UX Designer

About This Role

This UX role is for a Human-Computer Interaction (HCI) product, focusing on ActAI's core application experience. It involves designing the end-to-end user flows for a mobile communication app, ensuring clarity, reliability, and control as users interact with AI-driven tasks. The designer needs to understand both user needs and AI system behavior to create intuitive 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 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

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

Application Process

• Submit a portfolio as part of the application process
• Two rounds of interviews
• Design assessment
• Applications are evaluated by team members
• Interviews will be conducted via virtual meetings and/or onsite
