What You'll Be Doing:
• Build and own detection logic: rules, models, automated monitors, and alert systems
• Dig deep into transaction data to find patterns nobody else noticed — then turn that into a decision, a process, or a new control
• Work alongside engineers to ship real-time risk solutions that actually land in production
• Interface with legal, compliance, and customer support teams when investigations get complex
• Leverage AI tools as a force multiplier
What You Need To Succeed:
• Programming chops (Python is your friend here)
• Analytical mindset with a bias for conclusions over hypotheses
• The ability to make a call with imperfect information and own it
• Fluent Portuguese + solid English (we read a lot of docs in both)
• Curiosity that doesn't turn off at 6pm
We believe the best risk analysts in the next decade won't be the ones with the most experience — they'll be the ones who figured out how to work with AI most effectively. At CloudWalk, that future is already here. Our analysts are already running investigations alongside AI agents, automating workflows that used to take hours, and making decisions backed by real-time intelligence that would've been impossible five years ago.
If you want to be at the frontier of what fraud prevention actually looks like when you pair sharp human judgment with cutting-edge AI — this is the team.
