Data Engineer

We are looking for experienced Foundry Application & Data Engineers to support the run, maintenance and enhancement of operational applications on Palantir Foundry. The role involves a combination of application support, incident resolution, data ingestion, data processing, ontology development, writeback implementation, restricted views, and Foundry application development using TypeScript, React and OSDK. This is a hybrid role suited to someone who can work across both data engineering and application enablement within Palantir Foundry. The candidate does not need to be a pure front-end developer, but should be comfortable supporting and enhancing ontology-backed applications where the application logic is closely linked to data products, workflows and governed data access.

Key Responsibilities

• Foundry Application Development
  • Develop, enhance, run and maintain operational applications in Palantir Foundry.
  • Build and support application components using TypeScript, React and OSDK.
  • Configure and consume ontology objects, actions and functions within Foundry applications.
  • Support operational workflows involving users, governed data access and writeback.
  • Troubleshoot application issues, user-reported defects and operational incidents.
  • Work with product owners, service teams and users to understand application behaviour and support needs.
  • Ensure applications are maintainable, supportable and aligned with Foundry delivery standards.
• Ontology and Writeback
  • Build and maintain Foundry ontology objects, object types, links, actions and functions.
  • Configure ontology-backed workflows to support operational use cases.
  • Implement and support writeback patterns where users need to update, enrich or correct operational data.
  • Ensure writeback logic is governed, auditable and aligned with access controls.
  • Support restricted views and controlled data access patterns.
• Data Engineering and Processing
  • Build, maintain and support data ingestion and transformation pipelines in Foundry.
  • Develop data processing logic using Python, PySpark and Foundry Code Repositories.
  • Support ingestion from upstream sources and provisioning of curated datasets for downstream use.
  • Investigate data issues related to quality, completeness, latency, schema changes and failed jobs.
  • Maintain data lineage, transformation logic and operational documentation.
  • Support deployment and release of data engineering changes through Foundry development workflows.
• Incident Resolution and Live Service Support
  • Provide advanced support for operational applications and data products.
  • Investigate and resolve incidents across application, ontology, data pipeline and access layers.
  • Perform root cause analysis and recommend permanent fixes.
  • Support service continuity for business-critical applications.
  • Work with service management teams to triage, prioritise and resolve issues.
  • Maintain support runbooks, known error logs and operational knowledge articles.
  • Support controlled data provisioning requests.
• Workshops and Stakeholder Engagement
  • Participate in workshops with business, product, data and service teams.
  • Translate business requirements into Foundry data products, ontology design and application features.
  • Support discovery, solution design, impact assessment and delivery planning.
  • Explain technical options clearly to non-technical stakeholders.

Required Skills and Experience

• Strong hands-on experience with Palantir Foundry.
• Experience developing and supporting Foundry operational applications.
• Good understanding of Foundry Ontology, including objects, links, actions and writeback.
• Experience with Foundry Code Repositories.
• Experience with data ingestion, transformation and data processing pipelines.
• Working knowledge of TypeScript, React and OSDK.
• Understanding of governed data access, restricted views and role-based access patterns.
• Ability to troubleshoot production data and application issues.
• Experience working in incident resolution or live service support environments.
• Ability to work with business users, product owners, service architects and data teams.
• Good documentation skills, including runbooks, support notes and technical design documentation.
• Experience in healthcare, public sector or regulated data environments.
• Experience with Foundry Workshop applications.
• Experience with data provisioning services.
• Experience with access control, data governance and information governance processes.
• Experience with CI/CD or structured release processes in Foundry.
• Experience with production support, service transition and operational readiness.
• Familiarity with incident, problem and change management processes.
• Experience working with sensitive or restricted data in a governed platform environment.

The role will contribute to:

• Operational Foundry applications maintained and enhanced.
• Incidents triaged, investigated and resolved.
• Data ingestion and processing pipelines maintained.
• Ontology objects, actions and writeback patterns implemented or supported.
• Restricted views and governed access patterns maintained.
• Data provisioning requests fulfilled.
• Support runbooks and technical documentation updated.
• Root cause analysis and service improvement actions completed.
• Workshops supported with technical input and solution options.
