Polish Linguistic Evaluator & Functional Tester

Role Summary

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.

Welocalize is looking for a native-level Polish 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 Polish , 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.

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.

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.
