UX Designer

ABOUT A1 There are over 5 billion users using basic applications today such email, notes, tasks that are not AI-native. Our mission is to build a proactive smart assistant for everyday users to bring intelligence to conversations, errands, organising and workflows, with minimal prompting. 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. Our objective is to help users complete tasks daily enjoyable with over ~90%* reduced time. ROLE You will own the UX of A1's core app experience. This means designing the end-to-end flows users go through every day - how they start tasks, how they follow along as the AI works, how they stay in control, and how they recover when something goes wrong. This is a UX role for a HCI product. You need to understand both user needs and AI system behavior well enough to design product flows that feel clear, reliable, and controllable. WHAT YOU'LL BE DOING - Own UX for A1's core app surfaces across iOS, Android, and web. - Design complete user flows for AI-assisted tasks - from intent capture through to task completion, including handoff, progress tracking, and error recovery. - Design how the app surfaces what the AI is doing, what decisions it has made, and what the user needs to confirm or adjust. - Map and design the full range of AI states a user encounters - loading, thinking, acting, waiting, completing, stalling, failing, and recovering. - Work with product, engineering, and ML teams to define user requirements and translate them into concrete design solutions. - Conduct usability research to understand where users lose trust, feel uncertain, or disengage. - Produce wireframes, user flows, and high-fidelity designs that engineering can build from directly. - Contribute to the design system and shared UX patterns for AI ap
