Sr Palantir Foundry Data Engineer

Senior Palantir Foundry Data Engineer who knows how to build under the hood. This isn't a front-end dashboard or basic analyst role. We need a true builder responsible for core infrastructure, pipeline development, and complex ontology mapping who has spent serious time managing tight data governance boundaries and enterprise-scale solutions. Daily, you'll handle the real plumbing of the platform. Requirement: We need someone who confidently uses Ontology Manager and Pipeline Builder to architect data models, configure Join Objects for many-to-many relationships, and write production-grade PySpark, SQL, and Python inside Foundry repositories. You'll also deploy solutions using AIP Logic and AIP Agents, ensuring safe writeback capabilities to ontology objects through Action Types while managing sandboxed environments and tricky third-party library dependencies. Because we need a real engineer, our technical vetting process is rigorous and highly focused on execution mechanics. We want to hear about your actual production projects-the edge cases you ran into, the environment limitations you overcame, and your architectural choices. Deep mastery of the Foundry ecosystem (Workshop, Contour, Automate) is a must. If you can talk through the plumbing of your past projects with fluidity and confidence. Saxon Global
