Job description

In Short

MSQ DX Americas is searching for a Senior Quality Assurance (QA) Engineer to join our successful and growing team. This role reports directly to the QA Director and serves as a leader among the QA team, bringing a strong background in both manual and automated testing along with a comfort working with AI-assisted testing and productivity tools. The Senior QA Engineer will be embedded in project teams throughout the delivery lifecycle — sometimes providing QA strategy oversight and direction, and other times serving as the primary hands-on QA engineer on a project. Beyond project work, this person partners continuously with the QA Director to evaluate and shape new processes, procedures, and tools for the broader QA practice.

What You'll Be Doing

The Senior QA Engineer blends hands-on testing execution with team leadership and practice-level influence. Depending on the engagement, this person may act as embedded QA oversight — setting test strategy and direction for a project team — or as the primary QA engineer executing day-to-day testing, or both across a portfolio of projects. This role is responsible for Quality Assurance Testing, guiding clients through the User Acceptance Testing process, and playing an integral role in the coordination of releases across product categories, including feature updates, bug fixes, enhancements, and other changes introduced to the product line. This role also owns quality review of applications, including test plans, test strategy, and test cases developed in partnership with developers, business analysts, and project managers to shape and verify code and confirm conformance to business and system requirements. The role relies on a combination of manual testing and test automation and is expected to bring judgment on where and how to apply AI tools to strengthen QA efficiency and coverage. As
