Qualifications

• Bachelor's degree or higher in Linguistics, Czech Language, Czech Literature, English Literature, Communications, Journalism, Translation, or a related field, or equivalent professional experience.
• Native or near-native Czech proficiency, with strong reading and writing skills required.
• Strong professional proficiency in English, minimum C1, to follow guidelines and provide detailed feedback in English.
• 3+ years of professional experience in writing, editing, localization, translation, content QA, journalism, education, or related language-focused work.
• Deep understanding of Czech grammar, spelling conventions, punctuation, diacritics, cases, declension, conjugation, aspect, word order, tone, and style—able to explain why something is wrong and how to fix it.
• Comfortable handling multiple registers, including formal, neutral, conversational, professional, educational, and public-facing Czech, depending on audience and project requirements.
• High attention to detail when spotting subtle meaning shifts, awkward literal translations, incorrect case endings, agreement errors, hallucinated claims, Slovak- or English-influenced phrasing, or culturally mismatched wording.
• Reliable, self-directed, and able to deliver consistent quality in an hourly, remote contractor workflow across time zones.
• Prior experience with AI data training/annotation, translation QA, editorial QA, localization QA, or rubric-based evaluation is strongly preferred.

Responsibilities

• Develop AI Training Content: Create prompts and gold-standard Czech answers across multiple domains, including general knowledge, customer support, education, conversational writing, translation, localization, and culturally sensitive content.
• Optimize AI Performance: Evaluate and rank AI outputs to improve fluency, correctness, tone match, register consistency, meaning preservation, terminology quality, and cultural appropriateness.
• Ensure Model Integrity: Detect unsafe or misleading content, factual hallucinations, bias, mistranslations, ambiguity, policy-risk language, and culturally inappropriate phrasing; validate reliability across use cases.
