Bilingual Czech STEM Expert (PhD) — AI Safety | $53-$57/hr Remote

53–57/hr
Remote · Remote — Eastern Europe preferred
Posted September 4, 2026
part-time

Overview

This part-time remote role asks PhD-level scientists who are fully bilingual in English and Czech to help check and improve how advanced AI models reason about specialized technical topics in Czech. Your job involves writing deep, expert prompts on subjects like chemistry, biology, and radiological or nuclear physics, then judging whether the model's responses are accurate and safe. Previous machine learning experience is not required; the team provides the full evaluation framework and training. The position suits researchers who want their scientific judgment to directly shape smarter, safer AI behavior.

What You'll Do4

  • 1Compose detailed, expert-level prompts in Czech for scientific scenarios that test the model's reasoning on specialized topics.
  • 2Review AI-generated answers for factual correctness, usefulness, and appropriate handling of sensitive or dual-use content.
  • 3Annotate each response with structured notes about strengths and errors, following a defined rubric.
  • 4Sort prompts and conversation threads into categories using the provided safety and quality guidelines.

Requirements4

  • 1Hold a PhD in chemistry, biology, or a closely related field, whether completed or currently in progress.
  • 2Speak Czech at a native or near-native level and write English well enough for clear professional communication.
  • 3Demonstrate deep familiarity with modern laboratory and computational techniques used in your specific research area.
  • 4Show sound judgment about scientific safety and the ethical implications of working with dual-use knowledge.

Who Should Apply

The role is best suited for scientists who possess a PhD in chemistry, biology, or a closely allied discipline, and who can write about their niche with precision in Czech. It will frustrate someone who prefers broad research over focused, repetitive evaluation work. Interviewers often reject candidates who fail to show a clear subfield specialty or who cannot give concrete examples of handling sensitive or dual-use data. Additionally, if your Czech is only conversational, you will likely not meet the bar for native-level prompt writing.

Salary Insight

The pay for this part-time remote position is $53-$57 per hour. This rate sits above what most PhD-level research consultants earn for similar part-time work, reflecting the need for rare Czech-language science fluency and a high degree of responsibility.
