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

Founding Designer

San FranciscoOn-site$175K - $200K5 - 10 years
You'll spend mornings in Figma prototyping how a support agent decides when to escalate, 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.
