The Work

You will evaluate AI-generated chemical engineering content and improve prompts, responses, explanations, and step-by-step solutions. Your reviews will focus on whether the work is accurate, complete, clear, logically sound, safe, and based on reasonable assumptions.

The role suits chemical engineers who can explain technical feedback in writing and judge whether AI handles real engineering constraints and process scenarios responsibly.

  • Evaluate AI responses on material and energy balances, thermodynamics, unit operations, separations, process control, scale-up, and plant troubleshooting.
  • Create realistic calculations, scenarios, and process-based reasoning tasks to test language models.
  • Find factual errors, flawed assumptions, missing constraints, unsafe recommendations, unit mistakes, consistency problems, and incomplete reasoning.
  • Review phase behavior, thermodynamic property use, separations logic, operability, process safety, scale-up, and plant troubleshooting scenarios.
  • Help AI explain assumptions, limitations, calculations, and professional engineering judgment clearly.
  • Support responsible technical communication, including when work should be escalated to a licensed engineer or site expert.
