Rainforest Tech Stack

Payments-as-a-Service platform for embedded financial services

Financial Services Atlanta, Georgia 11–50 employees Privately Held

Rainforest operates a PaaS model for embedded payments, targeting vertical software platforms that want to offer payment capabilities without building or licensing infrastructure in-house. The stack (Ruby on Rails, Go, Vue, PostgreSQL, AWS EKS) reflects a platform built for production scale, while active projects around AWS infrastructure scaling, EKS optimization, and CI/CD design signal ongoing work to support growing transaction volume. Hiring velocity is accelerating across engineering and product, with senior-focused hiring suggesting deeper architectural or product work rather than team expansion.
