Role details

We’re seeking chemists to join our AI training project. In this role, you will review AI-generated responses, evaluate the reasoning quality and step-by-step problem-solving, and provide expert feedback that helps models produce answers that are accurate, logical, and clearly explained. You will assess solutions for accuracy, clarity, and adherence to the prompt; identify errors in calculations, methodology, or conceptual understanding; fact-check chemical information across; write high-quality chemical explanations and model solutions that demonstrate correct methods; and rate and compare multiple AI responses based on chemical correctness and reasoning quality.

Your profile

  • You hold an MS or PhD in Chemistry or a related field in a high ranking university.
  • Confident in chemical reactions and stoichiometry, organic mechanisms, analytical methods, and physical/quantum chemistry.
  • Expert at fact-checking information using public sources across multiple domains. You communicate chemistry clearly and turn advanced theory into real-world solutions.
  • English proficiency C1 and above with excellent writing skills.
  • Background in research, analytical writing, debate, programming, or chemistry is preferred.
  • Bonus: Data labeling, RLHF, or AI model evaluation experience.
  • You enjoy applying chemical reasoning to evaluate and improve AI capabilities.
  • For PHD holders: you have developed or critically reviewed complex chemistry content (e.g., problem banks, proofs, textbook sections, research notes).

Key responsibilities

  • Develop AI Training Content: Create detailed prompts in various topics and responses to guide AI learning, ensuring the models reflect a comprehensive understanding of diverse subjects.
  • Optimize AI Performance: Evaluate and rank AI responses to enhance the model's accuracy, fluency, and contextual relevance.
  • Ensure Model Integrity: Test AI models for potential inaccuracies or biases, validating their reliability across use cases.
