Palantir Foundry Developer / Data Engineer

About the Role

We're hiring a Palantir Foundry Developer / Data Engineer for a contract engagement, fully remote within the United States. You'll own the platform end-to-end: designing ontologies, building pipelines, and delivering user-facing applications.

What You'll Do

• Own end-to-end Foundry pipeline development: data ingestion, Code Repository transforms (PySpark/Python/SQL), dataset structuring, and incremental processing logic.
• Design Foundry Ontologies: define object types, link types, properties, action types, and functions that accurately model the business domain.
• Build Workshop applications: configure object tables, filters, action forms, map views, and writeback workflows for business users.
• Integrate AIP (Palantir's LLM layer): build agents, LLM-backed actions, and natural language interfaces on top of Ontology objects.
• Implement Foundry Expectations and data quality checks embedded directly in pipeline logic.
• Support OSDK-based custom application development where required.
• Partner with stakeholders to translate business requirements into Foundry data models and applications.

What We're Looking For

• Production Palantir Foundry experience, ideally at an enterprise customer or through a Palantir-contracted engagement
• Hands-on experience with Foundry Code Repositories (PySpark transforms, incremental pipelines, schema management)
• Familiarity with Foundry Ontology Manager: object types, link types, action types, functions, and access scoping
• Experience building Workshop applications: widgets, object tables, action forms, map/detail views
• Palantir AIP experience (LLM integration, agents, natural language actions) is a strong plus

Nice to Have

• Experience with Foundry Expectations, schema drift detection, and data validation frameworks
• OSDK (Ontology SDK) usage for custom React or frontend application development
• Experience with Foundry Media Sets and RAG pipeline implementation
• Quiver, Contour, or Slate experience for advanced analytics and visualization within Foundry

Engagement Details

• Contract (W2, 1099, or C2C) · Fully remote within the United States · US work authorization required · No sponsorship available.
• Nashville, TN area candidates given first preference for potential onsite requirements.
