Requirements:

• Significant experience as a Senior Manual QA Engineer, specializing in complex, large-scale enterprise systems.
• Proven, expert-level experience in creating complete manual test suites from scratch for legacy applications with little to no existing documentation.
• Exceptional ability to interview non-technical stakeholders (SMEs) and translate their business knowledge into precise, testable user flows and test cases.
• Mastery of all manual testing methodologies: regression, integration, component, functional, and end-to-end testing.
• Experience in leading or mentoring junior or middle QA engineers.
• Experience testing applications undergoing major technical migrations (.NET, Angular, or similar) is a significant advantage.

• Collaborate intensively with client-side Subject Matter Experts (SMEs) to reverse-engineer, map, and document all critical user workflows and business processes.
• Establish this new test suite as the project's "single source of truth" for all application functionality, forming the baseline for all future testing.
• Mentor and lead the Middle QA Engineer, delegating test case creation and execution to ensure full test coverage.
• Design and execute continuous in-sprint testing (component and integration) as new, modernized pieces are delivered by the development teams.
• Lead the full-stack, end-to-end regression cycles at major project milestones to validate the fully integrated application against the baselines you created.
• Facilitate User Acceptance Testing (UAT) sessions with client SMEs to achieve final business sign-off before deployment.
• Act as the primary QA voice, expertly identifying, documenting, and triaging defects and providing clear, actionable feedback to the development teams.

We offer*:
