Qualifications 7+ years of experience in quality assurance or software testing, preferably within agile or scrum environments. Strong understanding of frontend architectures (React, Next.js, or similar). Experience testing RESTful APIs, CMS integrations, or decoupled web applications. Proficiency with modern testing frameworks and tools (e.g., Cypress, Playwright, Postman, Jest). Familiarity with design systems and component-based testing (Storybook or similar).
