Founding Payments Engineer – Backend & Blockchain

Full-time/Company: Ihsan

Ihsan Pay is building a self-custodial stablecoin payment system that feels as simple and familiar as a modern bank account.

Responsibilities:

- Own the architecture of Ihsan Pay from prototype to production
- 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
- Design reliable transaction-status and reconciliation systems
- Document architecture and operational procedures; recruit and mentor future payments engineers

Requirements:

- Strong production backend experience with Go, TypeScript or a comparable language
- Experience building or integrating blockchain wallets and transactions
- Practical experience with Solana and SPL tokens
- Experience with payment APIs, webhooks, idempotency and reconciliation
- Strong understanding of private-key security, transaction signing and wallet recovery
- Experience with PostgreSQL and scalable backend systems
- Clear communication and strong technical documentation; security-first approach to financial infrastructure

Nice to have:

- Experience with Privy, Turnkey, Web3Auth or similar embedded-wallet infrastructure
- Experience with USDC, USDT or stablecoin payment products
- Experience integrating on/off-ramps, card issuers or payment processors
- Experience with Helius or other Solana infrastructure
- Experience with QR payments or merchant checkout systems
- Experience building consumer fintech, wallets, remittance or neobanking products

Stack:

Benefits:

- Take technical ownership of a new payment system from its foundation
- Build a product designed for meaningful global use
