emerchantpay Tech Stack

Global payment processor supporting cards, wallets, and alternative methods

Financial Services London, England 201–500 employees Founded 2002 Privately Held

emerchantpay operates a multi-rail payment platform connecting businesses to global acquiring, local payment methods, and fraud protection. The stack is deliberately polyglot—Ruby on Rails and Python for core services, .NET for enterprise integrations, Go for performance-critical layers—paired with Redis, RabbitMQ, and managed AWS infrastructure. Active hiring skews senior and engineering-focused (8 of 15 roles), with explicit pain points around AI-assisted systems, PCI-DSS compliance, and scaling highly available infrastructure; suggests the company is balancing rapid feature velocity against reliability and security demands in payments.
