• Behavioral signals: Thrives in ambiguity; moves fluidly between systems thinking and craft, exceptional communication – able to influence and push back thoughtfully, deep empathy for risk-averse, detail-oriented users, comfort designing in text-dense, information-rich interfaces, experience working with founders or exec teams on product vision
