Chargeback Analyst at CloudWalk. Location Information: Brazil. If you like digging into transactions, spotting patterns others miss, and turning messy dispute data into a clear story, this one’s for you.. What You'll Do. Analyze disputes and chargeback flows to decide the right action. Investigate cases end-to-end (transaction timeline, evidence, money flow, root cause). Build and review representment/defense cases — clear, well-documented, win-oriented. Dig into data to find patterns, fraud signals, and process gaps worth fixing. Use (and help improve) our AI/automation tooling to handle disputes faster and smarter. Partner with teams across CloudWalk (Risk, Compliance, Product, Data, Engineering). What we need from you. Comfortable using LLMs/AI tools in your daily work — and curious about agent frameworks (LangChain, Mastra, etc.). Some coding/scripting comfort (reading code, SQL, light automation) — you don’t need to be an engineer. Strong analytical thinking and curiosity (“why did this happen?” is your default mode). Problem-solver mindset + strong desire to learn (new stuff daily). Attention to detail + ability to prioritize a busy queue. Great writing for case summaries, dispute defenses, and Slack updates. Clear communication in threads/huddles/DMs. Ownership mindset — you spot what’s broken, propose better ways of doing things, and drive decisions, not just execute them.. High integrity and discretion with sensitive financial data. Join us at CloudWalk, where we’re not just engineering solutions; we’re building a smarter, AI-driven future for payments and credit—together..
