What you´ll do
Quality Strategy & Shift-Left Integration- Own the Business Logic: Partner with product owners, functional analysts, QA peers, and developers to dissect workflows, identify edge cases, and challenge assumptions before a single line of code is written.
- Architect the QA Plan: Assess existing coverage and constraints to establish a risk-based strategy encompassing exploratory, integration, and E2E testing.
- Mentor & Elevate the QA Team: Act as the technical anchor for fellow QA engineers. Guide their daily testing efforts, ensure strict alignment with the overarching QA strategy, and continuously upskill the team on modern automation practices.
- Make Quality Visible: Build coverage matrices and dashboards that clearly communicate release confidence, testing gaps, and risks to both technical and business stakeholders.
Hands-On Automation & Engineering- Bridge Cross-Functional Environments: Partner directly with DevOps and Backend QA teams to eliminate environment discrepancies, resolve complex cross-domain test data constraints, and ensure unbroken end-to-end test coverage across the full product stack.
- Build Resilient Automation: Develop and maintain reliable E2E tests using Playwright (TypeScript/JavaScript), alongside targeted API and integration suites. Focus strictly on high-value, repeatable scenarios.
- Co-drive Testability & Best Practices: Modify application components directly to ensure reliable test targeting (e.g., injecting data-testid attributes), and lead technical discussions with the team on how to maximize Playwright’s API capabilities.
- Navigate Enterprise Reality: Design effective testing approaches when test data is scarce, shared, or inconsistent using synthetic data, mocks, and stubs.
- CI/CD & Pipeline Health: Collaborate with the Tech Lead to integrate test execution into CI/CD pipelines, aggressively investigate failures, and eradicate flaky tests.
Continuous Improvement via Telemetry & AI- Leverage Production Data: Use production telemetry (Sentry), reported incidents, and security findings to continuously patch regression gaps and adapt the testing strategy.
- Multiply Impact with AI: Utilize JetBrains AI to accelerate test code development, analyze specifications, and identify missing test scenarios.
