Materials Scientist (AI Content Reviewer)

About the role

This is an hourly, remote contractor position where you will act as a Materials Science Subject Matter Expert. You will review AI‑generated materials science content, create high‑quality reference answers, and provide detailed feedback to improve the scientific accuracy of AI models.

Key responsibilities

• Develop AI training content by writing prompts and gold‑standard answers across topics such as metals, ceramics, polymers, composites, phase diagrams, heat treatment, mechanical testing, corrosion, nanomaterials and characterization.
• Evaluate and rank AI outputs, detecting hallucinated properties, incorrect processing recommendations, unsafe design assumptions, and misleading claims.
• Provide precise written feedback on scientific correctness, engineering logic, terminology, unit consistency, and microstructure‑property reasoning.

Required profile

• Bachelor’s degree or higher in Materials Science, Materials Engineering, Mechanical Engineering, Chemical Engineering, Metallurgy, Polymer Science, Nanotechnology, or a related field, or equivalent professional experience.
• Minimum C1 proficiency in English and at least 3 years of experience in materials science research, engineering, laboratory work, manufacturing, teaching, technical writing or academic review.
• Deep understanding of structure‑property relationships, crystal structures, phase diagrams, mechanical behavior, heat treatment, polymers, ceramics, metals, composites, corrosion and characterization techniques.
• Ability to identify hallucinated material properties, flawed microstructure reasoning, unsafe engineering suggestions and unsupported performance claims.

Required skills

• Materials science research
• Materials engineering
• Technical writing
• AI data training/annotation (preferred)
