• Partner with data science and engineering to shape model requirements, evaluate performance constraints, and align system behaviors with user needs
• Champion responsible AI principles including transparency, fairness, bias mitigation, and user empowerment across all design work

• Partner with UX Research to run usability testing and AI-specific validation studies to understand user mental models, trust factors, and interaction expectations
• Leverage qualitative and quantitative data to run evaluative studies for AI features (e.g., prompt/response quality, hallucination risk, trust signals)
• Continually iterate and evolve the way we design and learn from our customers
• Demonstrate deep systems-thinking skills and comfort designing across multiple layers: UI, data inputs, model constraints, and operational workflows

Mentorship & Design Excellence

• Mentor and coach designers across the organization, elevating design craft and strategic thinking
• Model best practices in design process, critique, and collaboration
• Identify opportunities to improve design operations, tools, and processes that benefit the broader design organization
• Leverage AI tooling and internal content standards to deliver clear, concise, brand-aligned product experiences
• Design accessible solutions and collaborate with the Accessibility team to ensure WCAG compliance, using AI checks alongside expert review
