ROLE OVERVIEW 

Welocalize is looking for a native-level Spanish (LATAM) 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.
