QA Engineer (Remote)

This is a remote position.

MTechZilla is a custom software development agency founded in 2021, serving startups and businesses globally. We specialize in building scalable, production-ready solutions using modern technologies. With a team of 30+ professionals, we've successfully delivered 40+ products.

We're seeking a QA Engineer to own quality across our client engagements - web apps, mobile apps, and backend services built on Next.js, React Native, Node.js, Dot Net, and AWS. You'll work directly within engineering pods, embedded with our clients' product teams, ensuring every release is stable, performant, and production-ready.

This role involves both manual testing, close collaboration with developers and client stakeholders, and using AI-augmented tools to test faster without cutting corners on coverage.

• Design and execute test plans, test cases, and test scripts for web and mobile applications
  

• Perform functional, regression, integration, API, and exploratory testing across multiple client projects
  

• Validate responsive UI behavior across browsers, devices, and screen sizes
  

• Test authentication flows, role-based access, and data integrity across features
  
  

• Identify, document, and track defects with clear reproduction steps, severity, and priority
  

• Work closely with developers to verify fixes and prevent regressions
  

• Maintain test documentation, coverage reports, and release sign-off checklists
  
  

• Use AI tools (e.g., Claude Code, Claude-based test generation) to accelerate test case creation, edge-case discovery, and script maintenance
  

• Apply judgment on when AI-generated tests need human review to ensure real coverage, not just surface-level checks
