Catalan Language Expert - Spain

About SME Careers

As AI systems become more sophisticated, they rely on human knowledge to better understand context and the world. SME Careers is 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 Catalan expertise directly helps improve the world's premier AI models by making their Catalan language output more natural, reliable, culturally accurate, and clearly written.

About the Role

In this hourly, remote contract role with flexible scheduling, you will work as a Catalan Language Specialist to create high-quality Catalan reference content and review AI-generated Catalan content, evaluating language quality and step-by-step reasoning while providing precise written feedback.

This role centres on authoring gold-standard Catalan material and judging model output against it. You will assess outputs for accuracy, fluency, grammar, spelling, tone, cultural appropriateness, and adherence to the prompt. You will identify errors in meaning, mistranslation, register (formal vs informal), ambiguity, regional variation, and logical consistency; fact-check claims when needed; write high-quality rewrites and model answers that demonstrate best practices in Catalan writing; and rate and compare multiple AI responses based on correctness and overall quality.

Key Responsibilities

• Develop AI Training Content: Create prompts and gold-standard Catalan answers across multiple domains, including general knowledge, customer support, education, conversational writing, translation, localization, and culturally sensitive content.
• Author Model Answers: Write high-quality rewrites and reference answers that demonstrate best practice in Catalan writing, so models have a clear standard to learn from.
• Optimize AI Performance: Evaluate and rank AI outputs to improve fluency, correctness, tone match, register consistency, meaning preservation, regional appropriateness, and cultural fit.
• Handle Register and Regional Variation: Apply the right conventions across standard Catalan, Valencian, and Balearic usage, and across formal and informal address, depending on project requirements.
• 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.

Your Profile

• Bachelor's degree or higher in Linguistics, Catalan Philology, Catalan Literature, English Literature, Communications, Journalism, Translation, or a related field, or equivalent professional experience.
• Native or near-native Catalan 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 Catalan grammar, spelling conventions, punctuation, accents, pronouns, verb forms, idiomatic usage, tone, and style, and the ability to explain why something is wrong and how to fix it.
• Comfortable handling multiple registers and regional variation, including standard Catalan, Valencian, Balearic usage, formal and informal Catalan, and Spain, Andorra, and diaspora audience expectations, depending on project requirements.
• High attention to detail when spotting subtle meaning shifts, awkward literal translations, false friends, incorrect pronoun usage, hallucinated claims, Castilian-influenced phrasing, or culturally mismatched wording.
• Reliable, self-directed, and able to deliver consistent quality in an hourly, remote contract workflow across time zones.
• Prior experience with AI data training and annotation, translation QA, editorial QA, localization QA, or rubric-based evaluation is strongly preferred.
