The work

You will create, solve, and explain advanced chemistry problems for large language model training. The work covers postgraduate-level concepts and combines written reasoning with chemical equations, diagrams, annotated structures, and other visual explanations.

You will also review model-generated chemistry content, add detailed annotations, and give constructive feedback. The role requires clear scientific communication and structured judgment when working through difficult problems independently.

  • Create and solve problems in organic, physical, and inorganic chemistry.
  • Work with stoichiometry, thermodynamics, electrochemistry, and chemical equilibrium.
  • Explain complex organic reaction mechanisms using clear reasoning and annotated chemical structures.
  • Develop reaction progress visuals, energy diagrams, equations, and other chemical representations.
  • Evaluate chemistry content and provide detailed annotations and useful feedback.
  • Communicate complex scientific ideas in simple, precise language.

What it pays and takes

This is a part-time, remote contractor assignment for an individual freelancer. The listing does not specify a pay rate. It is marked as entry level, but the work itself requires chemistry knowledge comparable to PhD-level study.

  • Time commitment: 20 or more hours per week.
  • Location: Remote and open worldwide.
  • Language: English.
  • Education and experience: A strong chemistry foundation comparable to PhD-level study is required.
  • Relevant background: PhD or postdoctoral study in chemistry, chemical engineering, biochemistry, or a related field.
  • Useful subject experience: Physical chemistry, organic chemistry, or inorganic chemistry.
  • Skills: Structured problem solving, research, analytical thinking, creative and lateral thinking, clear communication, detailed annotation, and constructive feedback.
  • Equipment: A reliable desktop or laptop and internet connection.
  • Work style: Self-motivated and able to work independently.
