Job description

AI-native startup building agents that resolve customer tickets without human handoff

You’ll spend mornings in Figma prototyping how a support agent decides when to escape, then afternoons shipping those interfaces directly in React and Next.js. This is the founding design seat: you’re establishing the visual grammar for a product where AI is the primary user and humans supervise. Expect to build systems, not screens—designing for uncertainty, confidence thresholds, and conversation repair.

What we’re looking for:

• 5–10 years designing complex software, with a portfolio showing interaction systems for technical or enterprise users
• Fluency in Figma prototypes that engineers can actually build from, plus hands‑on HTML/CSS/React skills
• Experience designing AI products or interfaces with probabilistic outputs, not just deterministic workflows
• Confidence establishing brand voice and visual identity from near‑zero, then documenting it for scale
• Able to be in San Francisco or New York offices with the early team
• Must be based in the United States.

Tech stack:

Figma, HTML, CSS, React, Next.js
