Description

We are seeking a native-level Vietnamese speaker to join a confidential, large-scale AI and consumer technology programme for a major global technology and communications client. You will evaluate a pre-release AI model in Vietnamese and test its performance on a client-supplied device, including a smartphone and next-generation smart glass.

Main Responsibilities:

  • Review pre-release AI model output in Vietnamese, assessing accuracy, naturalness, appropriateness, and overall quality.
  • Test the Vietnamese experience against the English one, confirming feature parity and checking for localization errors.
  • Identify display problems and write clear reports for developers to reproduce issues.
  • Share your perspective as a native-level speaker on navigation, usability, and language-specific nuances.
  • Work on-site in a private, secure area of the Welocalize office.
  • Support other linguistic projects as needed.

Job Requirements:

  • Native-level or fully bilingual Vietnamese, written and spoken.
  • Confidence with smartphones and laptops, comfortable moving between iOS and Android.
  • Sharp eye for detail and fair, objective judgement when assessing quality.
  • Ability to work independently, follow detailed test scripts, and explain issues clearly in English.
  • Previous experience in software or app testing, localization QA, or linguistic evaluation is a strong plus.
