  • Write automated tests using JavaScript, TypeScript, or Python with frameworks like Playwright or Cypress
  • Investigate production issues using logs, network traces, and API responses; reproduce and verify customer-reported bugs
  • Maintain regression coverage and strengthen release quality by partnering with engineers on acceptance criteria

  • Exploratory and functional testing
  • JavaScript, TypeScript, or Python
  • Test automation frameworks (Playwright, Cypress, pytest)
