QA Engineer (m/f/d) (Barcelona, ES) bei Jobs & Karriere bei Schwarz Corporate Solutions

Your Tasks

• Quality Strategy: Define and evolve the squad’s test strategy (unit, integration, contract, E2E, exploratory, non-functional) aligned with the test pyramid.
• Automation First: Design, implement and maintain automated tests for mobile, web and APIs as part of CI/CD.
• Collaboration: Work closely with developers, designers and product owners to prevent defects early (“shift-left”) and validate in production (“shift-right”).çObservability & Metrics:
• Establish quality KPIs and dashboards, using data to drive improvements and release decisions.
• Continuous Improvement: Propose ideas and processes that raise the bar on reliability, performance and usability.
• 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 andpost-release validation.
