It's a hands-on, on-site role that combines two things: evaluating a pre-release AI model in Spanish (Spain), and testing how the product actually performs on a client-supplied device — a smartphone and a next-generation smart glass. If you enjoy noticing the detail other people miss, this is work you'll find satisfying. MAIN RESPONSIBILITIES Review pre-release AI model outputs inSpanish (Spain) and evaluate them for accuracy, naturalness, appropriateness, and overall quality—would a native speaker say it this way? Fact-check each response against the provided source material.
