About the Role
We’re looking for an AI/ML Software Engineer to play a foundational role in building and deploying AI-powered solutions for our core product. You’ll work across the full AI/ML lifecycle, from defining and building models to evaluating and deploying large-scale ML pipelines and real-time inference systems, while partnering with cross-functional teams to deliver impactful, real-world AI applications.
What You’ll Do
•
Build and Deploy AI/ML Models
•
Own and develop an AI model aligned with our core product needs within your first three months.
•
Validate AI-driven product features through real-world testing and feedback from warfighters.
•
Establish scalable MLOps pipelines and real-time inference services to streamline model training, deployment, runtime, and monitoring.
•
Own high model reliability and uptime by implementing monitoring across your work.
•
Data Collection & Processing
•
Identify and integrate structured, unstructured, batch, and real-time data sources.
•
Work with internal logs, APIs, user interactions, and third-party datasets to improve training data quality.
•
Continuous Improvement & Best Practices
•
Stay ahead of emerging AI trends and technologies to improve model performance.
•
Document and share AI/ML development best practices.
•
Contribute to the hiring and mentoring of AI/ML talent as we grow our team.
•
Help the wider team understand the latest trends and the significance of novel approaches in AI.

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.
Why Gallatin?
The logistics infrastructure that supports America’s warfighters and humanitarian disaster responders is overdue for transformation, and we are building it. From defense operations to disaster response, we’re solving the hardest problems that keep missions moving when it matters most. Join a team where the mission is the point.
Compensation: Gallatin offers competitive compensation commensurate with experience. Actual compensation may vary based on experience, skills, and location. In addition to base salary, we offer a generous equity grant, full healthcare coverage, 401k, unlimited PTO, and the perks of working in a high-caliber, mission-driven environment.
