Jobs at Braintrust

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 large language models become core building blocks for modern software, product teams are realizing that traditional development tooling is not sufficient. Unlike deterministic systems, LLM-based applications are non-deterministic and sensitive to small changes in prompts, model versions, or inputs. Logging, evaluating, and improving these systems requires infrastructure purpose-built for AI behavior. Braintrust provides that infrastructure. It enables teams to instrument, serve, evaluate, and iterate on LLM-powered features with reproducibility, scale, and observability in mind.

Braintrust is already used by top AI-native product teams including Notion, Stripe, Zapier, Airtable, Instacart, Coda, and The Browser Company. What sets the platform apart is its depth of functionality: full-stack support for prompt templating, real-time serving, model proxying, structured trace logging, versioned datasets, and scoring infrastructure. Braintrust also includes its own purpose-built database, optimized for storing and querying complex, multi-turn traces. Its flexible interface supports both low-code experimentation and deep integration into production systems. Founder Ankur Goyal brings relevant experience from SingleStore, Impira, and Figma, and the team’s background in systems engineering and developer tools is reflected in the product’s architecture. As generative AI moves from R&D to mission-critical workflows, Braintrust is becoming the default infrastructure layer for building reliable, high-quality LLM applications.
