If you are a deeply skilled, execution-focused designer who takes pride in shipping beautiful, high-performing interfaces, this role was built for you.

• You are a craftsperson first, you produce design work that is precise, considered, and visually distinctive.
• You have a commercially focused design aptitude, and know how to strike a good balance between high conversion and premium brand presentation in a fast moving environment. You understand key engagement and DTC KPIs that drive funnel optimization.
• You have strong opinions about UI quality and can articulate and defend design decisions to stakeholders at all levels.
• You move fluidly between big-picture thinking and pixel-level execution without losing momentum.
• You are familiar with and utilize AI tools in order to ideate and optimize your workflow.
• You are proactive about identifying friction in the current experience and come armed with solutions, not just observations.

• Drive iterative UI improvements grounded in performance data, heuristic review, and competitive benchmarking, not just aesthetic preference.
• Develop motion and interaction design specs for key micro-interactions, transitions, and animated elements where they enhance the customer experience. (A strong plus.)
• Contribute to and review creative executions, ensuring campaign landing pages, editorial features, and seasonal moments stay on-system.
• Present design work to cross-functional stakeholders and leadership, providing clear rationale and context for design decisions.
• Actively champion design quality across the organization — raising the bar, educating partners, and pushing back thoughtfully when standards slip.
• Own research strategy, not just execution:
