UX Designer

About the role

A1 is building a proactive smart assistant for everyday users to bring intelligence to conversations, errands, organizing, and workflows with minimal prompting. Our product focuses on high reliability for long-running workflows, persistent context, and real-world task completion, handling multi-step reasoning and interactions with external tools despite non-deterministic model behavior. The goal is to help users complete tasks daily with over ~90% reduced time.

You will own the UX of A1's core app experience, designing end-to-end flows users go through every day—how they start tasks, follow along as the AI works, stay in control, and recover when something goes wrong. This is an HCI-focused role requiring deep understanding of both user needs and AI system behavior to create clear, reliable, and controllable product 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 task completion, including handoff, progress tracking, and error recovery.
• Design how the app surfaces AI actions, decisions, and user confirmations or adjustments.
• Map and design the full range of AI states users encounter: loading, thinking, acting, waiting, completing, stalling, failing, and recovering.
• Collaborate with product, engineering, and ML teams to define user requirements and translate them into concrete design solutions.
• Conduct usability research to identify where users lose trust, feel uncertain, or disengage.
• Produce wireframes, user flows, and high-fidelity designs ready for engineering implementation.
• 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.

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 translating 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.
• Strong judgment on usability, edge cases, failure handling, and recovery flows.
