Bilingual Hindi STEM Expert (PhD): AI Safety

What you'll do

India trains a very large number of chemistry and biology PhDs, but almost all of that training happens in English. Writing a precise, natural technical question in Hindi is a different skill from holding the degree, and it is the one this listing pays for. Hindi is one of the most widely spoken languages in the world, so gaps in how AI models handle sensitive science in Hindi affect a very large audience.

What you will do, per the ad:

• Write expert-level prompts in Hindi on specialised scientific topics
• Evaluate and annotate model responses for scientific accuracy, helpfulness and appropriate handling of sensitive content
• Classify prompts and conversations against structured guidelines

The subject areas are chemical, biological, and radiological and nuclear science. You bring dual-use judgment: recognising legitimate research, teaching and safety questions versus requests that reach for dangerous capability, and checking how the model treats each in Hindi. The role assesses safeguards; it does not involve producing harmful content.

Expect to decide, often, how much English technical vocabulary is natural in a Hindi prompt. The ad does not say how Hindi-pure the writing should be, so ask during onboarding if unsure.

No AI experience is needed; Mercor trains you on the workflow.

Who qualifies

• A PhD in chemistry, biology or a closely related field, completed or in progress
• Enough depth to write across chemical, biological, or radiological and nuclear areas
• Native or near-native Hindi and business-level written English
• Deep familiarity with modern laboratory and computational techniques in your subfield
• Sound judgment on scientific safety and dual-use information

Nice to have: a clear specialism (organic or inorganic synthesis, molecular biology, microbiology, virology, genetics and similar), radiological and nuclear expertise from chemistry (radiochemistry, nuclear chemistry, energetic materials, radiation physics), work on chemical security, biosafety or hazardous-materials handling, and experience reviewing, grading or red-teaming technical content.

India or the wider South Asia region is preferred, not required.

What it pays

$23–27 per hour, Mercor's published figure. That is the lowest rate among the STEM versions in this series, just under Thai ($24–28), and well below European and East Asian ones ($48–81).

For an India-based PhD student or postdoc, the relevant comparison is a fellowship stipend, and flexible hourly work at this rate can add up to a meaningful supplement. Researchers abroad will see it very differently.

Payments are weekly via Stripe or Wise, based on services rendered.

Worth knowing

Good:

• One of the most active listings in the series: 12 hires this month when we checked
• PhD candidates qualify
• Fully remote on your own schedule, immediate start
• Uses real subject expertise

Less good:

• The lowest STEM rate in the series for the same PhD-level bar
• Hazardous-science topics are central to the work
• No stated weekly hours, project length or end client; projects can be extended, shortened or ended early
• Independent contractor, no benefits
• H-1B and STEM OPT candidates excluded
