  • Implement security and governance through markings, restricted views, and mandatory controls.
  • Read, debug, and write Python and PySpark for data engineering workflows.
Required Qualifications
Experience: A minimum of 4 years of related technical experience is required. Experience will be considered in lieu of a college degree.
Technical Skills:
  • Must be able to obtain and maintain a secret clearance.
  • Experience with Palantir Foundry, Army Vantage, and Workshop development.

General Skills:
  • Must be able to obtain and maintain a secret clearance.
  • Strong written and verbal communication skills.
  • Strong collaboration skills and a desire to work within a team.
  • Ability to work in a fast-paced, constantly changing environment.
  • Experience working on a Scrumban team in an Agile environment.
Preferred Qualifications
  • TypeScript Functions and custom React widgets for Workshop.
  • OSDK application development outside of Workshop.
  • Palantir certifications (MCP, Data Engineer, or Application Developer track).
  • Experience with Palantir MAVEN or developing in Army 365 (A365).
  • Familiarity with the Azure Data/AI stack (Azure Databricks, Synapse, or Data Factory).
  • Experience developing with the Microsoft Power Platform suite.
