Full Stack Software Engineer- Foundry

Job Location: Remote, Washington DC metro area preferred

Security Clearance: Active Secret clearance required (interim OK)

Travel Requirement: 0-10%

Citizenship: US Citizenship Required

The Department of War is fielding AI-enabled decision support at a speed the defense industry has never seen — and Maven Smart System is at the center of it. Sherpa 6 builds mission-critical software that puts operational data in the hands of the people who need it, from the Pentagon to the tactical edge. Our systems already run on 100,000+ fielded endpoints across the Joint Force.

We're hiring a Full Stack Foundry Engineer to own a greenfield application that works alongside the Maven Smart System ecosystem backed by Palantir’s Foundry— built for senior DoW leaders who use it to make real decisions. You'll shape the architecture from your very first commit. No legacy codebase. No layers of program bureaucracy between you and the user. Your users are actively using the tool and providing feedback. Flash to bang is quick with weekly releases.

Your Foundry experience is the job, not a bonus. The application lives on Maven Smart System, so the ontology, Workshop, Functions, and OSDK skills you've built — at Palantir, a delivery partner, or a government program — are exactly what this role runs on every day. That expertise is rare, and here it's the centerpiece. Specific knowledge in using the DevOps Marketplace functionality to export and import applications, create and manage datasets, materialized datasets, and user edits all play an extremely critical part of this role. This expertise is required.

Responsibilities:

• Own technical direction, estimation, and on-time feature delivery.
• Implement scalable, secure, and observable system architectures (APIs, services, data models, caching, integrations).
• Build high-quality front-end experiences in React, and robust back-end services in Foundry using Ontology, Functions, and Datasets
• Model schemas via Ontology to ensure optimal querying and performance speed
• Code and test software based upon loose customer requirements and minimal user interface designs.
• Use sound software engineering principles to ensure that developed code is modifiable, efficient, reliable, understandable, and fault tolerant.

• Active Secret security clearance (interim OK)
• Prior hands-on Palantir Foundry development experience — this is a critical qualification. You've built applications, data pipelines, or ontology-backed workflows in Foundry: Ontology design (object types, links, actions), Workshop and/or Slate applications, Foundry Functions (TypeScript), and ideally the Ontology SDK (OSDK) for custom React apps.
• Experience with Maven Smart System, AIP, or Gotham in a defense or intelligence context strongly preferred.
• 6–10+ years of professional software engineering
• BS degree in Software Engineering, Computer Science, or related field.
• Demonstrated experience with asynchronous programming, observables, and data structuring.
• Node.js/TypeScript building REST APIs and solid understanding of concurrency, async patterns, and API design.
• Demonstrated experience with application state management strategies.
• Solid understanding of HTML and CSS, including responsive design principles, CSS preprocessors, and knowledge of UI frameworks.
• Developing full stack web applications following design team specifications.
• Familiarity with front and backend build tools and package managers.
• Strong team player who thrives in a highly collaborative and cross-function environment, with a growth mindset.
• Development processes: source control, defect tracking, and collaborative tools; code review a plus.
