Product Designer (UX, HCI) - AI Applications

About the role

ActAI builds proactive applications for users who are not used to complex prompting, starting with an agent-first mobile communication app. This Product Designer (UX, HCI) role focuses on designing how people use AI in real product workflows, creating HCI interfaces where users can understand, guide, correct and stay in control of AI systems that reason and act across multiple steps.

Key responsibilities

• Design end-to-end user experiences for AI product surfaces, from concept to shipped product.
• Create interaction patterns for human-AI workflows, including prompting, review, confirmation, correction, handoff and recovery.
• Design interfaces that help users understand what the AI is doing, what it knows, what it is unsure about and what will happen next.
• Turn complex, multi-step AI capabilities into clear, controllable flows for everyday use.
• Work with product, engineering and ML teams to define problems, test ideas and ship quickly.
• Produce wireframes, flows, prototypes and high-fidelity designs for web and mobile.
• Run lightweight user research and usability tests to find friction, trust issues and failure points.
• Help define reusable HCI design patterns as the product and design system mature.

Required profile

• Experience as a product designer or UX designer with a portfolio across web or mobile products.
• Ability to simplify complex systems and turn unclear product behavior into clear user experiences.
• Experience working closely with product managers and engineers in fast-moving teams.
• Comfort working with ambiguity and shaping solutions before requirements are fully defined.
• Good judgment on usability, edge cases and failure handling.
• Clear thinking about trust, control, feedback and transparency in AI-driven experiences.

Required skills

• Strong interaction design, information hierarchy and prototyping skills.
• Proficiency in Figma and fast iteration workflows.
