Frontend Engineer

About Gallatin

At Gallatin, we are rebuilding defense logistics for the warfighters of the United States and allied forces. We take an AI-first approach to improve defense readiness through software products that streamline and modernize logistics operations from factory to foxhole and result in better decisions and outcomes.

We believe that you won’t change the world by phoning it in and as such we work from our office in El Segundo, California.

About the Role

You thrive at the intersection of clean UI execution and real-world impact. As a Frontend Software Engineer, you craft self-contained, reusable, task-focused components, and approach UI development with a balance of speed, quality, and empathy for the end user. While your focus is on the front end, your grasp of the entire stack is strong enough to contribute ideas, spot architectural tradeoffs, and help shape how our Navigator platform is designed end to end. You care deeply about Developer Experience, have a strong command of RESTful APIs and testing frameworks, and bring a strong sense of agency to improving code, tooling, and documentation.
