- Implement secure payment flows (device binding, authentication, encryption)
- Ensure end-to-end transaction security and data protection
- Manage transaction lifecycle, logs, and reconciliation
- Collaborate on integrations with rewards, wallet, and checkout systems
[Required Experience]
- 3–8+ years of backend engineering experience
- Fintech/payments experience (mandatory)
- Experience in high-scale consumer apps
- Strong understanding of UPI architecture & flows
- Experience with bank/PSP integrations
- Solid understanding of security in fintech systems:
- Encryption (data in transit & at rest)
