What Does A Solidity Engineer Do?


A Solidity developer is responsible for developing intelligent contracts in applications based on Ethereum using the Solidity programming language. They create smart contracts in decentralised applications and are in charge of creating high-security technologies. What does a Solidity engineer do?

What is a Solidity engineer?

With the increasing popularity of concepts like Web3 and decentralisation, the job market is going through a period of high demand for everything related to Blockchain. 

For professionals in the development field, this means new career possibilities in programming with languages ​​aimed at creating projects in this sector. 

One of these possibilities is Solidity engineering.

Role Overview - Solidity Engineer - responsibilities, skills, background and salary
Role Overview – Solidity Engineer

Combining elements of Python, C++ and JavaScript, Solidity was conceived in 2014 by a group of developers led by Christian Wrightwiener. It is an object-oriented programming language used by Solidity developers to program decentralised applications and smart contracts.

While it is compatible with many Blockchain platforms, Solidity is most often used on Ethereum. It is very similar to JavaScript and has support for inheritance, along with C3 linearization and multiple inheritance.

Is there a demand for Solidity developers? 

Because Solidity is a relatively new language, finding experienced programmers is becoming increasingly difficult and, according to Turing, this makes the demand for Solidity engineers extremely high at the moment.

What are Solidity engineers responsible for?

Now that you know a bit about Solidity, let’s take a look at what a Solidity developer does exactly. In general, this professional acts as a specialist in programming with the Solidity language. 

They are primarily responsible for developing smart contracts in decentralised applications based on Ethereum and other EVM (Ethereum Virtual Machine) Blockchains.

These developers are in charge of the network architecture and are responsible for developing its security standards

Solidity engineers also create reusable and efficient code and make sure that Blockchain technology is integrated seamlessly with existing applications.

Lastly, Solidity engineers work with product managers, designers, engineers, and other multidisciplinary teams to develop, plan, and collaborate on features and new ideas.

Responsibilities of a Solidity engineer:

  • Development and management of smart contracts and dApps
  • Network architecture and security standards development
  • Technical review assessment of existing Blockchain solutions
  • Create high-security technologies
  • Development of new features and improvements for existing Blockchain projects
  • Solidity code integration on different platforms
  • Integration of Blockchain technology with existing applications
  • Development of new ideas in collaboration with product managers and multidisciplinary teams

What are the skills of a Solidity engineer?

To start with, Solidity engineers must have extensive knowledge of Solidity as well as some basic knowledge of other programming languages such as C++, Python and JavaScript.

They should have a deep understanding of Blockchain technology and related concepts and ought to be familiar with the Ethereum Blockchain and its many functions and applications.

These developers must possess knowledge of ERC20, ERC721, and other protocols and should have a good understanding of fundamental encryption mechanisms.
