Software Engineer, SDK
Braintrust, Remote +2
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.
This role is ideal for engineers who are passionate about developer experience, API craftsmanship, and building fast, reliable, and idiomatic libraries. You’ll own the full SDK lifecycle: design, implementation, release, documentation, and community support. Your work will be embedded in thousands of applications and help define how AI is adopted and operationalized across industries.
What you will do
- Build elegant, idiomatic, and resilient SDKs that power Braintrust’s LLM evaluation and AI observability platform.
- Ensure our libraries are easy to use, efficient to run, and a delight to work with, prioritizing developer experience and performance.
