In short
micro1 is looking for experienced engineers, scientists, and university faculty to write technical problems that test how well AI systems handle real expert work. You do not need prior AI experience, because your knowledge of your field is what counts. This work may suit you if you work in aerospace, semiconductors, manufacturing, industrial engineering, or materials science and want flexible remote freelance work.
What you will do
- Design hard technical problems in your own field, with realistic limits and supporting data.
- Write the correct solution and explain, step by step, the reasoning that leads to it.
- Set clear rules for what counts as correct, so another expert reaches the same verdict.
- Review problems written by other contributors for technical accuracy and sound method.
- Flag unclear or impossible-to-grade problems instead of sending them in.
What you need to apply
- A Master's or PhD in engineering, physics, materials, or a closely related field.
- Principal, staff, or fellow-level experience at a major engineering organization or national lab, or a faculty post at a leading university.
- Deep expertise in at least one area, with hands-on ownership of your work.
- The ability to explain clearly why an answer is correct, so another expert can verify it.
Who can apply
The role is open to people worldwide, since no country restriction is stated. You need at least a Master's degree and can work on a freelance contract, with 5 openings available.
