About the Role
We're looking for an experienced Quality Engineer to test ecommerce and web experiences, with a strong emphasis on Chromium-based browser extensions (Chrome, Edge). 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.
What You'll Do


Create test plans and test cases from product requirements and designs


Perform manual testing of ecommerce and web experiences, with a focus on Chromium-based browser extensions (Chrome, Edge)


Conduct exploratory, regression, and end-to-end testing


Report defects with clear reproduction steps and supporting evidence


Investigate issues using browser dev tools, logs, HAR files, and network traces


Maintain test cases and regression suites in a test management tool (e.g., Qase)


Build and maintain Playwright tests in Python or TypeScript


Work within existing automation frameworks and CI pipelines


Collaborate closely with engineering and product teams, communicating results, blockers, and risks clearly


What You Bring


Hands-on Chromium browser extension testing experience (Chrome and/or Edge) — required


5+ years of software testing experience


Strong manual testing and defect investigation skills, including test plan and test case creation


Hands-on experience with Playwright (Python or TypeScript)


Strong understanding of browser behavior and web technologies, including browser dev tools and network debugging


Experience with Jira or similar test management and issue tracking tools


Experience working within CI pipelines and existing automation frameworks


Ability to work onsite five days per week


Nice to Have


Safari extension testing experience (support planned but not yet required)


Experience testing ecommerce-specific workflows (checkout, payments, cart logic)


Why This Role


Full-spectrum QE ownership: Blend manual, exploratory, and automated testing rather than being siloed into one


Real technical depth: Root-cause issues using dev tools, HAR files, and network traces, not just log defects


Established foundation: Work within existing CI/automation pipelines rather than building from scratch


Direct collaboration: Close partnership with engineering and product teams
