How to Hire a C++ Developer

Consider the following when hiring a C++ developer:

  • Recruiting: Do you have the knowledge, tools, and resources to attract and screen candidates?
  • Complexity: Do you need a senior professional, or will mid or junior-level skills and experience suffice?
  • Duration: Is this a one-time project or an ongoing need?
  • Management: Do you have the time and expertise to direct the work effectively?
  • Urgency: How soon does the work need to be completed?
  • Headcount: Do you have the budget and approval for an internal employee, or should you consider alternate options?

Answering these questions will help determine the best course of action for your current hiring need. Fortunately, great options exist for every scenario. These are our recommendations:

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.

  • 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

3. Hire an experienced freelancer

Connect with seasoned professionals on UpworkToptal, or Fiverr. The freelance, or gig, economy continues to grow, with more talent available every day. Not every position is ideal for the freelance marketplace, but a C++ developer is often a great fit. We recommend this option when:

4. 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
  • You can consistently monitor and respond to candidate activity through your website and social media accounts
  • You have a process in place to quickly and broadly communicate job openings and requirements
  • You have an effective employee referral program in place
