How Can You Hire A Good Blockchain Developer?

If you are looking for a blockchain developer, it is unlikely that you will find him/her on LinkedIn or some other employment-oriented sites. With experience, you’ll learn that real specialists do not advertise their skills too publicly. So, where can you find the real blockchain experts?

Blockchain developers are not the ordinary programmers. So, it would be logical to assume that, most likely, most professionals with really good experience in unrelated to blockchain software development won’t suit you. As a rule, most blockchain developers are the owners of cryptocurrency deposits, so you can start your search in the specific online communities (for example, Bitcointalk, Bitconnect, Reddit, etc).

As a result, because this type of job vacancy is rather new, most HR departments don’t even know what skills they should specify in the job post. Below we’ll give you some tips which will help you to hire a good blockchain developer.

6 skills of a competent blockchain programmer

Let’s start by reviewing the list of skills needed to be blockchain programmers.

Determine the scope of your employee’s authority. A simple statement: “I need a blockchain developer” does not carry any certainty. In order to understand who exactly you need, ask: “Do I need a developer who will build the blockchain architecture from scratch?” If your answer is ‘yes’, you should look for a full-stack dev. Then, you should decide which type of architecture you need (for example, public/private/consortium architectures are available for implementation).

Make sure they possess the great experience in software development. Your candidate should have a great experience in software development (frontend as well as backend). Also, he/she must have the knowledge of JS, Java, Python, C++ or other server languages. A good complement to these skills will also be experienced in developing FinTech software and in working with Big Data.

Ask the interviewee about his/her skills in working with cloud/edge computing. Cloud/edge computing help to build scalable software, so you should be sure that your future employer will be able to write code that could be upgraded easily and will cover a wider network infrastructure.

Find out to what extent your applicant is interested in the development of the cryptocurrency market. No matter how experienced and smart your candidate is, if he or she believes that the cryptocurrency is a “bubble that will soon burst,” you are unlikely to find a common language during your collaboration on the project.

Ask about the experience in writing smart contracts and digital tokens. Your interviewee must have experience working with cryptocurrency blockchains. So, it would be good if he/she has some skills in Clojure, Solidity and the other languages used in programming the smart contracts.

Learn whether the candidate is aware of the lawfulness of his/her activity. Some countries have rather strong limitations on cryptocurrency. Thus, if you plan to deploy ICO, your employee must clearly understand how his development activity is within the law.

To sum up, if you’re looking for a blockchain developer, you should throw aside your traditional approaches to finding a new contractor. As for the interview, you need to choose an extremely experienced full-stack developer who is interested in the latest IT trends. We hope that using our recommendations, you will be able to formulate requirements for your best candidate more accurately.
