Payments platform for retail, ecommerce, and B2B merchants
Quantum ePay operates a PHP and React-based payments platform built on AWS, MySQL, PostgreSQL, and Kafka. The tech stack reflects a mature payments backend (Redis for caching, Postgres for transactional consistency) paired with modern frontend tooling. Active hiring focuses on senior engineering and finance roles, while pain points center on observability, transaction validation at scale, and cross-department coordination — suggesting the company is scaling infrastructure and financial operations in tandem.
