About Welocalize
ROLE OVERVIEW
Welocalize is looking for a native-level Polish 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.

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 Polish, and your judgement shapes how well it works before anyone else uses it.

MAIN RESPONSIBILITIES
Review pre-release AI model output in Polish 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 Polish 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 Polish, 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 Polish speaker with an eye for detail and an interest in how language and technology meet, we'd like to hear from you.
