English Language and Literature Expert

Mercor is seeking experienced English Linguistic Experts to join a cutting-edge AI research project in partnership with a leading research lab. This role centers on evaluating how effectively a large language model (LLM) performs in English-language tasks and on curating high-quality English linguistic data to train and improve the model’s understanding and generation capabilities.

Key Responsibilities:

• Evaluate the quality and accuracy of LLM-generated English text across various use cases (e.g., summarization, dialogue, grammar correction, rewriting, and reasoning).
• Edit, refine, or rewrite English content to meet high linguistic, stylistic, and cultural standards.
• Annotate English text for grammatical, syntactic, semantic, and stylistic features.
• Identify model errors, inconsistencies, and language gaps, and provide feedback to improve LLM performance.
• Provide detailed linguistic feedback and analysis to guide ongoing model training efforts.

You’re a strong fit if you have:

• Native or near-native fluency in English, with an excellent command of grammar, syntax, vocabulary, and stylistics.
• Professional experience in editing, proofreading, writing, linguistic annotation, language evaluation, or NLP data work in English.
• Strong understanding of linguistic nuances, regional variations, tone, and context-appropriate English usage.
• Excellent ability to identify subtle grammatical errors, awkward phrasing, ambiguity, and unnatural language.
• Interest in AI and LLM-driven language technologies is preferred but not required.
• Strong attention to detail, analytical judgment, and written communication skills.
• Ability to work independently in a distributed, remote environment.

Why Join

• Contribute to cutting-edge AI research in partnership with a leading research lab.
• Work on high-impact projects that directly support the development of advanced AI systems.
• Gain hands-on exposure to state-of-the-art AI research and development.
• Work fully remotely with flexible, asynchronous hours.
