Materials Science/Engineering Specialist - Freelance AI Trainer Project

Overview

Join to apply for the Materials Science/Engineering Specialist - AI Trainer role at Invisible Expert Marketplace. Are you a materials science expert eager to shape the future of AI? Large-scale language models are evolving from clever chatbots into powerful engines of scientific discovery. With high-quality training data, tomorrow's AI can democratize world-class education, keep pace with cutting-edge research, and streamline lab work for scientists everywhere. That training data begins with you—we need your expertise to help power the next generation of AI.

We’re looking for materials science and engineering specialists who live and breathe crystallography, thermomechanical processing, nanomaterials, polymer science, electronic materials, biomaterials, corrosion science, and composite development. You’ll challenge advanced language models on topics like phase transformations, microstructure-property relationships, materials characterization techniques (XRD, SEM, TEM), thermal analysis, additive manufacturing, materials failure analysis, and sustainability in materials engineering—documenting every failure mode so we can harden model reasoning.

Responsibilities

• Converse with the model on lab scenarios and theoretical materials science questions, verify factual accuracy and logical soundness, capture reproducible error traces, and suggest improvements to prompt engineering and evaluation metrics.


• Document failure modes to strengthen model reasoning and reliability.

Qualifications

• A PhD in materials science, materials engineering, or a closely related physical science field is ideal; peer-reviewed publications, lab-based testing, product design using advanced materials, or applied research signal fit.


• Clear, metacognitive communication - 'showing your work' - is essential.

Details

• Job title: Materials Science Specialist – AI Trainer


• Employment type: Contract


• Workplace type: Remote


• Seniority level: Mid-Senior Level


• Pay range: 8-65 per hour (final offer determined after evaluating experience, expertise, and geographic location)

Notes

As a contractor you’ll supply a secure computer and high-speed internet; company-sponsored benefits such as health insurance and PTO do not apply.
