About CloudWalk:
We are not just another fintech unicorn. We are a pack of dreamers, makers, and tech enthusiasts building the future of payments. With millions of happy customers and a hunger for innovation, we're now expanding our neural network - literally and metaphorically.


About the role
  • We’re looking for a Chargeback Analyst with a strong interest in AI and automation to help us scale and evolve our dispute operations through technology.
  • You’ll work alongside product managers, data scientists, and engineers to bring automation to every layer of the chargeback process — from dispute analysis to documentation generation, deadline monitoring, fraud detection, and beyond.
  • Your main focus will be to build smart, scalable solutions using Python and AI tools (ML models, LLMs, etc.), always aligned with the evolving rules from Visa, Mastercard, Elo, and Amex.


    • What You'll Be Doing
  • Learn and master chargeback rules across acquiring and issuing operations (we’ll teach you)
  • Work closely with developers to automate manual processes using Python
  • Design and test automations powered by machine learning and generative AI
  • Stay up to date with card network (Visa, Mastercard, Elo, Amex) changes and ensure operational compliance
  • Help translate business rules and customer needs into data-driven, scalable solutions
  • Investigate dispute and fraud patterns using analytics and classification models
  • Build or improve internal tools that boost productivity and recovery efficiency


    • What You Need To Succeed
  • Basic knowledge of Python and interest in applying it to real-world problems
  • Interest or experience with AI tools: LLMs (e.g. OpenAI), ML models, classification, NLP, etc.
  • Analytical and problem-solving mindset
  • Eagerness to learn about chargeback operations and payment networks
  • Strong communication skills and team collaboration
  • Proactive and curious — you ask “why” and seek patterns
  • Ability to understand and act on network updates and deadlines


    • Join us at CloudWalk, where we’re not just engineering solutions; we’re building a smarter, AI-driven future for payments—together.
