Backend engineer stablecoin

Описание:
Ihsan Pay is building a self-custodial stablecoin payment system designed to feel as simple and familiar as a modern bank account. Integrated into the Ihsan messenger, it enables users to hold stable coins and PAXG, transfer and receive money, accept merchant payments, convert between fiat and crypto, and spend through a stablecoin-connected Visa debit card.

• Build secure and scalable backend payment services
• Integrate wallet, blockchain, KYC, on-ramp, and card providers
• Ensure Ihsan Pay cannot independently access users' self-custodial funds
• Build a financial ledger
• Design reliable transaction-status and reconciliation systems
• Establish security standards and review payment-related code
