• Conduct user research, usability testing, and design validation activities to inform design decisions.

• Independently lead UX initiatives and drive solutions for complex product challenges.

• Apply established design patterns and contribute to the evolution of our design system to improve consistency, accessibility, and scalability.

• Collaborate with fellow designers through critique, feedback, and shared problem-solving.

• Present design work and rationale clearly to stakeholders, leadership, and cross-functional teams.

• Leverage AI-powered tools and emerging technologies to accelerate research, ideation, design exploration, documentation, and execution.

What Success Looks Like
