About the Role

In this hourly, remote contract role with flexible scheduling, you will perform linguistic quality assurance and fact-checking on Catalan content, applying rubrics and a structured error taxonomy so that language quality is judged consistently and reproducibly.

You will review AI-generated responses in Catalan and English, evaluate reasoning quality and step-by-step problem-solving, and provide expert feedback that helps models produce accurate, logical, and clearly explained answers. You will assess solutions for accuracy, clarity, and adherence to the prompt; identify errors in methodology or conceptual understanding; fact-check information; write high-quality explanations and model solutions; and rate and compare multiple AI responses.

What You'll Do

• Perform Linguistic Quality Assurance: Review Catalan text for grammar, orthography, punctuation, and register using a consistent error taxonomy and rubric-based scoring.
• Fact-Check Content: Verify Catalan-language responses against reliable references and flag unverifiable, misleading, or internally inconsistent claims.
• Enforce Locale and Style Consistency: Apply Catalan locale, register, and style-guide rules (for example Central vs Valencian conventions, formal vs informal address) within each task or project guideline.
• Document Your Judgments: Record review decisions and escalation notes in clear, professional English (C1+) so others can reproduce your reasoning.
• Optimize AI Performance: Evaluate and rank AI responses to improve the model's accuracy, fluency, and contextual relevance.
• Ensure Model Integrity: Test AI outputs for potential inaccuracies or biases, validating their reliability across use cases.

What You Bring

• At least 1 year of relevant professional experience in Catalan language work: editing, translation, localization, linguistic QA, content review, or similar.
• Native or near-native written Catalan (C2) with strong command of normative grammar, orthography, punctuation, and register.
• Bachelor's degree in Linguistics, Translation and Interpreting, Catalan Philology, Journalism, or equivalent practical experience.
• English proficiency: minimum C1 level.
• Fact-checking capability: able to verify claims using reputable sources, resolve ambiguities, and document evidence succinctly.
• Linguistic quality assurance experience: applying rubrics and rating scales, consistency checks, and structured error categorization for language quality.
• Previous experience with AI data training, annotation, or evaluating AI-generated content is strongly preferred.
• Able to work independently as a remote contractor: detail-oriented, self-directed, dependable turnaround, and careful handling of confidential project content.
