Product Designer (UX)

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 behavior.

You will shape how users experience AI from the ground up. This is an early, high-ownership role where your design decisions will directly influence core user flows, interaction models, and product direction. You will design systems and journeys – how users discover value, interact with intelligence, and build trust in an AI-driven product.

What Youll 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 A1s 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.

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 the hands of our users a truly magical product.

Interview process

If there appears to be a fit, well reach out to schedule 3, but no more than 4 interviews. Applications are evaluated by our technical team members. Interviews will be conducted via virtual meetings and/or onsite. We value transparency and efficiency, so expect a prompt decision.
