About the Role

We are seeking a Senior QA Engineer who not only brings strong technical expertise in test automation and quality assurance but also excels in communication, collaboration, and balancing priorities. This is a fast-paced team, and success in this role requires the ability to quickly understand complex technical systems, communicate effectively, and partner closely with senior and principal engineers.

The ideal candidate has hands-on experience with API testing, UI testing, and automation frameworks (Playwright preferred). Just as importantly, they can adapt under pressure, prioritize effectively in a dynamic environment, and contribute to a culture of quality, ownership, and teamwork.
