How to Hire a Mechanical Engineer

There are a number of initial considerations when hiring a mechanical engineer:

  • 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 mechanical engineer:

1. Use 4 Corner Resources (or another professional recruiting firm)
