Description

About Us CUBE3.AI is an innovative fraud prevention platform dedicated to real-time fraud and crypto crime prevention. Our proprietary AI models protect digital assets and transactions from fraud, cyber exploits, and compliance risks. We foster a transparent, efficient, and inclusive digital economy, ensuring safe transactions for both businesses and end consumers. About the Role We’re on a mission to make the financial industry safer and more transparent. As a Fullstack Engineer (Frontend Focused), you’ll build intuitive, high-performance user interfaces that help users detect threats, investigate suspicious activity, and stay in control of real-time transactional events.
