Middle QA Mobile Full-stack Engineer

Product: BOSS Revolution: Calling App The mobile application, which includes International Calling, Mobile Top-up, and Money Transfer services, supports IDT's mission of enabling people to keep in touch and share resources with family and friends worldwide. As middle QA you will be working with cross-functional global teams to support different parts of the product: First, the voice assistant. This isn't standard UI automation. The output is non-deterministic, the input is speech with heavy accents and background noise, and the result is a financial transaction. You'll design how we measure intent recognition quality, how we catch a model that silently changes behaviour after a prompt or version update, and how we prove the transfer went to the right recipient for the right amount. Then, backend automation across the company. Internal teams need automated services and tooling that don't exist yet. You'll build and own that layer, so your work gets used daily by people outside your own team.
