Senior QA

About the Role

As a Senior QA Engineer specializing in mobile ecosystems, you will play a critical role in ensuring the quality and performance of native applications for iOS and Android platforms. You will master the complexities of testing real‑device hardware, mobile operating systems, and associated backend integrations. While the focus is on native app, device and API testing, you will also have experience testing web‑based applications and interfaces to assist with overall project deliverables.

You will work across the team with developers, designers, and other QA engineers to understand requirements and validate that features work as expected. Your day‑to‑day will include executing test cases, validating critical user journeys, reporting bugs, performing API testing, and testing LLM‑based functionality within our applications. This role is a unique prospect for a tester who wants to work with cutting‑edge large language models (LLMs).
