Welo Global

9d • Onsite

About The Position

Welocalize is seeking a native-level or fully bilingual UK English speaker for a confidential, large-scale AI and consumer technology programme for a global technology and communications client. This hands-on role combines linguistic evaluation of a pre-release AI model with functional testing on client-supplied devices, including a smartphone and next-generation smart glasses. The evaluator will assess the model’s UK English output and test the localized product experience, reporting issues and verifying fixes. The work takes place on-site in a private, secure area of a Welocalize office; remote or work-from-home arrangements are not possible for this programme. The role may also support other linguistic projects as needed. The successful candidate will work alongside an experienced linguist and tester on technology that is not yet publicly available.

Requirements

• Native-level or fully bilingual UK English, written and spoken, with current familiarity with everyday and technical usage.
• Confidence using smartphones and laptops, and comfort moving between iOS and Android.
• Strong attention to detail and fair, objective judgment when assessing quality.
• Ability to work independently, follow detailed test scripts and guidelines, and explain issues clearly in English.

Nice To Haves

• Previous experience in software or app testing, localization quality assurance, or linguistic evaluation.

Responsibilities

• Evaluate pre-release AI model responses in UK English for accuracy, naturalness, appropriateness, and overall quality, including fact-checking responses against source material.
• Compare the UK English experience with the English experience, verify feature parity, complete a user journey using non-English input, and test handling of non-Latin scripts, diacritics, right-to-left text, and mixed-language input.
• Identify display issues and localization errors, including text truncation, overflow, poor rendering, and incorrect dates, numbers, currencies, units, or untranslated strings.
• Document issues so developers can reproduce them, including the steps taken, device and operating system, locale, build ID, and supporting evidence.
• Retest reported issues after fixes are implemented to confirm they are resolved.
• Provide native-speaker feedback 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.
