Beyond Bitcoin: The Multi-Faceted Role of a Blockchain Engineer

Beyond Bitcoin: The Multi-Faceted Role of a Blockchain Engineer

As companies across various industries explore the potential of blockchain to improve efficiency, security, and transparency in their operations, the demand for skilled blockchain engineers continues to increase.

In this article, we will once again explore what a blockchain engineer’s jobs entail (skills and qualifications) but will focus on a particular industry or sector, and explore what’s required to become successful.

This stems from working in this industry and noticing that the job title “Blockchain Engineer” means different things to clients, and mainly depends on the industry and/or their business needs.

Blockchain Engineer in a Centralised Exchange

As a software engineer working in a CEX, you are responsible for listing new tokens on exchanges by leveraging full-stack technology, such as TypeScript, JavaScript, and Node.js. Your responsibilities would include developing and maintaining the backend and frontend components of this exchange, ensuring that they function smoothly and efficiently.

You would need to work closely with other engineers to integrate various blockchain protocols and smart contracts into the exchange’s platform, as well as collaborate with the exchange’s business development team to identify new tokens to list. Additionally, you would be responsible for ensuring the security and scalability of the exchange’s infrastructure, as well as identifying and resolving any technical issues that may arise.

Overall, this role requires a strong understanding of blockchain technology and its associated programming languages, full-stack development experience would be ideal in these situations, and of course, the ability to work collaboratively with other team members.

Blockchain Engineer in an Algo Trading Company

Blockchain technology has revolutionised the world of finance by offering a new way to securely and transparently record and transfer value. As decentralised finance (DeFi) has gained traction in recent years, there has been a growing need to connect DeFi platforms with traditional centralised finance platforms to enable the seamless exchange of assets and data.

To meet this need, blockchain engineers have taken on the responsibility of developing and maintaining the technical infrastructure required to connect these different financial systems. This work involves designing and implementing APIs and protocols that enable the exchange of data and transactions between DeFi and CeFi platforms. Additionally, blockchain engineers may develop smart contracts and other blockchain-based solutions that enable interoperability between different systems.

Blockchain Engineer in a High-Frequency Trading Company

In a high-frequency trading (HFT) company, a blockchain engineer would be responsible for designing, implementing, and maintaining the technical infrastructure that enables the efficient and secure execution of high-volume trading strategies. This would involve developing and maintaining the backend and frontend components of the trading platform, including order management systems and execution algorithms.

To increase the efficiency and security of transactions, the blockchain engineer would also integrate blockchain technology into the trading platform. They may also design and implement smart contracts and other blockchain-based solutions to enable secure and transparent settlement of trades.

Blockchain Engineer working on a Layer 1 Blockchain

In a layer 1 protocol firm, a blockchain engineer would be responsible for designing, developing, and maintaining the technical infrastructure of the underlying blockchain network. Layer 1 protocols are the foundational layer of the blockchain network and are responsible for establishing the rules and consensus mechanisms for how the network operates.

Specifically, a blockchain engineer in a layer 1 protocol firm may be responsible for:

  • Developing and maintaining the blockchain’s core consensus mechanism, which determines how transactions are validated and added to the blockchain.
  • Designing and implementing smart contract functionality, which enables the creation and execution of decentralised applications (dApps) on the blockchain.
  • Collaborating with other engineers and stakeholders to identify and address technical challenges related to the scalability, security, and performance of the blockchain network.
  • Ensuring the integrity and stability of the blockchain network, including monitoring and responding to potential security threats or other issues.
  • Staying up to date with the latest developments in blockchain technology, including new consensus mechanisms, programming languages, and other tools and frameworks.

Overall, a blockchain engineer in a layer 1 protocol firm must have a deep understanding of blockchain technology and be capable of developing complex solutions that address the unique technical challenges of the underlying blockchain network.

Blockchain Engineer working in a Metaverse firm

A blockchain engineer working on tokenising real-world assets for a metaverse project would be responsible for a range of tasks; This would include designing and implementing smart contracts that allow for the creation of digital tokens that represent real-world assets, such as real estate, artwork, or commodities. They would also be tasked with developing and integrating tools and frameworks that enable the seamless exchange and trading of these digital tokens within the metaverse project.

Ensuring the security and transparency of the asset tokenisation process would also be a key responsibility of the blockchain engineer, which would include implementing robust identity verification and Know Your Customer (KYC) procedures.


Despite the varying responsibilities and areas of focus, all blockchain engineer roles share a common thread: a deep understanding of blockchain technology and its applications. This includes knowledge of distributed ledger systems, cryptography, consensus algorithms, smart contracts, and decentralised applications (dApps).

In addition to technical expertise, blockchain engineers must also understand the industry and ecosystem in which they work. They must stay up to date with the latest developments and trends in the blockchain space and be able to identify opportunities for innovation and improvement.

📅 This Week in Crypto 📅

Blockchain technology can help solve current issues with settlements, according to the deputy chief executive of Sberbank. Russia’s largest bank is working with other financial institutions to develop blockchain-based payment applications, the banker revealed.

After an implosion of prominent crypto firms in 2022, top executives at surviving firms are looking for new ways to market products that many consumers now distrust — and to distance themselves from former colleagues and mentors who could face years in prison. Some companies are trying to capitalise on the growing interest in artificial intelligence, with crypto schemes that feature convoluted A.I. tie-ins. Others are looking to replace the word “crypto,” arguing that the industry’s original nomenclature has become irredeemably tainted.

Hong Kong is accelerating toward its goal of becoming a global crypto hub, according to the region’s Secretary for Financial Services and the Treasury. In a Monday speech at the Aspen Digital Web3 Investment Summit in the east Asian business hub, Christopher Hui said that the city had received interest from over 80 companies wanting to set up shop in Hong Kong.
