How to Hire a Database Developer

There are a number of important initial considerations when hiring a database 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: Are you hiring for a project or an ongoing need?
  • Urgency: How soon does the opening need to be filled? What happens while it remains open?
  • 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.

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.
  • You are hiring an employee as a direct placement but aren’t able to recruit effectively or efficiently with your internal staff. 
  • You aren’t familiar with current salary rates, market trends, and available skill sets

2. Hire an experienced freelancer

The freelance, or gig, economy continues to grow, with more talent available daily. Freelancers provide high-quality work without a long-term commitment. They can offer you a fresh perspective, more flexibility, and increase efficiency. While the freelance market isn’t ideal for every position, database developers are often a great fit. 

We recommend this option when:

  • Your need is project-based
  • The work can be performed remotely
  • You do not intend to direct the daily work activity
  • You are hiring for expertise your internal team does not possess
  • You do not require an employee to work onsite or follow a specific schedule

We recommend using either Toptal, Upwork, or both.


Toptal is an exclusive network of the top freelance software developers, designers, finance experts, product managers, and project managers in the world. Toptal vets its freelancers before making them accessible, ensuring their legitimacy. Top companies hire Toptal freelancers for their most important projects.

Upwork is a freelance talent network that helps individuals connect with experts in a variety of fields to accomplish project-based needs.

3. Post the 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

We recommend using CareerBuilder to find database developers:


CareerBuilder has been a trusted source for hiring since 1995. Reach 80+ million unique, diverse U.S. job seekers annually by posting your jobs through their talent acquisition channels.

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
