Responsibilities

Own end-to-end UI : Go from concept → flows → wireframes → prototypes → production-ready, high-fidelity UI

Build real product : Implement responsive, accessible components in React + TypeScript + Tailwind, using Radix UI / shadcn patterns

Shape complex UX : Partner with Product, Eng, and AI/ML to design clear interactions for real-time, multi-user features

Evolve our design system : Drive tokens, theming, documentation, and component APIs for scalability and consistency

Design with AI in the loop : Integrate AI-assisted design-to-code workflows and author patterns that our agents can reliably compose

Polish the feel : Add motion, micro-interactions, and states that improve comprehension—not just aesthetics

Collaborate in real time : Help build collaborative UX using Liveblocks/WebSockets, optimizing presence, conflict-resolution, and latency

Ship accessible, fast UI : Ensure that all designs adhere to accessibility standards, keep Core Web Vitals green, and measure UX with meaningful product metrics

Required

Portfolio of shipped, product-quality UI that demonstrates strong visual taste and systems thinking. We care less about where you've worked or how long you've been there, and more about what you can create, the rigor behind your process, and the clarity of your outcomes. Case studies should highlight not only polished visuals, but also your approach to design systems, interaction patterns, accessibility, and measurable product impact

Fluency with Figma (flows, prototypes, component props/variants)

Experience building within a design system (tokens, theming, component APIs)

Strong grasp of UX principles, interaction design, and accessibility fundamentals

Interest in AI-augmented workflows (promptable components, agent-safe patterns)
