UX Designer, AI App

There are over 5 billion users using basic applications today such email, notes, tasks, calendar and they're not AI-native. Our mission is to build proactive applications for anyone in the world, who are not used to complex prompting. We aim 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. We believe products will greatly reduce hallucinations.

Our objective is to organise anyone's life, allowing us all to spend time on valuable and meaningful things.

You will own the UX of ActAI'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.

• 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 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.
