The PSP system processes payments for our services worldwide. We are looking for a Payment Processing Developer who will help integrate new partners into the system and support additional payment methods. You will work on the core of our cashless payments platform, which processes payments across multiple services—from Taxi to Advertising—and operates globally, from South America to Qazaqstan. The system handles hundreds of transactions per second, connects to dozens of acquirers, and supports cards, e-wallets, Apple Pay, and other payment methods. It is built in Golang using a userver-like framework and is already used in production. The team is focused on expanding payment capabilities, connecting partners and countries, and improving system infrastructure and reliability.
