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.

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.
