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)

The heavy lifting is done for you when working with a top-tier staffing company like 4 Corner Resources. We source, screen, recruit, and deliver only the most qualified candidate(s), saving you significant time and effort throughout the hiring process while you remain focused on your core business. Understanding your needs and ensuring the right candidate for the position is the key to our success.

This is the best route to take when:

  • You need to fill the position quickly
  • You want access to a vast talent pool of high-quality, prescreened candidates
  • Your position is suited for temporary hiring services, contract staffing, or contract-to-hire recruiting, and you intend to direct the work activity.

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. If you have someone internally who can dedicate the time and energy to sort through applications and screen individuals effectively, this can be a great choice. 

We recommend using a job board when:

  • Your internal recruiting team has the knowledge and experience to assess candidate qualifications
  • You are hiring a direct employee and have time to manage the entire recruiting effort 
  • You have a process for receiving, screening, and tracking all resumes and applications
  • You are prepared to respond to all applicants

There are many career sites out there. Here are the two we recommend for a CNC machinist opening:

LinkedIn

LinkedIn is a social network for job seekers, professionals, and businesses. With this popular job site, you can enhance your brand and advertise your open position to a wide audience of motivated, qualified candidates. Job postings on LinkedIn are also extremely streamlined and user-friendly, making it even easier for candidates to apply. Additionally, applicants can use their LinkedIn profile instead of a resume to expedite the process.

3. Leverage your internal resources

You can utilize your own website, social media, and employees to assist in your search for top candidates. 

A company website posting should be the first step in notifying prospective candidates that you are hiring. Social media can also be a powerful tool for spreading the word about your new opening. As far as exposure is concerned, this option can be as good as some job boards when you have a large enough following across various platforms, like LinkedIn, Instagram, Facebook, TikTok, and Twitter.

Current employees are every organization’s greatest asset. Encourage your internal team to promote job openings to their network by offering cash and other incentives.

We recommend these options when:

  • Your brand has great name recognition
