This position is listed on behalf of a partner company, who manages all applications and next steps. Our partner is looking for a Staff Quality Assurance Engineer based in United States. This is a high-impact staff-level engineering role focused on elevating quality across a modern, distributed SaaS product environment. You will own automated testing strategy and frameworks across multiple product teams and critical customer journeys. The role combines hands-on coding, test architecture, quality enablement, and cross-functional technical leadership. You will help shift quality ownership directly into engineering while building reliable, measurable testing practices. A major focus will be using AI, APIs, and MCP-based tooling to make complex testing faster and more repeatable. You will influence engineering practices across teams without acting as a manual testing gatekeeper. This is an opportunity to shape a quality engineering practice from the ground up and deliver measurable improvements in product reliability.
