• Cover functional, negative, contract and regression scenarios, including auth and error handling
• Keep suites stable and f ast in Jenkins CI, report through Allure, and investigate failures to the root cause

• Work inside a dev team: review API designs and specs, define acceptance criteria, and close coverage gaps
• Mentor other QA engineers and review their code

Requirements

Must have:

• 5+ years in test automation, at least 3 of them writing automation in Python with pytest (fixtures, parametrization, markers, conftest structure)

• Practical experience or solid knowledge of using AI tools in test automation (test generation, code review , debugging, AI agents or MCP)

• Allure reporting, pytest-xdist, Docker
• Performance or load testing (Locust, k6 or similar)
• Basic Playwright or UI automation knowledge
