CNC Machining Expert

This role is for one of our clients

Compensation: $120-$175 per hour

We are seeking experienced CNC machining professionals to contribute to the development of a high-quality evaluation dataset for CNC manufacturing. In this role, you will apply your real-world production experience to assess machining approaches, develop objective evaluation criteria, and determine whether a proposed solution would be suitable for an actual production environment.

You will bring practical shop-floor judgment to evaluating machining strategies, identifying potential safety or quality issues, and explaining why a solution should be approved or rejected.

Requirements

• Contribute to the development of text-based, objective, and verifiable grading rubrics for CNC machining solutions.
• Evaluate machining approaches across provided CAD models and relevant manufacturing context, including:
• Stock material
• Machine capabilities
• Tooling
• Toolpaths
• Machining strategy
• Define clear criteria for determining whether a machining solution is production-ready.
• Provide concise verification rationale explaining the reasoning behind each evaluation criterion.
• Review sample CNC machining solutions and determine whether they should pass or fail.
• Identify unsafe, impractical, inefficient, or technically incorrect machining approaches.
• Apply real-world production knowledge to ensure evaluation standards reflect actual CNC manufacturing practices.

• 5+ years of hands-on professional CNC machining experience.
• Strong understanding of CNC machining processes and production workflows.
• Demonstrated production-floor judgment and the ability to determine whether a machining approach can be executed safely and reliably on a real machine.
• Ability to identify potential issues involving tooling, machine constraints, work holding, toolpaths, feeds and speeds, or machining strategy.
• Strong attention to detail and analytical reasoning.
• Excellent written English communication skills, as all deliverables will be text-based.
• Ability to clearly explain technical decisions and pass/fail judgments.

• Experience working with Haas CNC machines
  , particularly the Haas VF-2.
• Experience with hobbyist or desktop CNC machines, including the Makera Carvera
  .
• Familiarity with CAD/CAM workflows and interpreting machining plans or CNC programs.
• Experience training, mentoring, or supervising CNC machinists.
• Previous experience reviewing machining processes for production readiness, quality, or safety.

• Role: CNC Machining Expert
• Work Arrangement: Fully Remote
• Engagement Type: Independent Contractor
• Schedule: Flexible
• Projects may be extended, shortened, or concluded early depending on project requirements and performance.
• Payments are made weekly based on services rendered through available payment platforms.
• The engagement will not require access to confidential or proprietary information belonging to any employer, client, or institution.
• H-1B and STEM OPT candidates are not currently supported.

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