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 Type Script, 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.

• Develop, enhance, run and maintain operational applications in Palantir Foundry.
• Build and support application components using Type Script, 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.

• 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.

• 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.

• 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.

• 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.

• 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 Type Script, 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…
