About Prolific
Prolific is not just another player in the AI space – we are building the biggest pool of quality human data in the world.
Over 35,000 AI developers, researchers, and organizations use Prolific to gather data from paid study participants with a wide variety of experiences, knowledge, and skills.
The role
We’re looking for Materials Science Specialists to join our Expert Network to help train and evaluate cutting-edge AI models using real scientific expertise. If you have a background in materials research, engineering, or technical analysis, we’ll send you a quick 10- to 15-minute test to assess your skills and suitability for AI tasks. If successful, you’ll be invited to join Prolific as a participant, where you’ll get paid to train and evaluate powerful AI models.
Researchers looking for your skills tend to pay $40+/hr, depending on skills and experience level. You must be prepared to complete paid tasks that require one hour of uninterrupted work, though many are shorter.
What you’ll bring
- Educational Background: at minimum, a BSc (Bachelor of Science) in Materials Science, Metallurgy, Chemical Engineering, or a closely related STEM field.
- Technical Literacy: deep interest or experience in materials research, including the ability to interpret phase diagrams, crystalline structures, and property data.
- Analytical Rigor: strong attention to detail and the ability to concentrate on complex technical tasks for extended periods.
- Professional Verification: a valid LinkedIn profile or professional history to verify your credentials during the screening process.
- A PayPal account to receive payment from our clients
What you’ll be doing in the role
- AI Evaluation & Ranking: comparing multiple AI-generated technical explanations or research summaries and ranking them based on scientific accuracy and logic.
- Strategic Document Audit: reviewing Materials Science scientific papers alongside AI-generated graphical abstracts to identify inaccuracies or misrepresentations.
- Fact-Checking: verifying that the AI-generated data (formulas, material properties, and experimental results) faithfully represent the source scientific documentation.
- Model Alignment: providing high-level feedback to help AI models produce "enterprise-ready" corporate and scientific intelligence.
- Technical Verification: auditing the structural integrity of summaries involving complex chemical compositions and material behaviors.
Key Technologies
- Generative AI (LLMs): training and fine-tuning models specialized in STEM and corporate intelligence.
- Scientific Visualization: evaluating AI-generated graphical abstracts and data visualizations.
- Research Databases: navigating technical literature to provide "ground truth" data.
