Accountabilities:

• Design, establish, and continuously improve the fraud prevention framework, including policies, procedures, and risk management strategies tailored to international remittances and cross-border payments.
• Monitor transactions in real time, analyze behavioral patterns, and identify suspicious activities, emerging fraud trends, and potential financial risks.
• Develop, implement, and optimize fraud detection rules and risk controls to reduce fraudulent transactions while minimizing friction for legitimate users.
• Investigate complex fraud cases, manage alerts, assess suspicious activity, and coordinate responses to security incidents.
• Continuously evaluate and improve fraud detection models, monitoring processes, and investigation workflows to strengthen prevention capabilities.
• Identify and address fraud typologies such as identity theft, mule accounts, account takeover, and social engineering.
• Take full ownership of fraud prevention operations, prioritize initiatives according to risk exposure, and make informed decisions in a resource-conscious, high-growth environment.
• Establish the foundations for a scalable fraud prevention function, with the opportunity to develop and lead a team as business needs evolve.

Requirements:

• Significant hands-on experience in fraud prevention, ideally within fintech, digital payments, remittances, or cross-border financial services.
• Proven ability to build fraud prevention policies, procedures, and risk management frameworks from the ground up.
• Strong practical experience in transaction monitoring, fraud investigations, alert management, risk rule configuration, and continuous improvement of detection models.
• Solid understanding of fraud typologies affecting remittances and international payments, including identity theft, mule accounts, account takeover, and social engineering.
• Familiarity with AML/CFT and KYC regulatory frameworks, as well as the compliance considerations associated with financial transactions.
• Strong analytical and problem-solving skills, with the ability to interpret transaction patterns, assess risk exposure, and make data-driven decisions.
• A proactive, hands-on mindset with the ability to balance strategic planning and day-to-day execution without relying on a large team or established infrastructure.
• Excellent prioritization, independent decision-making, and ownership skills, with the ability to operate effectively in a fast-growing environment with limited resources.
• Leadership potential and the ability to establish processes, influence stakeholders, and build a team as the function expands.
• Comfort working remotely and collaborating across geographically distributed teams in Latin America and other international markets.

Benefits:

• Fully remote work, with the flexibility to organize your working day from anywhere in Latin America.
• Additional vacation days to support rest, personal well-being, and work-life balance.
• The opportunity to build and shape a fraud prevention function from the ground up within an innovative fintech environment.
• Significant ownership and autonomy, with the opportunity to influence risk strategy and contribute directly to the security and reliability of international payments.
• Potential to develop and lead a dedicated fraud prevention team as the business scales.
• A dynamic, international, and growth-oriented environment where your expertise can have a meaningful impact.
