This role blends hands-on manual testing and defect investigation with maintenance of existing Playwright automation — you'll need to be equally comfortable digging into browser dev tools to root-cause an issue and extending an existing test suite. Hands-on Chromium extension testing experience is a must-have for this role, not a nice-to-have. This is an onsite contract engagement, five days per week.</p> <h2>What You'll Do</h2> <ul> <li> <p>Create test plans and test cases from product requirements and designs</p> </li> <li> <p>Perform manual testing of ecommerce and web experiences, with a focus on Chromium-based browser extensions (Chrome, Edge)</p> </li> <li> <p>Conduct exploratory, regression, and end-to-end testing</p> </li> <li> <p>Report defects with clear reproduction steps and supporting evidence</p> </li> <li> <p>Investigate issues using browser dev tools, logs, HAR files, and network traces</p> </li> <li> <p>Maintain test cases and regression suites in a test management tool (e.g., Qase)</p> </li> <li> <p>Build and maintain Playwright tests in Python or TypeScript</p> </li> <li> <p>Work within existing automation frameworks and CI pipelines</p> </li> <li> <p>Collaborate closely with engineering and product teams, communicating results, blockers, and risks clearly</p> </li> </ul> <h2>What You Bring</h2> <ul> <li> <p>Hands-on Chromium browser extension testing experience (Chrome and/or Edge) — required</p> </li> <li> <p>5+ years of software testing experience</p> </li> <li> <p>Strong manual testing and defect investigation skills, including test plan and test case creation</p> </li> <li> <p>Hands-on experience with Playwright (Python or TypeScript)</p> </li> <li> <p>Strong understanding of browser behavior and web technologies, including browser dev tools and network debugging</p> </li> <li> <p>Experience with Jira or similar test management and issue tracking tools</p> </li> <li> <p>Experience working within CI pipelines and existing automation frameworks</p> </li> <li> <p>Ability to work onsite five days per week</p> </li> </ul> <h2>Nice to Have</h2> <ul> <li> <p>Safari extension testing experience (support planned but not yet required)</p> </li> <li> <p>Experience testing ecommerce-specific workflows (checkout, payments, cart logic)</p> </li> </ul> <h2>Why This Role</h2> <ul> <li> <p>Full-spectrum QE ownership: Blend manual, exploratory, and automated testing rather than being siloed into one</p> </li> <li> <p>Real technical depth: Root-cause issues using dev tools, HAR files, and network traces, not just log defects</p> </li> <li> <p>Established foundation: Work within existing CI/automation pipelines rather than building from scratch</p> </li> <li> <p>Direct collaboration: Close partnership with engineering and product teams</p> </li> </ul> <h2>How to Apply</h2> <p>Ready to bring rigorous QE ownership to ecommerce and browser extension testing?
