About The Position

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.
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.

Requirements

• Experience as a UX designer on consumer mobile or web apps, with a strong portfolio.
• Solid skills in user flow design, wireframing, and high-fidelity prototyping in Figma.
• Ability to design for systems that are asynchronous, non-deterministic, and context-dependent.
• Clear thinking about user trust, control, feedback, and transparency in AI-driven product experiences.
• Experience conducting user research and turning findings into design decisions.
• Comfortable working in fast-moving teams with evolving product scope.
• Ability to balance simple consumer UX with complex AI system behavior.
• Good judgment on usability, edge cases, failure handling, and recovery flows.

Responsibilities

• 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 app surfaces.
• Design for both simple everyday interactions and complex multi-step AI workflows within the same product.
