**Workplace:** remote

**Department:** AI Training

## Description

**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

### What You'll Do

-   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.

### Minimum Qualifications

-   **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.

### Preferred Qualifications

-   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.

### Engagement Details

-   **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.

### Equal Employment Opportunity

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