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
