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 your language, 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.

It's a hands-on, on-site role that combines two things: evaluating a pre-release AI model in your language, and testing how it performs on a real device. You'll be among the first people to see this technology in Dutch, and your judgement shapes how well it works before anyone else uses it.
If you enjoy noticing the detail other people miss, this is work you'll find satisfying.
MAIN RESPONSIBILITIES
Review pre-release AI model output in Dutch and judge it on accuracy, naturalness, appropriateness, and overall quality — would a native speaker really say it this way? This includes fact-checking each response against the source material.
