Forward Deployed Engineer

Braintrust is building the modern platform for evaluating and deploying AI systems. Our mission is to help enterprises build trust in their AI by making it easy to test, monitor, and improve models using real-world evaluation frameworks. We work with cutting-edge customers in finance, healthcare, and tech who are building production-grade AI systems.

As a Forward Deployed Engineer (FDE) on our Professional Services team, you'll work directly with customers to get them up and running with Braintrust’s platform. You’ll lead hands-on technical engagements, helping teams define, build, and operationalize AI evaluation frameworks that reflect their real-world goals.

This is a hybrid role that blends software engineering, customer collaboration, and delivery excellence. You’ll partner closely with customer ML, data, and engineering teams to implement evaluation pipelines, define metrics, and build custom logic that plugs into Braintrust’s platform.

You’ll also act as a feedback loop for our product and engineering teams, helping shape the future of the platform based on what you see in the field.
