The work
You will create and assess difficult technical problems used to evaluate AI systems. The work turns real manufacturing and industrial engineering judgment into structured problems with realistic constraints, supporting data, correct analyses, and clear review standards.
- Design challenging problems in manufacturing process design, production systems, quality engineering, automation, supply chain, or operations modeling.
- Provide correct solutions and explain your reasoning clearly enough for another engineer to verify.
- Define objective criteria that help reviewers distinguish sound solutions from plausible but incorrect ones.
- Review problems created by other contributors for technical accuracy and sound methods.
- Identify problems that are ambiguous or cannot be graded reliably.
