The Role

You will work with content spanning general knowledge, customer support, education, conversational writing, translation, localization, and culturally sensitive topics.

• Estimated project duration of 1–3 months

What You'll Do

You will evaluate Slovenian-language model outputs against detailed quality standards and provide precise written feedback. Your work will help identify both obvious errors and subtle issues that affect meaning, naturalness, and cultural fit.

• Review spelling, grammar, punctuation, diacritics, tone, register, and prompt adherence
• Assess accuracy, fluency, cultural appropriateness, terminology, and reasoning quality
• Identify mistranslations, ambiguity, unnatural phrasing, logical inconsistencies, and factual hallucinations
• Flag bias, unsafe language, and culturally inappropriate content
• Explain errors clearly and recommend how responses should be corrected
• Create prompts, gold-standard Slovenian answers, rewrites, and model answers
• Rate and rank responses for correctness, meaning preservation, terminology quality, register consistency, and overall quality
• Evaluate content across general knowledge, customer support, education, conversational writing, translation, localization, and culturally sensitive subjects

You must have native or near-native Slovenian proficiency and strong professional English proficiency at a minimum C1 level. English is needed to follow evaluation guidelines and provide detailed written feedback.

Deep knowledge of Slovenian grammar and usage is essential, including cases, declension, conjugation, agreement, dual-number usage, word order, tone, and style. You should be able to distinguish formal, neutral, conversational, professional, educational, and public-facing registers.

A bachelor's degree or higher in linguistics, Slovenian language or literature, English literature, communications, journalism, translation, or a related field is required, unless you have equivalent professional experience. At least three years of relevant professional experience is also required.

• Native or near-native Slovenian reading and writing ability

• Relevant language-focused degree or equivalent professional experience
• At least three years of experience in writing, editing, translation, localization, content QA, journalism, education, or related work
