ROLE OVERVIEW 

Welocalize is looking for a native-level Dutch speaker to join a confidential, large-scale AI and consumer technology programme for a major global technology and communications client. 

It's a hands-on, on-site role that combines two things: evaluating a pre-release AI model in Dutch, 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 inDutch 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. 

Test the Dutch experience against English: confirm feature parity, complete an end-to-end user journey using non-English input, and verify that the product correctly handles non-Latin scripts, diacritics, right-to-left text, and mixed-language input.
