Senior Product Designer, UI/UX

• Partner with AI researchers to identify best-in-class UI and UX patterns, and turn them into clear principles and rubrics that define what great design looks like.
• Build polished, interactive web prototypes, in code or with AI-native tools such as Cursor, v0, Lovable or Bolt, that showcase strong and diverse design patterns across many product categories.
• Review AI-generated interfaces and prototypes, and give specific, actionable written feedback on layout, hierarchy, interaction, motion and visual polish.
• Explore a wide range of visual styles, frameworks and animation approaches, from focused productivity tools to playful consumer apps and games.
• Collaborate with other designers and researchers to keep standards consistent and keep raising the quality bar.

• 7+ years of experience as a product designer, design lead, design engineer, or creative front-end engineer at a product- or design-led company (for example Apple, Airbnb, Stripe, Figma, Linear, Spotify or Notion) or a top design agency.
• Hands-on prototyping skills: you build working web prototypes yourself, in code (HTML, CSS, JavaScript, React, Tailwind) or with AI-native tools (Cursor, v0, Lovable, Bolt, Framer).
• A strong grounding in user-centered design, interaction design and rapid prototyping.
• Senior-level design judgment, and the confidence to set direction and explain clearly why a design works.
• Ability to engage reliably for 40 hours/week during weekdays.
• Clear written communication and the ability to give precise, constructive design feedback.

• Fluency with motion and animation (Framer Motion, GSAP, Rive, Lottie, After Effects) or 3D and WebGL, and game design experience in 2D or 3D.
