Senior QA Engineer (Mobile and Web)

This position is posted by Jobgether on behalf of a partner company. We are currently looking for a Senior QA Engineer (Mobile and Web) in Brazil.

This role is designed for a seasoned QA professional who thrives in fast-moving, product-driven environments where quality is embedded throughout the development lifecycle rather than validated at the end. You will work on web and mobile applications that are often in active evolution, collaborating closely with product managers, designers, and engineers to define what “good” truly means from both a user and business perspective. The role requires strong ownership of testing strategy, including exploratory, regression, and end-to-end testing across multiple platforms. You will play a key part in ensuring product reliability, usability, and performance while contributing to shaping testing approaches in dynamic, international project teams. This is a contractor-based opportunity ideal for professionals who enjoy ambiguity, collaboration, and high-impact digital products.
