UI/UX Engineer

A1 is building an AI-native proactive smart assistant. The UI/UX Engineer role sits at the intersection of design and engineering, building AI interfaces that users interact with, prototyping new HCI interaction patterns for AI-driven experiences.

• Build and prototype AI-native product interfaces across web and mobile.
• Create functional prototypes of new HCI interaction models, including streaming responses, multi-step task flows, real-time feedback loops, and system state visibility.
• Translate design concepts into working code with high attention to usability, responsiveness, and motion.
• Experiment with UI patterns that show progress, uncertainty, confidence, failure, and recovery clearly to users.
• Build interfaces that let users supervise, correct, and redirect AI behavior without micromanaging the system.
• Work closely with product, design, and ML teams to validate interaction ideas quickly.
• Contribute to frontend architecture and reusable UI components for AI product surfaces.
• Identify and fix usability, performance, and state management issues in AI-driven interfaces.

• Strong frontend engineering skills in React, TypeScript, or equivalent.
• Experience building interaction-heavy or experimental interfaces.
• Strong product and UX instincts - you can tell when something is unclear or broken from a user's perspective.
• Ability to prototype rapidly in ambiguous environments with incomplete specs.
• Understanding of animation, responsiveness, frontend architecture, and UI performance.
• Interest in HCI interfaces and how to design for trust, control, transparency, and recovery.
• Comfort working at the boundary of design and engineering without clear handoffs.
• Ability to move fast while keeping the user experience clear and usable.
