About the role
ABOUT THE COMPANY
Braintrust is the agent observability platform. By actively applying intelligence to agent traces and automatically surfacing the most critical patterns, Braintrust gives teams the visibility to understand how agents behave in production and the tools to improve them.
Teams at Notion, Stripe, Box, OpenAI, and Cloudflare use Braintrust to trace their agents, find the issues in their observability data, and run evals that tell them how to improve.

- A first-class prompt playground experience supporting multiple models across thousands of user inputs.
- A system for prompt management, configuration, and versioned comparisons.
- A fully multiplayer, scalable human review system.
- LLM output analysis and comparison across arbitrarily large datasets.
IDEAL CANDIDATE CREDENTIALS
- Expert-level understanding of Typescript, React, HTML, CSS, SQL, NextJS
- Previous experience founding or working at startups is a plus
- Has written prompts / tinkered with GPT models and apps
