By connecting evals and observability in one workflow, Braintrust gives builders the visibility to understand how AI behaves in production and the tools to improve it. Teams at Notion, Stripe, Zapier, Vercel, and Ramp use Braintrust to compare models, test prompts, and catch regressions — turning production data into better AI with every release.\r\nAbout The Role\r\nWe'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.\r\nWhat You'll Do\r\nBuild elegant, idiomatic, and resilient SDKs that power Braintrust's LLM evaluation and AI observability platform.\r\nEnsure our libraries are easy to use, efficient to run, and a delight to work with, prioritizing developer experience and performance.\r\nIntegrate with major AI providers, frameworks, and platforms our customers rely on, such as OpenAI, Anthropic, and Gemini.\r\nBuild tools and automation to improve testing, profiling and simplify release workflows.\r\nCollaborate closely with backend, platform, and product teams to ensure a cohesive and polished developer experience.\r\nBe a great community ambassador: talk with our users, understand their issues, help them get their fixes merged and have deep empathy for our users.\r\nYou Might Be a Fit If You\r\nAre customer-obsessed and passionate about solving real-world problems for developers.\r\nHave deep expertise in Python and understand what it takes to build fast, idiomatic, and reliable libraries in that ecosystem.\r\nAre proficient with the tooling needed to build robust SDKs, such as testing frameworks, profilers, CI/CD pipelines, and packaging systems.\r\nCare deeply about developer experience, from clean APIs and clear docs to thoughtful error handling and backward compatibility.\r\nKnow how to wrap, patch, or extend existing frameworks and SDKs to inject observability and control without breaking developer workflows.\r\nHave experience maintaining or contributing to production-grade open-source libraries, ideally used across multiple environments.\r\nBonus: You've contributed to popular open-source projects, led SDK adoption at your organization, are familiar with tracing and observability tools like OpenTelemetry, or worked on tools in the LLM/AI ecosystem.\r\nBenefits include\r\nMedical, dental, and vision insurance\r\nDaily lunch, snacks, and beverages\r\nFlexible time off\r\nCompetitive salary and equity\r\nAI Stipend\r\nEqual opportunity\r\nBraintrust is an equal opportunity employer.
