Overview

This part-time remote role uses your scientific knowledge to help make AI models safer when they respond in Croatian. You'll compose expert-level prompts across chemistry and biology, including radiological and nuclear topics, then judge the accuracy and safe handling of model-generated answers. Native or near-native Croatian and professional written English are must-haves; prior machine learning experience isn't. Your first day can be immediate, and the team trains you on the evaluation workflow.

What You'll Do4

  • 1Write expert-level Croatian prompts that probe scientific depth across chemistry, biology, and adjacent fields.
  • 2Review AI-generated answers for factual accuracy and appropriate treatment of dual-use or sensitive content.
  • 3Annotate model responses and conversations using the project's structured rubric.
  • 4Apply the provided classification guidelines consistently while evaluating prompt-response pairs.

Requirements6

  • 1PhD in chemistry, biology, or an adjacent science, either awarded or in progress.
  • 2Native or near-native Croatian plus solid written English for professional communication.
  • 3Up-to-date knowledge of lab and computational methods within your specialty, like organic synthesis or molecular biology.
  • 4Comfort applying safety principles when working with dual-use or hazardous scientific content.
  • 5Experience with radiochemistry, nuclear chemistry, or radiation physics is beneficial.
  • 6Prior coursework or research in biosecurity, biosafety, or chemical security helps you stand out.

Who Should Apply

You're a scientist with a PhD (or one well underway) who spends your day thinking about chemical synthesis, cellular mechanisms, or nuclear chemistry. This role asks you to translate that expertise into Croatian prompts that challenge how well AI models explain advanced topics. If you possess native-level Croatian, solid written English, and a preference for working in a narrow specialty rather than across many domains, you'll likely excel here. It's less suited to someone with only conversational Croatian or a generalist science background. Common reasons candidates miss the mark include a mismatch in scientific depth, such as a biochemistry degree without lab familiarity, or insufficient attention to dual-use safety concerns during the hiring process.

Salary Insight

The role pays between $48 and $52 per hour, with the higher rate typically going to candidates who bring rare technical expertise like radiochemistry or virology. For part-time remote PhD work, this is a solid rate and reflects the difficulty of finding bilingual scientists with safety-aware backgrounds.
