You will work with product, engineering, and ML teams in a fast-moving environment, produce wireframes and prototypes for web and mobile, run quick usability tests, and help define reusable HCI design patterns as the product matures.

Qualifications

• 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 into clear user experiences.
• Experience working 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 and failure handling.
• Clear thinking about trust, control, feedback, and transparency in AI-driven experiences.

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, and recovery.
• Design interfaces that show 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 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 and trust issues.
• Help define reusable HCI design patterns as the product and design system mature.

Job description

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

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

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.
