Portuguese Brazilian Linguistic Evaluator & Functional Tester

ROLE OVERVIEW 

Welocalize is looking for a native-level Portuguese Brazilian 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. 

Welocalize is looking for a native-level Portuguese Brazilian 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 Portuguese Brazilian , 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 Portuguese Brazilian 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 Portuguese Brazilian 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 Portuguese Brazilian, 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 Portuguese Brazilianspeaker with an eye for detail and an interest in how language and technology meet, we'd like to hear from you.
