What you need to know before you hire a database administrator 

Keep these factors in mind before hiring a database administrator. 

Understand the role’s responsibilities

Before you recruit a database administrator, know what goes into the role. 

DBAs are more than just tech support for your databases – they’re the growth engineers for your data systems. They ensure databases can scale with your business, preparing for more traffic and maintaining speed as customer numbers increase. DBAs are also forward-thinking and fortify data against threats, crafting backups and recovery strategies for swift action during crises. 

Understanding the role’s responsibilities will help you make more informed hiring decisions. You’ll know which technical skills to look for and which personality traits make for adept DBAs.

Define the skill set

Clearly identify the technical and soft skills necessary for a DBA in your organization. For example, you might list in-depth knowledge of database replication, backup systems, and performance as non-negotiables. Or, prioritize soft skills like problem-solving and adaptability.

Defining these requirements will guide you toward a DBA who fits the technical bill and can also navigate the unique challenges your business may face. 

Know your database environment

Take stock of your current database environment and infrastructure. Does your company use cloud-based databases, on-premises servers, or a mix of the two? Knowing the environment and technologies used will help you find a professional with direct experience using your database architecture.

Consider your team dynamics 

Consider how a DBA will fit into your existing IT team and company culture. For example, will they need to work closely with software developers, system administrators, and data analysts? 

Having a clear picture of the collaborative and cross-functional nature of the role will help you identify a technically proficient DBA who’s also a good team player and communicator.

Determine your budget 

When budgeting for a database administrator, consider that the average base salary for the role in the US is between $87,000 and $128,000 per year – with variations depending on experience, education, industry, and location. 

Additionally, remember to include expenses like bonuses, commissions, health benefits, retirement contributions, and other incentives to attract top-notch talent.

Where to find skilled database administrators 

Many companies post job openings for database administrators on websites like LinkedIn and Indeed. These websites can bring in many applicants, but not all will be the best fit for your job. 

To find the right DBA, try some different, more creative methods.

3 creative ways to find database administrator candidates 

Consider these recruitment sources to find candidates with the right skills.

1. Online communities and forums

Engage with online communities and forums where database administrators frequently share their expertise. Platforms such as DBA Stack Exchange and Reddit's r/Database community are hubs for enthusiastic DBA professionals who actively discuss database management topics. 

These communities allow you to identify experts and establish direct connections with them.

2. Use specialized platforms 

Consider using specialized recruitment platforms, such as Otta and Dice, that focus on tech-savvy talent. You can access a pool of pre-screened candidates who likely have the precise data management, IT, and tech skills you're looking for.

3. University partnerships 

Partner with universities and colleges offering database-related programs. Collaborate on student projects, offer internships, or sponsor database-related competitions. This engagement not only helps you identify promising talent early but also allows you to shape and nurture future DBAs.

Common mistakes when hiring a database administrator 

Avoid these pitfalls when hiring a database administrator. 

1. Ignoring soft skills

While technical skills are essential, overlooking soft skills can cause issues. Database administrators don’t work in isolation – they must know how to collaborate with existing teams. They also need strong communication and problem-solving skills to keep everyone on the same page and resolve issues quickly.

For example, say a database administrator needs to help the marketing team understand how to use customer data. If the DBA can't explain this clearly, the marketing team might make mistakes in their campaigns. 

Focusing on both technical and interpersonal skills when searching for a DBA will help you find the best, most well-rounded candidate. 

2. Making a hasty hire

Rushing to hire a database administrator without proper evaluations can lead to costly mistakes. For instance, if you skip reference checks and later discover that the DBA has a history of not properly securing databases, your organization might face security breaches and data leaks. 

Taking the time to vet candidates carefully ensures the candidate you hire has a strong track record of security best practices, which is crucial for protecting your sensitive data and maintaining the integrity of your systems.

3. Overlooking documentation skills 

DBAs must document how they set up and manage databases. Otherwise, it can be difficult for others to understand how the databases are configured. This can cause delays when fixing problems or when a new DBA takes over the role.

So, don't underestimate a DBA's ability to document their work – it's like having a recipe that others can follow easily.
