QA Engineer (m/f/d)

Your Tasks:

• Full-lifecycle involvement: Participate in grooming, design reviews and definition of acceptance criteria (BDD/Gherkin).


• Test assets ownership: Create, update and maintain the test suite covering squad products (mobile, web, API, data flows).


• Code tests that test software: Build maintainable test code, helpers and fixtures; contribute to shared testing libraries/frameworks.


• Functional testing: Compose, execute and assess results of tests according to the agreed Test Strategy (manual where it adds value, automated by default).


• API & contract testing: Validate REST/GraphQL contracts and integrations (e.g., consumer-driven contract tests).


• Non-functional testing: Execute performance, reliability, security (baseline) and accessibility checks where relevant.


• Data-driven QA: Provide and track squad QA metrics (e.g., defect escape rate, flaky test rate, coverage trends, MTTR, lead time to detect).


• Environment readiness: Collaborate on test data management, synthetic users and stable environments (containers/Kubernetes).


• Quality advocacy: Spread a culture of quality, facilitate bug bashes/exploratory sessions, and coach teammates on testing good practices.


• Release readiness: Contribute to go/no-go criteria, risk assessment and post-release validation.

Your profile:

• Automation: Hands-on building UI and API automated tests (mobile and/or web) integrated into CI pipelines.


• Agile delivery: Experience working within cross-functional agile teams.


• BDD: Practical knowledge of BDD (Gherkin) and collaboration around acceptance criteria.


• Mobile Frontend: Proven experience testing mobile apps (Android and/or iOS), including real devices/emulators/simulators.


• API Testing: Strong experience testing REST/GraphQL services (functional and negative scenarios).


• Programming: Experience coding tests and tools in Python (or similar: TypeScript/C#).


• CI/CD: Experience in CI environments (e.g., Azure DevOps, GitHub Actions), including parallelization and flaky-test control.


• Cloud & containers: Familiarity with Azure and/or Google Cloud, Docker/Kubernetes test environments.


• Frontend testing: Experience with modern web stacks (React/React Native) and tools (Playwright/Maestro/Cypress/Appium/Detox).


• The following skills would be a plus: Performance testing (e.g., k6/JMeter), baseline security (e.g., OWASP ZAP), accessibility (WCAG/axe) are a plus!


• Telco Domain Knowledge: Previous engineering experience within an MVNO / MVNE will be a plus
