  • Design Generative AI chat and Ask AI experiences from an interaction and UX systems perspective
  • Own the surrounding UI and experience layer for chat: task panels, summaries, follow-ups, action bars, results views, history, and controls. ups, action bars, results views, history, and controls. ups, action bars, results views, history, and controls
  • Define agent behaviors, capabilities, and boundaries in the UX (when AI offers suggestions, asks for clarification, or escalates), ensuring users remain in control
  • Translate conversation strategies (provided by Conversational Designers) into scalable UX patterns, clear affordances, and actionable response formats (e.g., cards, checklists, tables, next steps)
