About the role

Bring senior chemical expertise to AI evaluation projects focused on process balances, reaction systems, scale-up, and process safety. Review model responses and worked examples for incorrect calculations, missing physical constraints, and incomplete verification. Assess whether the reasoning meets professional standards for the stated task. Write reference answers and scoring criteria grounded in process balances, reaction systems, scale-up, and process safety. Explain consequential errors, evidence gaps, and the reasoning behind your corrections. This is remote, project-based contract work. Scope, hours, and assignments depend on project matching; the listed hourly range applies to matched work.

What we're looking for

  • 7+ years of substantive experience in chemical or process engineering.
  • Demonstrated senior-level judgment in process balances, reaction systems, scale-up, and process safety, with substantial responsibility for reviewing or delivering this work.
  • Ability to write precise reference answers, assess competing approaches, and justify corrections with traceable evidence.
