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.

About the role

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.

In this role, you will:

  • Play a significant role in developing the core user experience of our product. You will work across UI, API, and SDK, ensuring that Braintrust is a seamless tool in every AI engineer’s work day.

  • Work closely with our users to deeply understand their needs and contribute to the product roadmap. You are comfortable owning the entire product lifecycle from gathering requirements to ideating, designing, and implementing.

  • Partner closely with our product and engineering teams. You’ll work to establish and implement a design system that enables rapid product iteration.

Ideal candidate credentials

  • You have experience designing zero to one B2B products with complex requirements.

  • You enjoy building things and are familiar with modern devtools (send us a link to your Github!).

  • You have owned problems end-to-end, and are willing to pick up whatever knowledge you’re missing to get the job done.

  • You have thrived in environments where things are sometimes loosely defined and may have competing priorities or deadlines.

Benefits include

  • Medical, dental, and vision insurance

  • Daily lunch, snacks, and beverages

  • Flexible time off

  • Competitive salary and equity

  • Wifi & cellphone stipend
