• Implement secure frontend practices (device binding flows, session handling)
• Optimize latency, rendering performance, and API interactions
• Ensure high reliability UX for critical payment journeys
• Collaborate closely with backend, product, and design teams

Required Experience

• 3–6+ years frontend engineering; experience building fintech/payment interfaces is mandatory
• Experience in high‑scale consumer apps
• Engineers who understand user trust in payment experiences
• Strong ownership of performance, reliability, and UX quality
• Attention to detail in edge cases and failure scenarios

• Strong understanding of UPI user flows and payment UX patterns (intent flows, collect, QR, transaction state handling)
• Proficiency in React / React Native / Flutter (or similar) with JavaScript/TypeScript
• Strong focus on performance optimization, edge case handling, and graceful error states
• Secure frontend practices (token storage, session management, auth flows, and sensitive data handling)
• Ability to build trust‑first payment UX: clear transaction states, failure handling with retry, user‑safe confirmations
• Experience with real‑time systems (webhooks, polling, sockets for live status updates)
• Exposure to wallets, rewards, or transaction history systems in consumer‑facing products
• Familiarity with design systems and component libraries (building or consuming)
• Exposure to CMS‑driven storefronts and dynamic layout rendering
