• Raise the bar for usability, consistency, and product quality across the platform
  
  

Required Qualifications

• 4+ years of experience in product design, frontend product engineering, or hybrid design/engineering roles
• Strong portfolio demonstrating product thinking, UX depth, and visual craft
• Proven experience shipping real, production-grade product experiences
• Strong proficiency with React and modern frontend frameworks
• Working knowledge of React, Tailwind CSS, and component systems such as shadcn
• Ability to take ambiguous problems from concept to production

Preferred Qualifications

• Experience in fintech, payments, crypto, or other highly regulated or complex product domains
