Traditional Chinese Localization QA Tester

Welo Global; Barcelona; On-site; EUR 48,000 - 60,000; Full time

Job summary

Welocalize is seeking a native-level Traditional Chinese speaker for a confidential, on-site AI and consumer technology programme with a major global client. You will evaluate a pre-release AI model in your language and test how it performs on client devices, shaping product readiness before launch.

You’ll work in a private Welocalize office space, collaborating with an experienced linguist and tester. Remote work isn’t possible for this programme, and attention to detail is essential.

Qualifications

• Native-level Traditional Chinese, written and spoken, with daily feel for how the language is really used — everyday and technical.
• Comfort with a smartphone and a laptop, and ability to move between iOS and Android.
• A sharp eye for detail and fair, objective judgement when assessing quality.
• The ability to work independently, follow a detailed test script and guideline, and explain an issue clearly in English.
• Previous experience in software or app testing, localization QA, or linguistic evaluation is a strong plus — though not essential if you bring language skill and attention to detail.

Responsibilities

• Review pre-release AI model output in Traditional Chinese and judge it on accuracy, naturalness, appropriateness, and overall quality.
• Test the Traditional Chinese experience against the English one: confirm feature parity, complete a full user journey using non-English input, and check the product handles non-Latin script, diacritics, right-to-left text, and mixed-language input correctly.
• Spot any display problem (text cut off, overflowing, or rendering badly) and any localization error — a wrong date, number, currency, unit, or a string left untranslated.
• Write up each issue clearly so a developer can reproduce it: the step taken, the device and operating system, the locale, the build ID, and supporting evidence. Re-test once a fix lands to confirm it’s resolved.
• Share your perspective as a native-level speaker on navigation, usability, and the language-specific nuance only a fluent speaker would catch.
• Work on-site in a private, secure area of the Welocalize office. Because of the confidential, pre-release nature of the technology, a remote or work-from-home arrangement isn’t possible for this programme.
• Support other linguistic projects as needed.
