GMO Payment Gateway operates Japan's largest payment processing network, handling multiple payment methods (QR codes, smartphone payments, BNPL) across financial institutions and merchants. The company is mid-sized but deliberately hiring for sales (20 roles) and finance (11) while actively adopting security and AI infrastructure (AWS WAF, CSPM, XDR, EDR, SASE, RAG) — signaling both merchant expansion and internal modernization of fraud detection and compliance systems, particularly around credit accuracy and legacy process automation.
