Your tasks Champion users and outcomes: Keep a user-first perspective in every decision and make complex packaging and compliance workflows intuitive, clear, and measurable. Conduct user research and discovery: Lead interviews, usability tests, and workshops to understand customer workflows, pain points, and recurring UX friction. Shape workflows and interaction models: Partner with Product and Engineering from early problem framing through solution design, turning complex requirements into coherent end-to-end experiences. Turn recurring problems into reusable patterns: Identify common interaction needs across modules and define scalable UX patterns for areas such as tables, filters, bulk actions, status, review flows, data completeness, and system states. Evolve the UX side of our design system: Maintain and improve interaction principles, components, states, and usage guidance so teams can build consistent experiences without redesigning common problems from scratch. Prototype with AI and code when useful: Use Figma, AI coding tools, and lightweight coded prototypes to test ideas quickly.
