• Experience building testing tools, platforms, or quality infrastructure

Ideal Candidate Profile

Background:

• Cross-platform understanding: Understands Web/App architecture, including front-end/back-end interaction, network requests, cache mechanisms, and WebView

• UX sensitivity: Can identify experience issues from the user's perspective, not just whether functionality works

• Test tooling: Experience building test platforms, tools, or quality infrastructure

• Collaboration drive: Can push developers to fix issues rather than passively waiting

Soft Skills:

• Rigorous and detail-oriented

• "Destructive thinking" mindset — adept at finding system weaknesses

• Quality ownership mentality — treats quality as personal responsibility

Bonus Points

• Payment, transaction, or financial system QA experience
