About The Position
Seeking a senior engineer to embed with Marine Corps Systems Command and build AI-enabled data applications on the Marine Corps' Palantir Foundry environment, part of the War Data Platform. This is a hands-on build role embedded with the customer. The first six months are about getting the data architecture right and shipping working software, not producing roadmaps for someone else to execute.
Requirements
- Active Secret clearance.
- Hands-on production Palantir Foundry experience: Pipeline Builder, code repositories, transforms, and ontology development
- Strong application development ability in TypeScript, React, and Python
- Real experience integrating external APIs and moving data between enterprise systems
- You have shipped an AI or LLM-backed feature to actual users and handled it being wrong in production
- Comfort with ambiguity. You've walked into a project where the customer couldn't articulate what they wanted and returned with a scope
- Ability to hold your own in a room with senior government leadership
Nice To Haves
- Foundry application layer: Ontology SDK, Workshop, AIP
- Microsoft Graph API and SharePoint Online integration
- Databricks, Spark, or lakehouse architecture experience
- Prior work with the War Data Platform, Advana, or comparable DoD enterprise data platforms
- Federated or distributed data architecture design
- IAT Level II (Security+). If you don't have it, we'll pay for it.
- Marine Corps, Navy, or DoD modernization experience
Responsibilities
- Partner directly with the customer's CIO staff to scope an AI capability for meeting minutes and schedule management, starting from an idea rather than a requirements document
- Design the underlying data architecture and models before anything gets built on top of them
- Integrate Microsoft SharePoint and other authoritative sources into Foundry using the Microsoft Graph API, including app registration, permissions, and sync
- Build production pipelines and transforms in Foundry, and develop the ontology objects the applications depend on
- Build and ship working applications in Foundry using TypeScript, React, and Python
- Collaborate with Palantir engineering on repository and data access setup
- Demo working software to senior government stakeholders and iterate on what you hear
- Advise government leadership on data architecture, interoperability, and how the environment should scale
Benefits
- Paid Vacation, Sick Time and Holidays
- Medical, Dental, Life and Disability Insurance
- 401K with Employer Contribution Matching
