About this role
Join A1 to design and build human-centered interfaces for AI-native applications. You'll prototype cutting-edge interaction patterns for web and mobile, focusing on making AI behavior understandable and controllable within real workflows—this is greenfield HCI work, not maintenance.
What you'll do

- Create functional prototypes demonstrating streaming responses, multi-step workflows, and real-time feedback loops
- Design UI patterns that communicate progress, uncertainty, confidence, and failure states to users
- Build interfaces enabling users to supervise, correct, and redirect AI behavior
- Develop reusable frontend components and contribute to architecture for AI product surfaces
- Collaborate with product, design, and ML teams to validate interaction concepts rapidly
What they're looking for
- React and TypeScript
- Interaction design and experimental UI development
- Animation and CSS/frontend performance optimization
- Product and UX intuition
- Rapid prototyping in ambiguous environments
- HCI principles and designing for trust and transparency
- State management and frontend architecture
- Cross-functional collaboration between design and engineering
