UX Designer

About the role

You will own the UX of ActAI's core app experience, designing the 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 a UX role for an HCI product, requiring deep understanding of both user needs and AI system behavior to create clear, reliable, and controllable product flows.

Responsibilities

• Own UX for ActAI'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 what the AI is doing, the 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.

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.
