About this role
ABOUT ACTAI
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 to no prompting.
Our first application is an agent-first mobile communication app. We believe building applications that users use daily for communication, coordination and collaboration needs will help integrate AI into their lives. The net effect is to eliminate misinformation, achieve low coordination costs, enable high quality tasks and collaboration at scale with minimal or little prompting.
ROLE
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.
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.
