• 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
• Strong communication skills and experience collaborating cross-functionally
• Comfort operating in fast-paced, high-ownership startup environments
  
  

Preferred Qualifications

• Experience in fintech, payments, crypto, or other highly regulated or complex product domains
• Experience designing and building workflow-heavy or systems-driven products
• Experience building or scaling a design system
• Early-stage or high-growth startup experience
  
  

What we offer

• Competitive compensation including base salary, performance bonus, and meaningful ownership

• Collaborative and innovative work environment with world-class investors
• Direct impact on product direction and company trajectory during a hypergrowth phase
