Welo Global is a language and data services company that supplies localisation, translation and training data to technology firms, life sciences companies and enterprises expanding internationally. Its work covers translation and multilingual quality assurance, localisation testing for games and software, data annotation and collection across many languages, and the human evaluation and preference work used to improve large language models. The company recruits linguists, annotators and subject-matter reviewers across dozens of languages, which is why it advertises a very high volume of part-time and contract roles tied to specific language pairs.

ROLE OVERVIEW

Welocalize is looking for a native-level Korean speaker to join a large-scale AI and consumer technology programme.

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 Korean, 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 Korean 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.

  • Test the Korean 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.

JOB REQUIREMENTS

  • Native-level or fully bilingual Korean, written and spoken, with a current feel for how the language is really used day-to-day - every day and technical.

  • Confidence with a smartphone and a laptop, and comfort moving 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 the language skill and the attention to detail.

Welocalize helps the world's leading brands speak to a global audience - and language testing sits at the heart of that. You'll work alongside an experienced linguist and tester on technology most people won't see for months, in a team that takes quality and precision seriously.

If you're a native-level Korean speaker with an eye for detail and an interest in how language and technology meet, we'd like to hear from you.
