**What’s the opportunity?** Join dLocal’s Fraud Prevention Buyer Strategy team, responsible for the fraud strategy behind buyer\-side card transactions across dLocal’s merchant portfolio — balancing fraud performance with conversion so the business can grow safely. As Team Leader, you’ll set the direction for a portfolio of merchants and lead the analysts working on it, partnering closely with Data Science, IT, and Commercial to turn the team’s priorities into coordinated initiatives. You’ll also champion AI\-enabled automation and process improvements that cut manual work and scale the team’s capacity. **What will you be doing?** * Oversee a portfolio of merchants, monitoring fraud and conversion performance and guiding actions to keep results on target. * Lead, coach, and support a team of analysts, helping them prioritize work and develop their fraud\-prevention capabilities. * Set priorities with Data Science, IT, and Commercial, translating dLocal’s needs into clear objectives and coordinated initiatives. * Drive AI\-based automation initiatives — both by guiding the team’s projects and by building and implementing solutions yourself. * Identify repetitive or error\-prone processes and work with relevant partners to implement tools, scripts, integrations, or workflow improvements. * Use data and performance trends to assess fraud strategies, identify opportunities for improvement, and inform decisions. * Communicate recommendations and priorities clearly, building effective working relationships across Fraud Prevention and partner teams. **What skills do you need?** * Bachelor’s degree in Economics, Engineering, Statistics, or a related field. * Experience in fraud prevention, including managing fraud scores. * Strong analytical skills and the ability to use data to monitor performance, investigate trends, and support decisions. * Proficiency in SQL for querying and analyzing data; knowledge of Python or another programming language is a plus. * Hands\-on experience with AI tools and machine\-learning concepts — able to identify opportunities and build solutions yourself, not only guide others. * A proven track record leading and coaching teams, with the ability to guide analysts and collaborate across teams. * An automation mindset: able to spot opportunities to reduce manual effort and improve process quality and scalability. * Advanced English (mandatory).
