Blockchain software developers are key in front-end and back-end development, API development, and blockchain integrations. They are also involved in the client-side application development. While enterprises might divide their roles as blockchain developers, blockchain solutions architects, or blockchain project managers in smaller organizations or startups, the same person might have to fill multiple roles. 

3. Frontend Developers

Frontend developers are key in converting software design into computer languages like JavaScript, CSS code, C++, HTML, etc. It's the responsibility of the front-end developer to create a website visual that looks and works exactly as designed across various devices. A front-end developer should have strong knowledge of Node, Express, CSS, HTML, etc. 

4. Blockchain Application Developers

Blockchain application developers use various programming languages and codes to work at the backend of the application development. They use various languages like Java and C++ to create blockchain capabilities like distributed, decentralized, and public and private systems. 

5. Smart contract engineers

Apart from these position types mentioned above, you may also work with different blockchain developers who are experts in smart contract languages like Python, Solidity, Go, etc. The smart contract engineers focus on developing and editing smart contracts, end-to-end testing, smooth flow of the process, and security in smart contracts. 

Apart from these position types, you may also need to hire backend developers to provide technical support, design and develop APIs, conduct performance tests, and establish new technology requirements for better software design. 

Once you know the job responsibilities and company goals, narrow down your search based on the kind of blockchain technical knowledge you need your employee to have. Start looking for blockchain developers with the right skill set. Determine the proficiency level you need for the role — senior, junior, or intermediate positions. Noting down all these details can help you hire better.
