Biologist, PhD

$90-120/hrRemoteFreelanceSTEM

About the Role

What if your years of rigorous scientific training could directly shape how AI understands and communicates biology to millions of people? We're looking for PhD-level Biologists to help evaluate and improve frontier AI systems — ensuring they reason accurately across molecular biology, genomics, physiology, systems biology, and beyond.

This is a fully remote, flexible contract role built for working scientists, researchers, and academics. Your deep domain expertise is the asset — no prior AI experience required.

  • Type: Hourly Contract
  • Location: Remote
  • Commitment: Flexible, minimum 15 hrs/week
  • Start Date: Rolling — staffed as projects launch

What You'll Do

  • Evaluate AI reasoning — critically analyze AI-generated answers to advanced biology questions, identify errors, and provide detailed, constructive feedback that directly improves model performance
  • Develop expert content — design and curate challenging biology questions and training datasets spanning a wide spectrum of subfields and complexity levels
  • Annotate domain knowledge — accurately label and categorize advanced biology concepts, scientific diagrams, experimental data, and specialized terminology
  • Map conceptual relationships — synthesize and connect complex biological principles, helping AI models grasp the depth and structure of the field across areas like genomics, cell biology, and systems biology
  • Review and refine — validate AI-generated solutions to research-level problems with the same rigor you'd apply to peer review

Who You Are

  • You hold a PhD in Biology or a closely related field with deep expertise in research, teaching, or advanced problem-solving
  • You have developed or critically reviewed complex scientific content — peer-reviewed publications, advanced curricula, laboratory research, or technical documentation
  • You can communicate challenging biological concepts with precision and clarity
  • You're detail-oriented, self-directed, and comfortable working asynchronously without hand-holding
  • You thrive on intellectually demanding work that rewards genuine expertise

Nice to Have

  • Specialization in molecular biology, genomics, systems biology, physiology, or a related subfield
  • Experience creating or evaluating advanced scientific assessments or educational content
  • Prior exposure to data labeling, RLHF, or AI model evaluation projects
  • Background in science communication or translating complex theory for broader audiences

Why Join Us

  • High impact — your expertise directly improves AI models used by leading research labs and global enterprises
  • Fully remote and flexible — work from anywhere, entirely on your own schedule
  • Genuine intellectual challenge — engage with research-level problems that actually require your PhD-level knowledge
  • Clear ownership — know exactly what success looks like with autonomy to deliver on your terms
  • Growth potential — consistent high performers take the lead on new programs and mentor incoming subject matter experts
  • Ongoing opportunities — strong contributors are first in line as new projects launch
