Senior Quality Engineer — Chromium Browser Extensions & Ecommerce |

Headquarters: Remote
URL: https://www.toptal.com/

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
