Job description
Job Title: CNC Manufacturing Documentation Reviewer / CNC Job Pack Expert
About the Role
We are looking for experienced CNC manufacturing professionals to review real-world CNC job packs submitted by manufacturing companies, CNC shops, machinists, or production teams.
The role involves checking whether submitted CNC documentation is authentic, technically relevant, complete, and suitable for use in an AI evaluation / manufacturing workflow research project.
The submitted materials may include engineering drawings, CAD/CAM files, G-code, setup sheets, tooling lists, process plans, inspection reports, material certificates, control plans, job cards, and other manufacturing documentation.
This is a reviewer role, not a design or programming role. The main responsibility is to evaluate the quality and completeness of submitted CNC job packs.
Responsibilities
- Review submitted CNC job packs and confirm whether they appear to come from real CNC manufacturing work.
- Check that files are not publicly available, AI-generated, generic, or artificially created.
- Verify whether all files belong to the same part, job, drawing number, customer part number, or production workflow.
- Evaluate technical completeness of each job pack.
- Review engineering drawings, ballooned drawings, tolerances, material specifications, setup sheets, tool lists, process flow charts, control plans, and inspection documents.
- Check whether CNC production artifacts such as G-code, CAM output, toolpath documents, or setup instructions are meaningful and connected to the job.
- Identify missing or weak artifacts.
- Flag confidential, personal, customer, or company-sensitive information that should be redacted.
- Provide a short quality assessment and recommendation: accept, accept with minor issues, request more information, or reject.
Required Experience
Candidates should have practical experience with at least some of the following:
- CNC milling and/or CNC turning
- Reading engineering drawings and GD&T/tolerances
- CNC setup sheets and machining instructions
- CAD/CAM workflows
- G-code / NC files
- Tooling lists and cutting tools
- Process routing / job cards / travelers
- Inspection reports, QC checklists, CMM reports, or control plans
- Material certificates / mill test reports
- Real shop-floor manufacturing documentation
What You Will Review
A strong CNC job pack may include:
- Customer request, RFQ, PO, or internal work order
- Job card / route card / traveler
- Engineering drawing or ballooned drawing
- CAD files (STEP, IGES, DXF, DWG, or native CAD)
- CAM files, toolpath exports, operation sheets, or setup sheets
- G-code / NC files
- Tooling list
- CNC setup instructions
- Process flow chart or control plan
- Material specification or mill test certificate
- Raw material inspection report
- In-process inspection report
- Final inspection report / CMM report
- Photos of the part, setup, fixture, or machining process
Candidate Requirements
- Direct experience in CNC manufacturing, CNC programming, machining, or manufacturing quality control.
- Comfortable reviewing technical drawings and manufacturing documents.
- Understanding of what real CNC job documentation looks like.
- Ability to identify incomplete, fake, public, or low-value files.
- Detail-oriented with ability to provide clear written feedback in English.
- Available for part-time, project-based review work.
