Note: The job is a remote job and is open to candidates in USA. Weekday AI is seeking experienced CNC machining professionals to help develop a high-quality evaluation dataset for CNC manufacturing. The CNC Machining Expert will assess machining approaches, create objective evaluation criteria, identify safety and quality issues, and determine whether proposed solutions are suitable for real-world production environments.
Responsibilities
- 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
Skills
- • 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, workholding, 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
Benefits
- Fully Remote
- Flexible schedule
- Payments are made weekly based on services rendered through available payment platforms
- Independent Contractor engagement
