What’s your challenges
Drive user insight through rapid exploration

• Own and lead our user research practice, with a strong bias toward early, prototype-driven user testing.

• Default to using AI-assisted prototyping to quickly explore ideas, validate assumptions, and surface risks before engineering investment.

• Turn ambiguous feedback and fragmented requests into clear hypotheses, prototypes, and learnings that guide product direction.

Set the bar for product design

• Define and evolve our design philosophy and principles, including how we balance speed vs. polish and AI-enabled workflows vs. traditional processes.

• Ensure design decisions are grounded in evidence from real users, not opinions or hierarchy.

Make design a force multiplier

• Build, scale, and maintain a design system that encodes user insight and enables teams to move fast with confidence.

• Champion modern tools and workflows—especially AI—that reduce cycle time from idea → prototype → user feedback → decision.

Lead and grow the design team

• Lead and coach a team of product designers to adopt prototype-first, research-led workflows.

• Set expectations that learning happens through making, testing, and iterating—not long handoffs or static specs.

• Stay hands-on when needed: prototyping, testing flows with users, and unblocking high-impact work.

Partner deeply across the company

• Work shoulder-to-shoulder with Product and Engineering to ensure learning velocity drives roadmap and prioritization.

• Help the organization build shared understanding of users through prototypes, narratives, and clear synthesis—not just documents.
