AI Product Designer

We're seeking an AI Product Designer to design an Agentic system and AI agents for healthcare. The ideal candidate is a product-minded, hands-on designer with deep experience designing LLM/agent interactions (tool use, function calling, RAG, evals) and strong systems-thinking/design-ops chops (ideally with founding-designer experience at a YC/venture-backed startup). This role calls for a dynamic product design leader who can drive end-to-end delivery of agentic workflows and align cross-functional partners across sales, operations, marketing, recruiting, and product. As an AI Product Designer, you will own design strategy, information architecture, and execution of the agent platform and design system.

• Design AI interfaces and agent workflows (chat, tools, actions) end-to-end—from problem framing and user flows to high-fidelity Figma and production QA.
• Collaborate with AI engineers to design interfaces that handle real-time data and dynamic outputs.
• Prototype rapidly using Figma (advanced prototyping), React, Replit, and Cursor; when helpful, use lightweight code in HTML, CSS, and JavaScript or Framer; run usability tests, instrument analytics, and iterate based on controlled experiments and session reviews.
• Simplify complex lab tasks into intuitive layouts and user flows.
• Drive innovation by exploring new AI design opportunities and creating 0→1 designs that push the limits of creative AI applications.
• Contribute to the long-term vision of AI at 3Y, shaping the roadmap and scaling AI capabilities across the company.

• 7+ years in product design (5+ in complex B2B/enterprise); track record shipping AI-powered features or intelligent interfaces at scale.
• Founding designer (YC or venture-backed) experience strongly preferred; portfolio showing systems thinking, data-dense UI, conversational patterns, and a cohesive design system with measurable impact.
• Expert Figma (design tokens, components, advanced prototyping); comfortable with rapid interactive prototyping (HTML/CSS/JS or equivalent).
• Fluency in LLM/agent concepts (prompt patterns, tool use/function calling, RAG trade-offs, evals) and how they inform UX and product design.
• Skilled in product analytics, experimentation, and AI-augmented design workflows (ChatGPT/Claude, Midjourney/DALL·E, Copilot).
• Experience working with cross-functional teams.
• Ability to work 5 days a week in our New York office with a fully in-person team.
