Chemistry AI Training Expert

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.
