The work

You will help improve AI systems that answer materials science questions. The work combines technical writing, model evaluation, fact-checking, and detailed feedback.

  • Write prompts and accurate reference answers for materials science topics.
  • Review, rank, and explain the quality of AI-generated answers.
  • Check scientific accuracy, engineering reasoning, terminology, clarity, units, physical plausibility, and relevance.
  • Assess microstructure and property relationships, experimental interpretations, and technical recommendations.
  • Identify incorrect material properties, flawed processing advice, incorrect diagrams, unsafe design assumptions, unsupported performance claims, and overconfident conclusions.
  • Write technically accurate rewrites and model answers while applying review guidelines consistently.

Requirements

  • Time: 20 or more hours per week.
  • Work setup: Remote, with reliable and self-directed collaboration across time zones.
  • Language: Professional fluency in English.
  • Education: A 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.
  • Experience: At least three years in research, engineering, laboratory work, manufacturing, teaching, technical writing, academic review, or related scientific or engineering work.
  • Knowledge: Structure-property relationships, crystal structures, phase diagrams, mechanical behavior, heat treatment, polymers, ceramics, metals, composites, corrosion, and characterization techniques.
  • Skills: Strong technical judgment, careful attention to detail, and the ability to follow detailed guidelines consistently.
  • Skills: AI training, Ceramics, Composites, English, Materials engineering, Materials science, Metallurgy, Phase diagrams, Polymers, Scientific review
