Design Engineer
Braintrust is seeking a Design Engineer to develop the core user experience for their AI observability platform. This role involves working across UI, API, and SDK, deeply understanding user needs to contribute to the product roadmap, and partnering with product and engineering to establish a design system.
Braintrust is the AI observability platform. 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.
We're looking for a design engineer who loves working on complex problems and designing products that power-users love to use on a daily basis. Our primary users are engineers and PMs at innovative tech companies who spend multiple hours a day using our product to run experiments, analyze user behavior, and try out new ideas, seamlessly shifting between their code and our UI.
