  • Build performant, accessible, and reusable component libraries that scale across multiple products

  • Lead technical design sessions and drive frontend architecture decisions

  • Optimize application performance for high-volume financial data processing

  • Collaborate with Product, UX, and Engineering teams to translate complex payment workflows into intuitive user experiences

  • Mentor engineers and establish frontend development standards and best practices

You Are:


  • Experienced in balancing rapid feature delivery with code quality, testing, and maintainability

  • Skilled at translating business requirements into scalable technical solutions

  • Proactive in monitoring live systems and troubleshooting production issues

  • Comfortable working with ambiguous requirements and driving clarity through technical discovery

  • Committed to knowledge sharing and building team capabilities through documentation and mentorship

You Have:


  • 6+ years of production experience with modern web technologies (HTML, CSS/SCSS, JavaScript/TypeScript)

  • 3+ years of hands-on React development in complex, data-heavy applications

  • Solid experience with state management solutions (Redux, Zustand, Recoil, or similar)

  • Strong background in testing strategies and frameworks

  • Experience building responsive, accessible web applications

  • Understanding of RESTful APIs and modern build tools

Bonus if you have:


  • Experience in payments, fintech, fraud prevention, or financial services
