Spanish Linguistic Expert (Remote, AI Lab Project)
Listing checked September 10, 2026 · pay as published by Mercor
Overview
Mercor is building a Spanish-language dataset and evaluation set for a large language model created with a leading research lab. You will judge model output in tasks such as translation, summarization, dialogue, and grammar correction, then improve Spanish text so it reads as natural and meets cultural expectations. The project also calls for linguistic annotation of grammar, syntax, and meaning, plus written notes that help AI researchers see where the model fails. Work happens remote and pays by the hour, so you can fit the project around other commitments. Your feedback shapes how the model handles Spanish across regions and contexts.
What You'll Do7
- 1Review Spanish text generated by a large language model across translation, summarization, dialogue, and grammar correction tasks, then flag errors in meaning, tone, and usage.
- 2Edit, refine, or rewrite Spanish passages so they meet native-level style, regional preferences, and cultural norms.
- 3Annotate Spanish sentences for grammar, syntax, and meaning, creating clean data for model training.
- 4Track patterns where the model fails, such as gender agreement, false friends, or stiff phrasing, and share those findings with AI researchers.
- 5Write detailed feedback and examples that guide updates to model training and evaluation.
- 6Compare model output with reference translations and style guides to judge accuracy and natural flow.
- 7Work with researchers to test changes and review fresh model output after training runs.
Requirements7
- 1Native or near-native Spanish with strong command of grammar, syntax, and style.
- 2Professional background in translation, editing, linguistic annotation, or NLP data work for Spanish.
- 3Deep understanding of regional variations, register, idiom, and context-appropriate usage.
- 4Interest in AI and LLM language tools, though this is not required.
- 5Sharp eye for subtle errors, unnatural phrasing, and inconsistencies.
- 6Clear written communication and experience with remote, distributed teams.
- 7Ability to explain linguistic choices to non-specialists.
Who Should Apply
The ideal candidate speaks Spanish at a native or near-native level and has professional experience in translation, editing, linguistic annotation, or NLP data work. You can defend grammar and style choices, spot regional differences, and give clear notes on why a model output sounds wrong or unnatural. The role fits people who enjoy close reading of Spanish text and want to support LLM research, even if they have not worked in AI before. Candidates who only use Spanish in casual settings, or who lack formal writing or annotation experience, tend to score low on fit. Applications often get rejected when they show no sample of error analysis or when they cannot explain how they would handle regional variation in model output.
Salary Insight
The project pays $50.00 per hour. For Spanish linguistic annotation and LLM evaluation contracts, this rate sits near the top of common hourly ranges and fits candidates with professional translation or NLP data experience. Entry-level language speakers often see lower offers, so the pay reflects the precision and domain knowledge this work requires.
