About The Role

A1 is building a proactive AI chat app for everyday users to bring intelligence to conversations, errands, organising and workflows. Unlike traditional chat-based applications, 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 behaviour.


What You’ll Be Doing

* Lead end-to-end design for one or more AI product surfaces, from early concept to production.
* Design core user flows that make advanced AI capabilities feel simple, natural, and usable.
* Work closely with product, engineering, and ML teams to explore problems, test ideas, and ship quickly.
* Create wireframes, user flows, prototypes, and high-fidelity UI for web and mobile.
* Rapidly prototype and iterate on new interaction models, especially for AI-driven experiences.
* Conduct usability testing and synthesize insights to refine product direction.
* Help define and evolve A1’s design system to support speed, consistency, and scalability.
* Advocate for user experience while balancing product velocity and technical constraints.


What You Will Need

* Proven experience as a product or UX designer, with a portfolio spanning web and mobile products.
* Strong proficiency in Figma and rapid prototyping tools.
* Solid understanding of interaction design, layout, hierarchy, and visual systems.
* Experience working closely with engineers and product partners in fast-moving environments.
* Comfort designing from incomplete inputs and evolving requirements.
* Ability to simplify complex workflows into clear, intuitive user experiences.
* Willingness to take ownership from problem definition through shipped solution.


Nice to Have

* Experience designing AI-powered or data-heavy products.
* Familiarity with usability testing and qualitative research methods.
* Experience working on zero-to-one products or early-stage teams.
* Interest in emerging UX patterns for AI, automation, or intelligent systems.


Outcomes

* Own the end-to-end AI interaction experience, from first discovery to repeated use.
* Ensure AI behaviors are predictable, intuitive, and trusted by users.
* Take responsibility for the clarity, usability, and effectiveness of complex workflows.
* Detect friction or confusion proactively and design solutions that prevent issues before they reach users.
* Own the translation of research and engineering capabilities into coherent, usable product experiences.
* Define and track success metrics for AI UX, and iterate designs based on real user behavior.
* Mentor and influence other designers and cross-functional teams on AI interaction standards.
* Make high-impact design decisions that balance speed, technical feasibility, and long-term system quality.
* Drive a design philosophy that becomes a foundation for all future AI product surfaces.
