About the role

Remote position, with preference for the Washington DC metro area. Requires an active Secret security clearance (interim OK), US citizenship, and 0‑10% travel. The Department of War is fielding AI‑enabled decision support at unprecedented speed, and Maven Smart System is at the center. Sherpa 6 builds mission‑critical software that puts operational data in the hands of users from the Pentagon to the tactical edge, running on 100,000+ fielded endpoints. As a Full Stack Foundry Engineer you will own a greenfield application that works alongside the Maven Smart System ecosystem backed by Palantir’s Foundry, shaping architecture from your first commit, with weekly releases and direct user feedback.

Responsibilities

• Own technical direction, estimation, and on‑time feature delivery.
• Implement scalable, secure, and observable system architectures (APIs, services, data models, caching, integrations).

• Model schemas via Ontology to ensure optimal querying and performance speed.
• Code and test software based on loose customer requirements and minimal user interface designs.
• Apply sound software engineering principles to ensure code is modifiable, efficient, reliable, understandable, and fault tolerant.

Requirements

• Active Secret security clearance (interim OK).
• Prior hands‑on Palantir Foundry development experience — built applications, data pipelines, or ontology‑backed workflows in Foundry (Ontology design, Workshop/Slate apps, Foundry Functions (TypeScript), ideally Ontology SDK (OSDK) for custom React apps).
