Chemical Engineering Expert — Process AI Evaluation (Alpheva)
What the work involves
Alpheva is an expert network that pays credentialed professionals to train, evaluate and improve frontier AI models through project-based contract work. It is bringing on senior chemical engineers for AI evaluation projects focused on process balances, reaction systems, scale-up and process safety.
You'll review model responses and worked examples for incorrect calculations, missing physical constraints and incomplete verification, judge whether the reasoning meets professional standards for the stated task, and write reference answers and scoring criteria grounded in process balances, reaction systems, scale-up and process safety — explaining consequential errors, evidence gaps and the reasoning behind your corrections. Fully remote and asynchronous.
What you'll do
- Evaluate advanced domain tasks and AI-generated responses for factual accuracy and professional judgement
- 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
- Document errors, edge cases and the reasoning behind an ideal response
- Collaborate asynchronously with Alpheva's research and evaluation teams
Requirements & eligibility
- 7+ years of substantive experience in chemical or process engineering
- Demonstrated senior-level judgement 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
- Comfort applying current standards, methods and risk considerations from chemical engineering to AI evaluation
- Strong written English for documenting errors, edge cases and reasoning
- Able to work independently and asynchronously on project-based assignments
