Czech Linguistic Expert at Mercor

Czech Linguistic Expert | $40/hr | Remote | Part Time

Mercor is hiring Czech linguistic experts for a part-time, remote AI research project run in partnership with a leading research lab. The work centers on evaluating how well a large language model (LLM) performs on Czech-language tasks and on curating high-quality Czech linguistic data to train and improve the model's understanding and generation capabilities.

What the work involves

• Evaluating the quality and accuracy of LLM-generated Czech text across use cases such as translation, summarization, dialogue, and grammar correction.
• Editing, refining, or rewriting Czech content to meet linguistic and cultural standards for Czech-speaking audiences.
• Annotating Czech text for grammatical, syntactic, and semantic features.
• Identifying model errors and language gaps, and collaborating with AI researchers to improve LLM performance.
• Providing detailed linguistic feedback and analysis to guide ongoing model training.

Who it's for

• Native or near-native fluency in Czech, with strong command of grammar, syntax, and stylistics.
• Professional experience in translation, editing, linguistic annotation, or NLP data work in Czech.
• Understanding of Czech nuances, regional variations, register, and context-appropriate usage.
• Professional fluency in English.
• Interest in AI and LLM-driven language technologies (preferred but not required).
• Attention to detail, including spotting subtle errors or unnatural phrasing.
• Clear communication skills and experience working in distributed, remote teams.
