Simplify dense information

Job description

A UX or product designer in this setting usually turns complex model training workflows into clear, usable interfaces. A strong candidate brings a portfolio of shipped product work, comfort with technical users, and the ability to simplify dense information. Since the company builds tools for long horizon AI tasks, the designer should be curious about how developers and researchers actually work.

How it fits the AI era

AI changes design work by speeding up mockups, copy, and research synthesis, so the craft shifts toward judgment and problem framing. What stays human is understanding user intent, deciding what matters, and testing real behavior. A designer here helps shape how people interact with specialized models, not just how screens look.

How it builds AI experience

This role builds AI experience by designing for model training and evaluation workflows, where the user is often technical. A designer can grow that skill by learning how post training works, studying developer tools, and prototyping with AI features. Over time, that knowledge becomes a strong edge in AI product design.

Worth showing

• Complex workflow design
• User research practice
• Prototyping with AI
