Pay: up to $25/hour
In this hourly, remote contractor role, you will work as a Czech Language Expert (SME) to review AI-generated Czech content and/or create high-quality Czech reference content, evaluating language quality and step-by-step reasoning while providing precise written feedback. You will assess outputs for accuracy, fluency, grammar, spelling, tone, cultural appropriateness, and adherence to the prompt; identify errors in meaning, mistranslation, register, ambiguity, unnatural phrasing, terminology, and logical consistency; fact-check claims when needed; write high-quality rewrites and model answers that demonstrate best practices in Czech writing; and rate and compare multiple AI responses based on correctness and overall quality.
This role is with SME Careers, a fast-growing AI Data Services company and subsidiary of SuperAnnotate, delivering training data for many of the world’s largest AI companies and foundation-model labs. Your Czech expertise directly helps improve the world’s premier AI models by making their Czech language output more natural, reliable, culturally accurate, and clearly written.
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.
Requirements
- 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.
