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.

  • API request testing experience with tools such as Postman or Insomnia

  • Troubleshoot CORS issues

Bonus Points

• Familiarity with legacy systems and working with public sector customers

• Comfortable setting up CI/CD pipelines and DevOps workflows

Why Gallatin?
