What this actually is

You evaluate AI responses in the target language, rate translation quality, write prompts in your native language, and flag errors. Not professional translation work in the traditional sense. The platform title (Thai Linguistic Expert) reflects the rate band and the expertise required, not the day-to-day work.

How Mercor picks people

  1. Upload your CV and answer the role's written questions.
  2. Do a video interview with Mercor's AI interviewer. Most take about 20 minutes, in English unless the role says otherwise.
  3. Some roles add a skills test. A test you pass once counts for similar roles.
  4. The project team reviews your results and sends offers to the people it picks.

Before you start

  • Take Mercor's free practice interview first. It does not count toward any application.
  • Use Chrome on a computer with a camera and microphone, in a quiet room.
  • You can retake an official interview up to 3 times, but hiring teams see how many times you retook it.

Not every applicant gets an offer. Prepare well for the interview.

Original posting from Mercor

Mercor is seeking experienced Thai 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 Thai-language tasks and on curating high-quality Thai linguistic data to train and improve the model's understanding and generation capabilities.

Key Responsibilities:

  • Evaluate the quality and accuracy of LLM-generated Thai text across various use cases (e.g., translation, summarization, dialogue, grammar correction).
  • Edit, refine, or rewrite Thai content to meet linguistic and cultural standards for Thai-speaking audiences.
  • Annotate Thai text for grammatical, syntactic, and semantic features.
  • Identify model errors and language gaps, and collaborate with AI researchers 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 Thai, with excellent command over grammar, syntax, and stylistics.
  • Professional experience in translation, editing, linguistic annotation, or NLP data work in Thai.
  • Strong understanding of Thai nuances, regional variations, register, and context-appropriate usage.
  • Professional fluency in English.
  • Interest in AI and LLM-driven language technologies (preferred but not required).
  • Excellent attention to detail and ability to spot subtle errors or unnatural phrasing.
  • Clear communication skills and experience working in distributed, remote teams.

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.
  • Join a fast-moving project where your expertise and judgment can have a meaningful impact.
