CNC Machining Expert

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.

Responsibilities

• 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.

Requirements

• 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).

Skills

• Experience with hobbyist machines (Makera Carvera) and Haas machines (VF-2).
• Relevant skills in AI evaluation.
