Ways to hire Blockchain developers

If you are building a Blockchain development team from scratch, you may wonder how to do it properly. Below, we gathered several options that will help you access and hire Blockchain developers for your organization.

Freelance Blockchain developers

Freelance platforms such as Upwork and Fiverr are ripe with Blockchain developers for hire. However, looking for professionals through them can be akin to trying to find a needle in the haystack. In many cases, working with freelancers contradicts internal security policies. Moreover, managing freelancers can be challenging if you don't have enough resources for it. Thus, it only makes sense to cooperate with freelance Blockchain developers if your project is short-term.

In-house Blockchain development teams

On the other hand, if you deal with a long-term project, it can be reasonable to build a local Blockchain development team. By hiring developers in-house, your business gains more control over the development process, however, it requires significant investments.

If the cost of hiring locally doesn’t pose a problem for you, you can post a vacancy on one of the platforms for employers, for example, Indeed, Jooble, LinkedIn, etc. Though they may not be tailored to Blockchain development, they are popular among job seekers. To make sure relevant candidates find you, optimize the job posting with specific keywords, for example, "Blockchain programmer" or "Blockchain dev." A well-written job posting will help you find and hire Blockchain developers faster. When creating the job post, you may want to include the following:

  • Describe your company, project, and your goals;
  • Outline the tasks your Blockchain developer should solve;
  • List skills you need your applicants to possess;
  • State must-have years of experience;
  • Describe the main responsibilities of your Blockchain developer.

When you have a pool of candidates, prepare to interview them. The interview questions should cover the Blockchain developers' skills as well as their cultural fit. Some examples of questions may include the following:

  • How many years of commercial experience do you have with Blockchain?
  • What are the main challenges of Blockchain development?
  • Do you have experience in Blockchain app development?
  • Are you familiar with cryptography in Blockchain?
  • What programming languages for Blockchain do you work with?
  • What project management tools do you use in your work?
