Sr. Quality Assurance Engineer (REMOTE- US based only)

We are seeking a Sr. Quality Assurance Engineer (REMOTE) for a full time and direct hire role for one of our amazing partners in the United States. This role is remote, but you MUST be living in the United States and be a US Citizen or Green Card Holder. This role does NOT offer sponsorship, it's NOT a consulting role, and we do NOT work with 3rd parties! Overview: We're looking for a highly technical and analytical Senior Quality Assurance Engineer to take ownership of quality across core software applications. You will design, develop, and maintain automated testing frameworks across backend services, APIs, cloud infrastructure, network integrations, and web applications. You'll play a key role in validating high-volume authentication workflows, third-party integrations, data pipelines, and overall system performance. You will work closely with engineering and technology leadership to identify potential issues early, improve test coverage, reduce defects, and help ensure reliable software releases. You will be responsible for developing comprehensive automated and manual testing strategies that ensure reliable, scalable, and secure software. This role goes beyond traditional black-box testing. You'll need to understand the underlying application and cloud infrastructure, work comfortably with APIs and databases, troubleshoot complex issues, and use technical data to identify the root cause of defects. This is a fast-moving environment where adaptability, creative problem-solving, and a willingness to use emerging technologies, including AI, are encouraged. We're looking for someone who enjoys finding better ways to test, automate, troubleshoot, and improve software quality. We are looking for someone who is technically curious, highly analytical, and comfortable getting deep into the technology stack. Someone who naturally asks why something failed rather than simply documenting that it failed. You'll thrive in this position if you enjoy solving complex problems,
