Software Engineer with Clearance (TS, TS/CSI)

About Gallatin

At Gallatin, we are rebuilding logistics infrastructure for the national security missions of the United States and allied partners. We build AI systems that determine how logistics decisions are made — not just how they're executed. From factory to foxhole, we operate at the layer where data becomes decisions, and decisions make the advantage.

About the Role

We are looking for cleared (TS or TS/SCI required) engineers who can build demo-able end-to-end flows that make resupply operations smarter, faster, and more resilient. You'll collaborate daily with a top notch team of engineers who value thoughtful design and practical impact. If you’re looking to build systems that go beyond the usual SaaS cloud-based product, this could be your next chapter.

Mission and Identity

We are building the system that enables faster, smarter logistics decisions in contested environments, and we're doing it with a team of seasoned entrepreneurs, operators, and technologists who have built and scaled solutions in this space before. We hold ourselves to an extremely high standard. We value clear thinking, direct communication, and the kind of ownership that doesn't stop until something actually works.

Our mission is to create decision advantage when the stakes are the highest. If we succeed, the system doesn't just run; it gets smarter. We're not building AI for its own sake. We're building it because faster, smarter decisions in the most demanding environments on earth can't wait. If you want to work somewhere the stakes are real and the mission is urgent — you'll fit in here.
