How to Hire a CNC Machinist
There are a number of initial considerations when hiring a CNC machinist:
- Recruiting: Do you have the internal resources and tools to successfully source and recruit for this role?
- Complexity: Does your project require a senior professional, or is a mid- or junior-level inspector sufficient?
- Duration: Is this a one-time project or a permanent requirement?
- Management: Do you have the time and expertise to direct the work effort effectively?
- Urgency: How time-sensitive is this need? What happens if it remains unfilled?
- Headcount: Do you have room on your team for a new W2 employee, or should you consider alternate options?
Answering these questions will help determine the best course of action for your current hiring need. Fortunately, various great options exist for every scenario, no matter how unique. We recommend the following options when hiring a CNC machinist:
1. Use 4 Corner Resources (or another professional recruiting firm)

- You aren’t familiar with current salary rates, market trends, and available skill sets
2. Advertise your opening on a top job board
Your best option may be to advertise your opening on a proven job board. There are many widely used job sites out there that draw visits from qualified candidates.
