Location: Remote Type: Full-time Company: Ihsan Product: Ihsan Pay Website: https://ihsan.com/ Social Media: https://www.instagram.com/sultansamuelaziz/ YouTube: https://www.youtube.com/@sultansamuelaziz/ Stack: Go, TypeScript, PostgreSQL, React Native, Solana Important requirement Please apply only if you have personally built important backend infrastructure for a live financial product handling real customer funds. We are especially interested in engineers who have worked on: • Stablecoin neobanks or payment wallets • Digital banking or money-transfer platforms • Payment ledgers and balance systems • Card payments and bank-transfer infrastructure • Settlement and reconciliation systems • High-volume financial transaction platforms General frontend, cryptocurrency, NFT, smart-contract or DeFi experience without production payment-backend experience is not sufficient for this position. About Ihsan and Ihsan Pay Ihsan is building a new digital home for the global Muslim community. Our long-term vision is to create a super-app that brings the Ummah together in one place—starting with private communication and expanding into payments, commerce, investment, media, education and more. We believe the Muslim world should have digital infrastructure that reflects its values, protects its independence and makes it easier for Muslims across countries, cultures and languages to connect and do business. Ihsan Pay is the financial foundation of this vision. We are building a global stablecoin neobank that feels as simple and familiar as a modern bank account and is aligned with Islamic principles. Users will be able to hold and use three digital balances: • US dollars through USDC • Euros through EURC • Gold through PAXG We are intentionally focusing on three carefully selected assets—not building a cryptocurrency exchange with hundreds of speculative tokens. Integrated into the Ihsan super-app, Ihsan Pay will allow users to: • Hold US dollars, euros and gold • Send money using usernames and QR codes • Receive instant payments from other Ihsan Pay users • Deposit and withdraw through approved fiat partners • Make local and international payments • Accept payments as a merchant • Use an Ihsan Pay Visa debit card • Use gold as an everyday means of payment • Store, spend and invest without riba (interest) Our mission is to make payments and commerce easier, strengthen economic cooperation across the Ummah (Muslim Community) and contribute to building a more connected and prosperous Ummah.

You will take ownership of the backend systems that ensure every balance, transfer, deposit, withdrawal and card transaction is recorded and processed correctly. When a user deposits $1,000, sends $100 or receives a card refund, Ihsan Pay must always know exactly what happened and what the user s correct balance should be—even when providers send duplicate events, systems temporarily fail or transactions arrive in an unexpected order. Your responsibility will be to make that financial infrastructure reliable, secure and auditable. This is a hands-on engineering position. You will design the architecture and write production code—not only manage other engineers. What you will build • Ihsan Pay s core payments backend • The financial ledger that records every movement of customer funds • Real-time balances for USDC, EURC and PAXG • Internal transfers between Ihsan Pay users • Username- and QR-based payment processing • Deposit and withdrawal workflows through approved fiat partners • Card authorization, settlement, reversal and refund processing • Merchant-payment and settlement infrastructure • Payment state machines and transaction lifecycles • Idempotent APIs that prevent duplicate payments • Reliable processing of provider webhooks and async
