CNC Machining Expert

Part-time position

Remote — Global

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.

What you'll do

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.

Minimum 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).

Preferred

Experience with hobbyist machines (Makera Carvera) and Haas machines (VF-2).

We consider all qualified applicants without regard to legally protected characteristics and provide reasonable accommodations upon request.

Contract and Payment Terms

You will be engaged as an independent contractor.
This is a fully remote role that can be completed on your own schedule.
Projects can be extended, shortened, or concluded early depending on needs and performance.
Your work at Mercor will not involve access to confidential or proprietary information from any employer, client, or institution.
Payments are weekly on Stripe or Wise based on services rendered.
Please note: We are unable to support H1-B or STEM OPT candidates at this time.
