Toptal: 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. 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.
