The Role

We are looking for a Senior Quality Assurance Engineer for a project-based assignment to own quality across a React Native mobile application and a Next.js web experience, backed by Java/Spring Boot services behind a Node BFF. We are looking for a senior QA engineer who investigates rather than just reports. The work is hands-on: real devices, developer tools, logs, APIs, and automation, not only clicking through the UI. You will work closely with engineering, product, and design throughout feature development and release cycles. The single most important non-technical trait we are hiring for is clear communication.
