Data Analyst

About the role

The Risk Team at CloudWalk is expanding to protect millions of merchants and users from fraud, financial crime, and bad actors. This team builds and owns detection logic, interfaces with legal, compliance, and customer support teams, and leverages AI tools as a force multiplier.

Responsibilities

• Hunt fraud at scale
• Build and own detection logic: rules, models, automated monitors, and alert systems
• Dig deep into transaction data to find patterns nobody else notices — 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

Requirements

• Strong SQL skills
• Programming chops (Python is your friend here)
• An 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)
• A curious mind that doesn't turn off at 6pm

Qualifications

At CloudWalk, we envision a future where AI empowers every field to reach new heights. This role is part of our commitment to building a smarter, AI-driven future for payments. We are looking for individuals who can contribute to this vision.
