General QA Engineer

What you will do:

• Work in a cross-functional team with product managers, analysts and developers on a high-load telecom platform

• Own test planning for features: planning, test design, execution, follow-up, and reporting
• Test APIs and integrations across microservices, verifying the full data flow
• Plan and run performance and load tests using JMeter, and analyze results
• Develop automated tests across layers (component, integration, E2E) using Java 21, JUnit 5, REST Assured, Testcontainers, WireMock, and Allure
• Maintain and stabilize existing test suites in CI
• Run regression testing and triage failures
• Maintain test documentation in Jira, Zephyr, and Confluence
