Product Designer (UX)

BJAK San Francisco, California

### **About the Role**

A1 is building a proactive AI system that carries work forward across conversations, tools, and time.

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 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.
