  • Collaboration & Continuous Improvement

    • Participate in code reviews and contribute to coding standards, best practices, and documentation.

    • Stay informed of backend development trends and introduce relevant improvements to our technology stack.

    • Support onboarding and mentoring of new team members as we grow.

What We’re Looking For

  • Strong Technical Background

    • Proficiency in one or more backend languages: Python, Node.js, Typescript or Java

    • Solid understanding of API design and implementation (REST, GraphQL).

    • Hands-on experience with relational and NoSQL databases such as PostgreSQL, MongoDB, DynamoDB, or Redis.

  • Cloud & Infrastructure Experience

    • Familiarity with cloud environments (AWS, GCP, Azure).

    • Experience deploying and managing containerized applications (Docker, Kubernetes).

    • Understanding of infrastructure as code (Terraform, CloudFormation).

  • Software Best Practices

    • Experience with software testing methodologies (unit, integration, end-to-end testing).

    • Commitment to writing clean, maintainable, well-documented code.

  • Problem-solving & Communication

    • Excellent problem-solving skills with the ability to debug complex systems.

    • Strong collaboration skills, capable of working effectively across teams and clearly communicating technical concepts.

  • Growth Mindset

    • Passion for continuous learning and staying current with the latest advancements in backend engineering, distributed systems, and cloud infrastructure, as well as a commitment to mentoring and teaching others.

Bonus Points

  • Experience with building and integrating on Palantir Foundry and its various offerings

  • Knowledge of defense or logistics industries and legacy system modernization.

  • Contributions to open-source software or active engagement with the developer community.

Why Gallatin?

  • Join a mission-driven, high-impact, and fast-moving startup where your work directly improves defense logistics readiness for the warfighters of the United States and allied forces.

  • Work alongside a team of passionate engineers, designers, and industry experts.

  • Competitive compensation incl. generous options grant, 100% employer-paid health insurance premiums, 401k, opportunities for rapid career growth, unlimited PTO, free lunches and snacks in the office.

This position requires the ability to obtain and maintain relevant security clearances. The successful candidate must be able to work in a classified environment when necessary.

If you’re not excited about working hard, and solving the hard problems of building AI decisions-support systems that enhance our warfighters, don’t apply.
