• Daily hands-on experience with AI-powered development and QA tools (e.g., Claude Code, Codex) for code exploration, debugging, test generation, and root cause analysis.
• Advanced expertise in browser automation technologies, including Playwright, Puppeteer MCP, or similar debugging tools.
• Ability to independently navigate large React and Next.js codebases, identify testing gaps, and suggest improvements.
• Strong product mindset, able to assess business impact, user experience, and technical risk beyond standard bug reporting.
• Comfortable in fast-paced environments with incomplete specifications, continuous iteration, and shifting priorities.
• Excellent written and verbal communication skills in English.
• Experience with online marketplaces, complex user flows, or consumer-facing platforms is a plus.
