How To Hire The Best Solidity Developers - Essential Qualities To Look For

'Smart contracts bring the blockchain to life' Yes, you read that right. But who brings the smart contracts to life? That is none other than ‘Solidity Developers’.  They are the basement of every blockchain/crypto project, helping to turn the vision of Entrepreneurs into life. However, most of the blockchain startups are not getting the momentum they deserve due to the incapability of their developers.

That’s why hiring the best solidity developers in the industry is important for the success of the particular business. Are you building a DeFi app that'll change the world of finance or a play-to-earn game that'll revolutionize entertainment? This guide will equip you with the knowledge to hire the perfect solidity developers and assemble your dream team.

The Basic Qualities

This might seem obvious, but you'd be surprised. Make sure your recruits can code circles around a smart contract.

➤ Solidity Proficiency: They should be able to write clean, efficient, and secure Solidity code. Ask about their experience with different coding paradigms and best practices.
➤ Blockchain Knowledge: Solidity doesn't exist in a vacuum. They should understand blockchain fundamentals like decentralization, consensus mechanisms, and the Ethereum Virtual Machine (EVM).

Don't Get Hacked

Blockchain is all about trust, and that hinges on secure smart contracts. There are some technical ways to hire a dedicated solidity developer who can keep your project safe:

➤ Security Awareness: They should be paranoid about vulnerabilities. Look for experience with security audits and penetration testing. 
➤ Defensive Coding: They should be masters of writing code that's resistant to attacks like reentrancy and integer overflows.

Look for Well-Rounded Developers

Coding chops are important, but there's more to the story. Before hiring an offshore solidity developer some essential qualities might not be on a resume:

➤ Community Engagement: Do they participate in online forums and contribute to open-source projects? This shows passion for the space and a commitment to continuous learning.
➤ Problem-Solving Skills: Blockchain is a growing sector. They should be adaptable and able to think outside the box to solve unexpected challenges.
➤ Communication Skills: Technical skills are great, but can they explain complex concepts clearly and concisely? This is also important for smooth collaboration.
➤ Team Player Attitude: Building a successful project takes teamwork. Look for developers who can collaborate effectively and contribute to a positive team environment.

Where to Find Solidity Developers?

Now that you know what qualities to look for, the next step is finding potential candidates. Here are some places to start:

➤ Development Companies: There are various top-rated solidity development companies out there and have many solidity developers available for hire. You can review their profiles, read reviews from previous clients, and assess their portfolios.
➤ Blockchain Job Boards: Analyze famous websites like Crypto Jobs List, and Blocktribe in blockchain-related job postings. They attract candidates who are specifically interested in blockchain development.
➤ Professional Networks: Platforms like LinkedIn can be a great place to find and connect with experienced Solidity developers. Use LinkedIn’s advanced search features to find candidates with the skills and experience you need.
➤ Blockchain Communities: Engage with blockchain communities on platforms like GitHub, Reddit, and various blockchain forums. These communities are full of developers who are passionate about blockchain technology.
➤ Hackathons and Conferences: Attend blockchain hackathons and conferences to meet talented developers in person. These events are great opportunities to see developers in action and measure their skills and enthusiasm.

Interviewing Solidity Developers

Once you’ve found some promising candidates, the next step is the interview process that follows the traditional methods for a solidity development company. Firstly prepare a set of technical questions to assess their Solidity knowledge and problem-solving abilities. For example, you could ask them to explain how they would implement a specific smart contract feature or how they would handle a particular security concern.
 
If the candidate has a portfolio or GitHub repository, review their code before the interview. During the interview, discuss their coding style, design choices, and any challenges they faced. Consider giving candidates a practical test, such as a small coding assignment or a bug-fixing exercise. This will give you a hands-on assessment of their skills and how they approach problems.
 
Finally ask about their previous experiences, particularly focusing on projects similar to yours. How did they handle challenges? How do they stay updated with new developments in the blockchain space? These questions can give you insight into their work ethic and passion for blockchain technology.

Testing, Testing - One, Two, Three

Resumes and interviews are great, but the real test is their coding ability.  To evaluate a developer's skills use platforms like HackerRank to offer pre-built coding challenges.  Give them a small, well-defined coding challenge related to your project. This allows you to assess their problem-solving skills and code quality in a practical setting.

Making the Final Decision

Remember, hiring goes both ways. Consider all the factors we've discussed: technical skills, experience, problem-solving abilities, communication skills, passion, and cultural fit. It’s also a good idea to check references from previous employers or clients to get additional insights into their work ethic.

Final Words

A recent report by Zion Market Research predicts the smart contracts market will explode, reaching $9.85 billion by 2030 (it was only $1.75 billion in 2022). Making money out of this growing market may seem easy, but business owners should follow these steps before hiring an expert solidity developer to improve their projects.

Remember, as Vitalik Buterin, the co-founder of Ethereum, said, 'The blockchain isn't just a technical innovation, but also a social and economic one.' The most skilled Solidity developers are not just technically proficient but also have a keen understanding of how the blockchain industry is advancing.
