About The Position

At Snaplii, risk management isn't a "brake" on growth—it’s the "supercharger" that enables our 300% explosive expansion.

Today, Snaplii is evolving beyond a digital wallet into infrastructure for AI-native commerce — enabling secure, programmable transactions between users, brands, and AI agents. AI drives demand. Snaplii executes the transaction. We are looking for a Risk Leader with deep fraud expertise and raw analytical horsepower. This role will shape and implement cutting-edge risk strategies that drive sustainable growth, minimize losses, and enhance the customer experience. The ideal candidate has direct experience in payment fraud detection and prevention, with the ability to spot fraudulent transactions and translate fraud patterns into scalable, data-driven solutions.
