Description

• Integrate fiat payment methods (cards, bank transfers, e-wallets, local payment rails) through payment service providers, gateways, and aggregators • Build and operate core money-handling flows: deposits, withdrawals, refunds, payouts, chargebacks, and settlement • Design and develop ledger and balance-tracking systems that keep money movement accurate and auditable • Guarantee transactional integrity across distributed systems — idempotency, consistency, exactly-once processing, and safe retries • Handle PSP webhooks, callbacks, and asynchronous status updates, including reconciliation against provider records • Build and optimize scalable, low-latency Node.js services supporting high-throughput transactional workloads • Ensure the performance, reliability, and security of payment APIs • Collaborate cross-functionally with product, risk/fraud, finance, and other engineers to ship end-to-end payment features • Contribute to best practices across code quality, testing, CI/CD, and deployment, and share payments domain knowledge with the team

🎯 Exigences

• 5+ years of professional backend software engineering experience • Hands-on experience integrating fiat payments, either through internal systems or via PSP/gateway APIs • Strong understanding of transactional correctness: idempotency, consistency, concurrency, and handling money safely under failure conditions • Proficiency with Node.js and building scalable back-end services • Experience with relational databases, ideally PostgreSQL • Solid grasp of distributed systems and client-server architecture • Experience with CI/CD pipelines and modern development workflows • A security- and reliability-first mindset
