Remote Bilingual Simplified Chinese STEM Expert - AI Trainer

Mercor is looking for a Bilingual Simplified Chinese STEM Expert with experience in biology / physics / chemistry theory and problem-solving to develop and refine high-quality reasoning questions that evaluate AI models. Your knowledge in biology / physics / chemistry will ensure the accuracy, rigor, and instructional quality of these test items. You will create and evaluate Simplified Chinese / English prompts and responses, ensuring scientific precision while maintaining clear, natural Simplified Chinese phrasing and alignment with English where needed.

• Design and Optimize STEM-Based Prompts (Bilingual):
  Create detailed prompts in Simplified Chinese and / or English with multiple constraints and scientific instructions.
• Define and Document Evaluation Standards:
  Establish high-level expectations for correct responses in STEM contexts, and develop comprehensive rubrics that account for scientific rigor and—when in Simplified Chinese—linguistic clarity and appropriate academic tone.
• Conduct Model Testing and Grading (Bilingual):
  Run prompts through models and assess preliminary outputs against expectations for scientific accuracy, reasoning quality, and clarity, comparing Simplified Chinese vs. English where needed.
• Support Benchmarking and Quality Assurance:
  Collaborate in QA review processes to ensure prompt tasks and rubrics meet scientific rigor, maintaining consistency and reliability across Simplified Chinese-language benchmarks before integration into official benchmarks.

• Native-level fluency in Simplified Chinese (written) with strong reading / writing ability in English.
• BS or BA in Biology / Physics / Chemistry.
• Familiarity with undergraduate-level biology / physics / chemistry topics.
• Strong writing and critical thinking skills.
• Ability to work independently and meet deadlines.

• 2+ years of experience in teaching, research, or an applied STEM discipline field.

• Complete an AI-led interview (around 15 minutes).
• If approved, complete a paid assessment focused on writing and rubric creation.
• Then, if selected, you will be invited to work on the project.

• Expect to contribute at least 20 hours per week.
• Expect a commitment of around 1 month.
• You’ll be working in a structured project environment with clear goals and tools.
