Our mission is to build a proactive smart assistant for everyday users 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. The system must handle multi-step reasoning, interact with external tools, and remain reliable despite non-deterministic model behavior. Our objective is to help users complete tasks daily enjoyable with over ~90%* reduced time. 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.

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.
