  • ▹Ensure new AI capabilities integrate naturally with established product experiences rather than feeling like disconnected features
  • ▹Maintain consistency across products while identifying where emerging AI interactions require new design paradigms
  • ▹Partner with designers and developers to ensure design-system components are practical, scalable, accessible and consistently implemented
  • ▹Facilitate design workshops and collaborative discovery sessions to explore customer problems and AI opportunities
  • ▹Clearly communicate design rationale, research findings, user needs and tradeoffs to technical and non-technical stakeholders
  • ▹Challenge assumptions and advocate for customer-centered solutions when technology or implementation considerations begin driving the experience
  • ▹Provide design leadership and mentorship to other designers and help raise the overall quality of UX across the organization
  • ▹Collaborate across multiple teams and product areas to create coherent end-to-end customer experiences
  • ▹Stay current with emerging AI technologies, interaction patterns and design practices and translate relevant developments into practical product experiences

  • ▹Understanding of large language models (LLMs) and the opportunities and limitations they introduce into product experiences
  • ▹Familiarity with conversational UX and natural-language interfaces
