Senior Mobile QA Automation Engineer

About the project

A trading exchange platform with a mobile application for iOS and Android, built with React Native. The product is actively growing, and the team is now investing in quality at the mobile level. There is currently no automated test coverage and no test stack has been chosen yet, so you will build mobile automation from scratch, including selecting the tools and approach. You will be the first automation engineer on the mobile side.
