Bilingual Japanese STEM Expert (PhD) — AI Safety | $68-$72/hr Remote

68–72/hr
Remote · Remote — East Asia preferred
Posted September 4, 2026
part-time

Overview

This contract taps PhD-level scientists who are fluent in both English and Japanese. You will apply your expertise in fields like chemistry, biology, or radiological sciences to test how AI assistants handle specialized technical content. Mercor provides the training on prompt writing and evaluation, so previous AI experience is not necessary. The work is fully remote, starts right away, and candidates in Japan or East Asia are especially encouraged.

What You'll Do4

  • 1Draft sophisticated Japanese-language prompts that span your scientific specialty, from chemical synthesis to molecular biology.
  • 2Analyze AI outputs for scientific accuracy, helpfulness, and adherence to safety policies, then record your ratings.
  • 3Use the provided taxonomy to label prompts and full conversation threads according to content and risk level.
  • 4Complete the initial training on Mercor's evaluation workflow and participate in calibration exercises.

Requirements5

  • 1Earned a PhD, or be actively enrolled in one, in chemistry, biology, or a closely related scientific field.
  • 2Speak and write Japanese at a native or near-native level, and communicate effectively in business-level English.
  • 3Show hands-on proficiency with modern laboratory or computational tools used in your subfield, such as spectroscopy, sequencing, or molecular modeling.
  • 4Demonstrate sound judgment about scientific safety, especially concerning the responsible use of dual-use information.
  • 5Possess deep expertise in a specific domain like organic synthesis, microbiology, virology, genetics, or radiochemistry, which can be highlighted during the screening.

Who Should Apply

This role suits a PhD scientist who enjoys scrutinizing content for accuracy and safety rather than conducting primary research. If you prefer exploring new hypotheses over following strict annotation rules, you might find it constraining. Candidates often miss out when their Japanese is fluent but their written English lacks clarity, or when they claim broad knowledge without a deep niche. Highlighting a specific example where you grappled with safety implications of your work can set you apart.

Salary Insight

The pay is clearly set at $68-$72 per hour, a rate that matches the PhD-level expertise required. For a part-time remote contract, this is above the typical range for scientific annotation work, reflecting the specialized language skills and advanced degree.
