About the role
We're building a high-quality evaluation dataset for CNC manufacturing and are looking for experienced CNC machinists to help author and validate grading rubrics for CNC machining work. You'll bring real production-floor judgment to determine whether a machining approach would be approved or rejected for a production run, and clearly explain your reasoning.
- Contribute to text-only, objective, verifiable rubrics for grading CNC machining solutions across provided CAD models and machining context (stock, machine, tooling).
- Write clear verification rationale for each criterion.
- Review sample solutions and explain pass/fail outcomes.
- 5+ years of hands-on CNC machining experience.
- Strong production judgment - able to tell what would and wouldn't run safely on a real machine.
- Written English fluency (all deliverables are text-based).
- Experience with hobbyist machines (Makera Carvera) and Haas machines (VF-2).
