Overview

Mercor seeks Spanish language specialists for a part-time AI research project tied to a major research lab. The work centers on testing how well a large language model handles Spanish tasks, from translation and summarization to dialogue and grammar correction. You will also shape training data by editing, rewriting, and annotating Spanish text for grammar, syntax, and meaning. Researchers rely on your notes to spot model gaps and guide the next round of training.

What You'll Do6

  • Review Spanish output from an LLM across translation, summarization, dialogue, and grammar correction tasks.
  • Edit or rewrite Spanish passages so they match linguistic and cultural standards.
  • Tag Spanish text for grammar, syntax, and meaning features.
  • Log model errors and language gaps with clear examples.
  • Share linguistic analysis with AI researchers to steer model training.
  • Provide detailed feedback on unnatural phrasing and subtle mistakes.

Requirements6

  • Native or near-native Spanish fluency with strong command of grammar, syntax, and style.
  • Professional background in Spanish translation, editing, linguistic annotation, or NLP data work.
  • Familiarity with regional Spanish variants and context-appropriate usage.
  • Keen eye for detail and subtle errors or unnatural phrasing.
  • Comfort with remote, distributed teamwork and written communication.
  • Interest in AI and LLM language technology helps but is not required.

Who Should Apply

Spanish language professionals with translation, editing, or annotation experience fit best. The role suits someone who can spot subtle grammar and style issues and explain them to AI researchers. Prior NLP data work or LLM exposure adds weight, but the source treats AI interest as optional.

Salary Insight

The posting lists $50.00/hr for this part-time engagement. That rate sits in the upper range for Spanish linguistic annotation and evaluation work and matches candidates who bring professional translation, editing, or NLP data experience.
