## About the role

We’re hiring engineers to build the open-source libraries that customers use to observe, understand, and optimize how AI operates inside their production applications. These SDKs are a critical part of Braintrust’s platform. They power evaluation and observability pipelines across a wide range of environments, frameworks, and AI providers.

## What they're looking for

- Are customer-obsessed and passionate about solving real-world problems for developers
- Have deep expertise in Go and understand what it takes to build fast, idiomatic, and reliable libraries in that ecosystem
- Are proficient with the tooling needed to build robust SDKs, such as testing frameworks, profilers, CI/CD pipelines, and packaging systems
- Care deeply about developer experience, from clean APIs and clear docs to thoughtful error handling and backward compatibility
- Know how to wrap, patch, or extend existing frameworks and SDKs to inject observability and control without breaking developer workflows
- Have experience maintaining or contributing to production-grade open-source libraries, ideally used across multiple environments
