Palantir Field Engineer

Job Description

Job Description

Revolutional delivers advanced technology solutions and mission support to federal agencies across civilian, health, and national security environments. We apply modern capabilities, including AI/ML, cloud, cybersecurity, and IT modernization to solve complex challenges, enable faster and more secure operations, and drive measurable mission outcomes.

We are redefining how federal technology gets built and delivered by operating with a product mindset, prioritizing speed, ownership, and execution over bureaucracy.

Palantir Field Engineer (Systems Modernization)

Location: McLean, VA (Hybrid)

Terms: Full-time

Salary: $150-$185k DOE

Clearance: Ability to obtain and maintain a Public Trust required; Active DHS Public Trust preferred

Travel: 0–10%

About the Role

Revolutional is modernizing DHS's legacy mission systems onto Palantir Foundry. As the Palantir Field Engineer, you'll own the build-out of Foundry ontologies, pipelines, and Workshop applications that replace legacy functionality — working with incomplete documentation and deriving requirements from real system behavior rather than formal specs. This is a build-and-own role with a defined growth path to Lead Engineer / Platform Architect.

Responsibilities

• Engage directly with mission customers and end users to understand how they currently operate and where legacy systems help or hinder their workflows
• Translate mission needs into concrete technical requirements, ensuring ontology, pipeline, and application design stay grounded in how the platform will actually be used
• Design, build, and maintain Foundry ontologies, pipelines, and applications supporting DHS modernization
• Translate legacy system behavior into ontology objects, links, and actions
• Build data integration pipelines (batch and streaming) from legacy systems into Foundry, ensuring data quality, lineage, and security
• Develop Workshop or code workbook applications delivering modernized functionality to end users
• Own the full SDLC within Foundry: build, test, deploy, troubleshoot across pipeline, ontology, and application layers
• Partner with Full Stack Engineers and Systems Analysts to ensure legacy functionality is accurately represented
• Apply Foundry security and access-control patterns appropriate to a federal law enforcement data environment
• Participate in design reviews; mentor engineers through the Palantir certification path

What You Bring (Requirements)

• Bachelor's degree in CS or related field (or equivalent experience)
• 5+ years hands-on software engineering experience, including hands-on Palantir Foundry experience
• Deep hands-on experience in at least one Foundry layer (ontology, pipeline/code repositories, or Workshop), with working fluency across the others
• Strong Python skills, including PySpark for pipeline development
• Experience integrating data from relational databases and legacy systems
• Understanding of data lineage, access control, and security patterns within Foundry
• Strong systems thinking; ability to distinguish essential functionality from legacy process bloat
• Comfort working in ambiguous, poorly documented environments
• Ability to obtain and maintain required clearance

Nice to Have

• Palantir Foundry certification(s)
• Experience with legacy system modernization efforts
• Experience supporting federal or mission-driven environments, particularly DHS
• Hands-on build experience across all three Foundry layers: ontology, pipelines, and Workshop

Technical Environment

Palantir Foundry (ontology, pipeline builder, code workbooks, Workshop) · Python, PySpark, SQL · relational and legacy data systems, batch/streaming integration · Agile delivery, CI/CD, data governance and access control.
