Job description

This is a hands-on, manual QA-first role in a fast-moving environment where features ship often, experiments run continuously, and quality cannot be an afterthought. You'll work closely with Product and Engineering to ensure that what reaches users is stable, reliable, and works as expected across browsers, devices, and real-world scenarios.

We're not looking for someone who only executes test cases. We're looking for a quality owner - someone who thinks in user journeys, spots risks early, understands how systems break in production, and proactively raises issues before they impact customers.

Testing & QA Approach

  • Ability to think in real user scenarios, not just happy paths.
  • Strong regression mindset - ability to identify areas that break repeatedly.
  • Comfortable testing partially implemented or fast-changing features.
  • Able to validate fixes independently, without relying on step-by-step instructions.
  • Consistent focus on quality across environments and releases.

Technical Awareness (Non-Coding)

  • Ability to read and understand API responses (REST / JSON).
  • Familiarity with HTTP status codes and common error types.
  • Awareness of common frontend and deployment-related issues, including:
  • Cache invalidation problems
  • Chunk loading failures
  • Environment mismatches after deploys

Work Style & Collaboration

  • Clear, structured written communication of bugs and findings.
  • Ability to describe issues using:
  • Steps to reproduce
  • Expected vs actual behavior
  • Proactive mindset - flags risks and potential issues early.
  • Comfortable working directly with developers and product managers.
  • Takes ownership of quality, not just test execution., * Experience with D2C SaaS products.
