field; Master's degree preferred

• 4+ years in data modeling, enterprise data design, or knowledge/graph modeling, with at least 1–2 years working directly with Palantir Foundry Ontology (or equivalent Ontology-driven platforms).
• Strong grasp of conceptual/logical/physical modeling; object–action modeling; relationship/graph patterns; semantic consistency and naming conventions.
• Experience building or supporting Foundry operational applications and workflows using Ontology-driven patterns.
• Exposure to ML/AI integration in Foundry (feature exposure via Ontology, model inferences as objects/actions).
• Knowledge of cloud data ecosystems (AWS) and modern warehouses/lakes (e.g., Snowflake, Databricks).
• Familiarity with data quality frameworks, schema validation, and testing strategies in CI/CD contexts.
• Hands-on experience integrating heterogeneous data sources and pipelines into operational models; familiarity with SQL and at least one scripting language (e.g., Python).
• Practical understanding of data governance: RBAC, row/column-level security, PII handling, lineage, and compliance controls.
• Proven ability to translate business processes into scalable Ontology designs that support operational and analytical applications.
• Excellent communication and facilitation skills; ability to align diverse stakeholders and document complex systems clearly.
• Palantir certifications: Foundry Solution Architect, or Foundry Application Developer
