Hire Blockchain Developers

Blockchain development is a niche area that has been steadily gaining momentum over time among major technology companies. This means that the demand for these experts is high, while the number of qualified developers is still relatively low.

Companies are, however, realizing the value and use cases for hiring a blockchain developer, although it is quite a challenge to find a good developer due to the current talent shortage. Dealing with high work rates, finding true experts (and eliminating those who pretend to be experts), and retaining them takes a lot out of a company.

That's why business owners and decision-makers must understand how to successfully find and hire blockchain development teams, including the skills and qualifications companies should look for, relevant interview questions, and the advantages of outsourcing this work.

What can a Blockchain developer do for a company?

A blockchain is a digital ledger or data record used to document valuable information. It is used, for example, to save financial transactions, payment histories and consumer identities, and is the technology behind Bitcoin and other cryptocurrencies.

This technology is also applicable in many other areas of business, from smart contracts to supply chains. It promises a renewed sense of security, transparency and accountability for the companies that use it.

A blockchain developer works within the engineering team to develop, launch, and maintain blockchain applications and systems. They are also responsible for the functionality and security of the relevant blockchain networks.

A good blockchain developer helps a company by creating tools that enable automatic execution, digital asset management, production classification, reliable business networks, and advanced security.

According to the US Bureau of Labor Statistics, there were 1,364,180 software developers in 2021 in the United States alone. Of these software developers, only 18,416 were active blockchain developers, according to the Electric Capital Developer Report . Only 1.3% of all software developers actively engage in blockchain development in the United States. This area is relatively new and requires a combination of many skills, which explains why it is sometimes quite difficult to find specialists whenever necessary.

Ethereum, Polkadot, and Cosmos are the three largest ecosystems for blockchain developers with 4,011, 1,400, and 950 monthly active developers respectively, as of 2021. These are some of the fastest-growing crypto ecosystems, with thousands of projects created every year.

Blockchain Developer Hiring Guide

There are few blockchain developers currently on the job market as this technology is relatively new. It also takes a lot to learn it properly, which makes it an even more valuable skill. That's why companies need to know where and what to look for when hiring a blockchain developer.

The choice between freelancers, in-house blockchain developers, or an outsourcing agency depends on the company's needs. Each type of candidate has its advantages and disadvantages.

Companies must know where to find these experts and how to create a compelling job description. Other developers may find the rates for this type of work attractive, but may not have the right skills to do it, so it's important for recruiters to ask the right questions during job interviews.

Job description

Companies looking to hire in-house blockchain developers need to create compelling and detailed job descriptions. However, the first step is to decide where they will look for talent.

Job boards like Indeed or Jooble are always good places to start. Although they are not specialized for blockchain developers, they still cover many different specialties and have good traffic. Using the right keywords is enough to get the job offer noticed. Smaller, specialized sites also search for job postings on these forums and repost them.

Companies that want to ensure their job posting only reaches true experts can try finding sites dedicated exclusively to hiring blockchain developers. Some of these specialized sites include:

• Crypto.jobs
• Cryptojobslist.com
• Blocktribe. with
• Beincrypto.com
• BitcoinJobs. with

The job description itself should be clear on all aspects of the available position. It should include the blockchain developer's main responsibilities, required skills and qualifications, benefits, and salary ranges.

Responsibilities of a Blockchain Developer

There are different types of blockchain positions available and each type serves a different role within a company. Blockchain developers can work as software UX designers, front-end developers, blockchain application developers, and smart contract engineers and developers.

Although these positions are slightly different from each other, the responsibilities of a blockchain developer remain similar. They must design, test and develop new blockchain applications that meet each client's requirements.

Specific responsibilities may include collaborating with management to review blockchain technology needs, staying up to date on the latest cryptology techniques, and maintaining and optimizing client-side and server-side applications, all while working with entire teams across the entire company.

Skills and qualifications

Blockchain development is a complex skill that requires a lot of knowledge. Ultimately, the skills and qualifications required depend on the company's needs. However, there are some basic skills that every blockchain developer must have.

Being fluent in different programming languages ​​is essential. At a minimum, blockchain developers must be comfortable with C++, Java, JavaScript, Node.js, Python, and Solidity (for Ethereum). It is also important that candidates have the ability to quickly write clean and simple code.

Experience with blockchain development platforms is also required. The right candidates should know how to work with Ethereum, Hyperledger and other similar platforms. Other relevant blockchain knowledge includes cryptocurrencies, smart contracts, and initial coin offerings (ICOs).

To narrow down your search for the perfect candidate, some extra skills and qualifications to look for are the following:

• Bachelor's degree in computer science, cybersecurity or similar
• Relevant previous experience
• Analytical, problem-solving and communication skills
• Attention to the details
• Data structure and database knowledge
• Ability to work in a team-based environment with a full development team

Interview Questions

Blockchain development is a complex field that requires a lot of knowledge. To hire the best of the best, recruiters must test their candidates. One of the best ways to understand candidates' core skills is to ask a few pertinent questions during the interview process.

Depending on the job requirements, some questions may work better than others. However, here are some basic questions that every blockchain developer should be able to answer:

What are the different types of blockchain networks? Explain.

There are three types of blockchain networks: public, private, and consortium or cooperative blockchains. Public blockchains like Bitcoin are open for everyone to join and participate. Private blockchain networks have a central point of control and function as peer-to-peer networks.

Consortium networks are accessible to many different companies. Each organization has access to data, transactions and assets through the same platform. This is useful for companies that want their partners to share responsibilities with them.

How does a blockchain recognize a block?

A hash identifies each block within a blockchain. Hashes function as a summary of the information or data within the block. They also include cross-border data, a timestamp, and a reference to the previous block, known as the parent block.

Is it possible to make changes to data after it has been written to a block?

Once you write data to a block, you cannot make changes to the data. There is no way to reverse this, and the only way to erase the data is to remove the blocks completely.

What are the most popular platforms for building blockchain applications?

Some of the most popular platforms for building blockchain applications include Ethereum, Hyperledger, Qtum, EOSIO, and IOTA. They allow software developers to create applications and other solutions using cryptocurrencies.

It is quite difficult to find a candidate with complete and perfect answers. However, any candidate who is comfortable enough with these concepts is certainly someone to consider when making the final decision.

When hiring a blockchain developer, testing their technical skills is just as important as knowing their general knowledge. Therefore, it is sometimes a good idea to provide candidates with some practice tests to assess their skills. Here are some sample tests that might be useful:

• Error Checking Tests – These tests have candidates compare at least two sets of data (such as two complete lines of code) to check for discrepancies. This is a measure of the candidate's attention to detail.
• Programming Language Tests – Blockchain developers must be comfortable with a wide variety of programming languages. Sometimes it is advisable to provide them with small tests in which they will have to use these languages, just to confirm that they have the necessary skills for the job.
• Logical Reasoning Tests – Logical reasoning tests attest to a blockchain developer’s problem-solving skills. This is an important skill considering that blockchain developers need to continue meeting new customer demands and developing new applications.

Depending on the complexity of the position offered by the company, recruiters may select more or different technical tests. The important thing is that they take the time to check the skills of potential candidates.

It may also be a necessary step to test candidates' interpersonal skills. Teamwork, adaptability, time management, communication and other interpersonal skills are extremely valuable in every blockchain developer.

How to Hire Blockchain Developers with Partners

Hiring blockchain developers with an outsourcing provider requires a lot of communication. The company needs to clearly express what its needs are and what it is looking for in the right candidate. This way, the supplier has a greater chance of connecting the company with the best talent. Here are some steps to follow when working with an outsourcing provider:

• Clearly Describe Requirements to the Outsourcing Agency It is important to define requirements and specifications as early as possible when hiring a blockchain developer through an outsourcing company. Companies must explain their projects so that candidates meet their expectations.
• Understand the type of blockchain developers the outsourcing agency offers As mentioned earlier, there are many different types of blockchain developers with different skills and responsibilities. It is important to know what type of developers are available and whether they meet the project requirements. Companies should ask outsourcing agencies how many blockchain developers they can provide and what kind of experience they have.
• Listen to Outsourcing Agency Suggestions Good outsourcing providers have a lot of experience matching companies with the right talent. It's possible that the agency has specific candidates in mind when meeting with different companies. Taking their suggestions seriously is usually a good idea, especially for companies that are new to this area and may not know exactly what to look for. Consider scheduling a virtual meeting or calling potential hires before making any decisions.

There are many advantages to outsourcing blockchain developers. These experts have a lot of experience in their field and their skills are sharp and specialized. Hiring and training a regular software engineer to fill the role of blockchain developer would be a huge investment that would also take a lot of time.

It is also much more cost-effective to hire a blockchain developer from a third-party company than to hire in-house. These developers often work remotely, so they already have access to all the technology they need. This way, the company does not need to invest any money in training or the necessary technology.

Start Building Your Blockchain Team

Leaders should hire blockchain developers through outsourcing agencies if they want to launch a startup and have a limited budget. It's also a good idea to turn to outsourcing providers whenever your company needs to move quickly on a project without having to spend a lot of time searching for the right developers.

As companies begin to recognize the importance of blockchain technology, the demand for qualified professionals increases. Blockchain developers are highly knowledgeable and can perform a wide variety of tasks within a company depending on their specific field. To ensure they get the best blockchain developers on the market, companies should make use of regular, dedicated job boards. Your job descriptions should be clear and attractive at the same time.

Potential candidates need to know exactly what kind of skills and qualifications the company is looking for and the responsibilities leaders expect them to take on. The selection process should include some type of test to help recruiters select only the most experienced candidates.

Taking advantage of interviews is a great opportunity. There, recruiters will ask candidates some questions to test them. Questions can be as basic or as difficult as the position requires.

Testing candidates on their technical and soft skills can also be an important step in the process. There are many software developers on the market, but only a small percentage of them actually have the skills required for blockchain development.

Companies can also consider hiring blockchain developers through outsourcing agencies. They can help them find the best candidates while saving time and money. Startups, companies with low funding or even those that don't have time for an exhaustive recruitment process would benefit from outsourcing.
