We expect a broad range of design skills, exceptional taste, and fluency with the latest AI design workflows. 

What you'll own 

• Design end to end across our vendor-facing and internal surfaces: research, flows, UI, and the details that make it usable at volume.

• Ground decisions in analytics and real usage data rather than preference alone. 
• Build and maintain a design system that holds up as the product and the team grow. 
• Give engineering enough clarity to build confidently, without needing pixel-perfect specs for everything. 

Requirements 

• 5+ years designing digital products for mobile and web. 
• A portfolio that demonstrates both design sensibility and real product depth. 
• Demonstrated research ability: you can plan it, run it, and turn it into direction. 
• Fluency with AI tools, with the ability to work directly in code rather than relying solely on prompts. 
• Strong Figma fundamentals: components, auto layout, variables, and systems that hold up under other people's hands. 
• Excellent communication, with a track record of working effectively with US-based stakeholders. 

Nice to have 

• Experience in retail, fueling, or loyalty domain products. 
• Experience improving user flows in complex domains with a large user base and high event volume. 
• Motion and brand design skills you can apply to product and marketing surfaces.
