Puraido | Senior/Staff Backend/Fullstack SWE | On-site/Hybrid/Remote | Bangkok (Thailand) | Full-time

At Puraido, we're building a B2B payment orchestration platform focused on recurring payments. Our system integrates multiple payment gateways into a single easy-to-use platform. It handles order processing, payments, email notifications, third-party callbacks and risk management. We face ongoing challenges from the constantly changing payment landscape with each payment channel requiring immense flexibility from our platform.

This gives our project - in my opinion :) - a unique edge.
