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 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.

Role

Design how people use AI in real product workflows. This role focuses on building HCI interfaces where users can understand, guide, correct, and stay in control of AI systems that reason and act across multiple steps.

Current UX patterns are not enough for proactive AI products. You will help define new interaction models for how users work with AI, review progress, recover from mistakes, and build trust in the system.

What You'll Be Doing
  • 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 flows that are clear, controllable, and usable in everyday contexts.

  • Work closely 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 identify friction, trust issues, and failure points.

  • Help define reusable HCI design patterns as the product and design system mature.

What You Will Need
  • Experience as a product designer or UX designer, with a portfolio across web or mobile products.

  • Strong skills in interaction design, information hierarchy, and prototyping.

  • Proficiency in Figma and fast iteration workflows.

  • 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.

How We Work

The best products today in the world were built by small, world class teams. We are a high talent density and hands-on team. We make decisions collectively, move at rapid speed, striking a balance between shipping high quality work and learning. Joining our team requires the ability to bring structure, exercise judgment, and execute independently. Our goal is to put in hands of our users a truly magical product

 
Interview process

For design roles, we expect candidates to submit a portfolio as part of the application process.

If there appears to be a fit, we'll reach out to schedule 2 rounds of interviews and a design assessment.

Applications are evaluated by our team members. Interviews will be conducted via virtual meetings and/or onsite.

We value transparency and efficiency, so expect a prompt decision. If you've demonstrated the exceptional skills and mindset we're looking for, we'll extend an offer to join us. This isn't just a job offer; it's an invitation to be part of a team that's bringing AI to have practical benefits to billions globally.benefits to billions globally.
