Full Job Description

COMPANY A1 is building a proactive AI smart assistant for everyday users to bring intelligence to conversations, errands, organising and workflows. Our product focuses on achieving high reliability for long-running workflows, persistent context, and real-world task completion. The system must handle multi-step reasoning, interact with external tools, and remain reliable despite non-deterministic model behavior. ROLE You will sit at the intersection of design and engineering, building the AI interfaces that users actually interact with. This is not a UI maintenance role. You will prototype, test, and ship new interaction patterns for AI-driven experiences where established conventions do not yet exist. This role is focused on HCI - building interfaces that make AI behavior understandable, controllable, and useful in real workflows. WHAT YOU'LL BE DOING - 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. WHAT YOU WILL NEED - 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. - Abili
