FULL DESCRIPTION

We’re looking for a Senior Test Engineer to lead quality assurance across Vintage Cash Cow's customer-facing websites and front-end applications and mentor a team of testers. This isn’t just about finding bugs—it’s about building a culture of quality from the ground up. You’ll be designing and implementing automated test frameworks using Playwright and C#, guiding manual testing efforts, and ensuring our customers receive reliable, polished experiences every time.

Key Responsibilities

  • Design, build, and maintain automated test suites using Playwright and C#.
  • Test front-end web applications across our brand portfolio, ensuring consistent quality and user experience.
  • Own the test automation framework end-to-end: from strategy and implementation to CI/CD integration.
  • Write clean, maintainable test code following best practices and modern patterns.

Manual Testing & Quality Assurance

  • Plan and execute manual testing for new features, regression, and exploratory testing.
  • Create and maintain test plans, test cases, and defect reports with clear documentation.
  • Work closely with developers to identify root causes and verify fixes.

Collaboration & Process

  • Partner with product managers and developers to understand requirements and define acceptance criteria.
  • Participate in sprint planning, stand-ups, and retrospectives as a quality advocate.
  • Provide clear release readiness assessments and risk analysis.
  • Integrate automated tests into CI/CD pipelines (Azure DevOps, GitHub Actions).

Team Leadership & Growth

  • Manage and mentor junior testers, supporting their growth in both manual and automation skills.
  • Conduct test reviews and pair-testing sessions to share knowledge and improve quality.
  • Champion testing best practices and advocate for quality across the engineering team.

Innovation & Continuous Improvement

  • Stay current with testing tools, frameworks, and methodologies, recommending improvements.
  • Propose and lead initiatives to improve test coverage, speed, and reliability.
  • Own and evolve testing standards and processes to drive continuous improvement.
