About the Role
You will build and own payment products used by 10,000+ merchants—payment gateways,
merchant dashboards, KYC systems, and subscription engines. You’ll work in a small squad (2-4
engineers) with end-to-end responsibility from database schema to production deployment.
AI tools (Cursor, Claude, Copilot) are part of daily workflow. You’ll use them to accelerate
development—scaffolding, debugging, documentation—while applying your judgment for
security, edge cases, and business logic.
