📈 Primary Responsibilities

• Own and drive the User Experience (UX) design for Bjak's core AI application across iOS, Android, and web platforms.

• Design comprehensive user flows for AI-assisted tasks, from initial intent capture through to successful task completion, including seamless handoffs, progress tracking, and robust error recovery strategies.

• Develop intuitive interfaces that clearly communicate the AI's current actions, decisions made, and any user confirmations or adjustments required.

• Map and design the full spectrum of AI states users may encounter, such as loading, thinking, acting, waiting, completing, stalling, failing, and recovering.

• Collaborate effectively with product managers, engineers, and ML specialists to define user needs and translate them into actionable design specifications.

• Conduct user research and usability testing to identify areas where users experience a loss of trust, uncertainty, or disengagement.

• Produce detailed wireframes, user flows, and high-fidelity mockups and prototypes that engineering teams can directly implement.

• Contribute to the development and maintenance of the design system and shared UX patterns for AI-powered application surfaces.

• Design for a diverse range of user interactions, from simple, everyday tasks to complex, multi-step AI workflows within a unified product experience.

📝 Enhancement Note: The emphasis on "owning UX" and designing "complete user flows" indicates a significant level of autonomy and responsibility.
