About AI Training Work

AI training is the human side of building modern artificial intelligence. Specialists create examples, evaluate model outputs, and provide detailed feedback so language models can produce more accurate, useful, and well-reasoned responses.

• Turn expert knowledge into structured training content.
• Help improve how AI systems reason about technical subjects.
• Contribute to a fast-growing field with remote work opportunities.

The Role

OpenTrain is seeking a Chemistry AI Training Expert to create and solve advanced chemistry problems for language-model fine-tuning. You will convert postgraduate and engineering-level chemistry knowledge into accurate training questions, rigorous solutions, and clear explanations.

This is a fully remote, part-time contractor assignment requiring 20+ hours per week. The engagement may be extended based on performance and project needs. The opportunity is listed as entry level, while the work requires advanced chemistry expertise.

• Role: Chemistry AI Training Expert
• Subject area: Advanced chemistry problem solving
• Work arrangement: Fully remote contractor assignment
• Time commitment: 20+ hours per week
• Language: English
• Engagement: Part time, with possible extension

What You'll Do

You will develop technically accurate chemistry content and explain difficult concepts in a way that is rigorous, structured, and understandable. Your work may combine written reasoning with equations, annotated chemical structures, diagrams, visual representations, and simulations when useful.

• Create advanced chemistry questions and solve them with detailed reasoning.
• Analyze complex organic reaction mechanisms using text and annotated chemical structures.
• Solve chemical equilibrium problems with reaction-progress and energy diagrams.
• Address challenging problems in stoichiometry, thermodynamics, organic chemistry, and electrochemistry.
• Provide constructive feedback and detailed annotations for model-training content.
• Communicate scientific reasoning clearly using equations, diagrams, and simple language.

Requirements

You should have postgraduate-level knowledge across organic, physical, inorganic, and analytical chemistry, with analytical and research skills suited to complex problem solving. Knowledge comparable to postgraduate or PhD-level study is expected.

Strong written English is required. You must be able to explain advanced scientific ideas clearly, annotate content precisely, work independently, and collaborate remotely. A reliable desktop or laptop and a good internet connection are also required.

• Postgraduate-level chemistry knowledge.
• Ability to solve complex problems involving mechanisms, equilibrium, stoichiometry, thermodynamics, and electrochemistry.
• Ability to explain solutions with equations, diagrams, annotated structures, and accessible language.
• Strong analytical, research, feedback, and detailed annotation skills.
• Creative and lateral thinking for challenging chemistry problems.
• Self-directed remote work habits and effective collaboration.
• Reliable desktop or laptop and good internet connection.

Helpful Academic Background

Candidates pursuing a PhD or postdoctoral degree in Chemistry, Chemical Engineering, Biochemistry, or a related field are encouraged to apply. Relevant expertise may include physical chemistry, organic chemistry, inorganic chemistry, chemical equilibrium, stoichiometry, thermodynamics, and electrochemistry.

• PhD or postdoctoral study is encouraged.
• Relevant backgrounds include Chemistry, Chemical Engineering, Biochemistry, or a related field.
• Expertise across multiple chemistry disciplines is valuable.

Why This Work Matters

Every major AI system depends on people who prepare, review, and improve its training examples. In this role, your chemistry expertise will help shape how language models handle advanced scientific questions and communicate their reasoning.

• Apply real scientific expertise to emerging AI systems.
• Help make technical model responses more accurate and useful.
• Develop specialized experience in AI training and data annotation.
