  • Regression testing during releases and infrastructure migrations

  • Writing test cases, checklists, and documenting test results

  • Collaborating with developers, product managers, and analysts based on test outcomes

  • Collecting and analyzing QA metrics

  • Opportunity to grow into AQA: automation of card and payment flow testing (API-level)

Requirements and expectations

  • Confident use of Postman (or similar tools)

  • Basic ability to read code (Java / JS / Kotlin)

  • Experience with PostgreSQL: writing queries, validating stored data and entity relations
