Five High In-Demand Technical Blockchain Roles

Named as the most in-demand hard skill of 2020 by LinkedIn, blockchain has been gaining momentum ever since it first appeared in the limelight as the underlying technology behind the world’s first and most famous cryptocurrency, Bitcoin. First proposed by Stuart Haber and W. Scott Stornetta in 1991 and then immortalized by Satoshi Nakamoto in 2009, this distributed ledger technology is now spreading its wings to all domains, from finance to governance and supply chain to healthcare. Naturally paving the way for the demand of highly skilled professionals who not only understand this phenomenon religiously but also those, who can employ the principles of this revolutionary technology to change the world for the better.

However, there exists a great disequilibrium between demand and supply of skilled blockchain professionals with the former outpacing the latter by miles. Consequently, this significant talent gap acts as an incentive for the professionals trying to set a foot into the blockchain market as the salary of the DLT professionals tends to be much higher than the contemporaries in all other industries. As per the State of Salaries Report published by the employment giant Hired, blockchain engineers and developers claim an average compensation in the range of USD 150,000 to USD 175,000 annually, which is significantly higher than the USD 135,000 average software engineer salary.

With the availability of a plethora of opportunities in a vast number of domains, supplemented by lucrative compensation options, blockchain is poised to shake up the IT recruiting market for years to come. So, if you are a professional fascinated by terms such as blockchain, distributed ledger, DeFi, Dapps, DEX, Cryptoeconomics and/or Smart Contracts but unable to figure out the career path that will lead you to this multi-billion industry, then drive straight into the five high in-demand blockchain/DLT roles and skillsets required to excel these roles, explained below.

Blockchain Core Developer

Popularly, any developer involved in the blockchain development process can be termed a blockchain developer. Technically, the blockchain developers or more prominently regarded as blockchain core developers, deal with the core of a blockchain platform and are primarily responsible for building the foundation of the proposed blockchain system. They are granted the authority and autonomy to undertake all the decisions concerning the network’s inner workings. Some of the main technical functions of core blockchain developers are:

  • Developing the architecture of the blockchain network
  • Designing the blockchain protocol
  • Deploying the consensus mechanism
  • Monitoring the security of the network and potentially dealing with the network’s cryptographical foundation


  • Programming languages: Blockchain in itself does not require mastery over some exclusive programming language. The majority of core blockchain developers are skilled in general-purpose coding languages such as Rust, Go, C++, Python, and Java
  • Extensive knowledge of various data structures such as Merkle trees, hash maps, graphs, and consensus algorithms 
  • A good understanding of peer-to-peer networking
  • Experience in backend/system development
  • Solid understanding of cryptography

Smart Contracts Developer or Dapp Developer

In layman terms, smart contracts are self-executing digital contracts (i.e. lines of code) that govern the functioning of decentralized applications (Dapps). A smart contract or Dapp developer utilizes the protocol built by the core developers to design and deploy Dapps on the application layer. Their whole profile revolves around the development, deployment, and supervision of these Dapps running on the blockchain network. The major functions to be undertaken by smart contract developers in the blockchain sector are:

  • Writing and implementing smart contracts
  • Developing the frontend and backend for Dapps
  • Developing platform integration APIs
  • Full-stack supervision


  • Programming languages: The holy grail of smart contract programming languages is Ethereum’s Solidity. Other than that, smart contract developers are usually strong in JavaScript and/or Node.js and/or TypeSrcipt, and have experience with React.
  • Full-stack (web) development experience
  • Knowledge of leading database technologies (MySQL, SQL, MongoDB, etc.)
  • Knowledge of different types of blockchains and ability to build network-specific Dapps
  • Good understanding of modern software development tools, testing frameworks, and CI/CD environments
  • Bonus: Understanding of the business logic behind DeFi, NFT’s and other blockchain use cases

Blockchain Quality Assurance Engineer

Quality assurance refers to the procedure of deploying relevant testing strategies to identify technical issues in a software/product in order to ensure strict quality delivery and to avoid any divergence from established quality control parameters. A blockchain assurance or testing automation engineer is responsible for maintaining quality in all areas of blockchain development. The QA engineer performs the following key duties:

  • Developing, writing, and executing manual and automated testing plans
  • Identifying and analyzing bugs and errors found during tests
  • Locating areas of improvement in products and suggesting up-gradation measures
  • Documenting and communicating the results to the software development team


  • Extensive experience in software development and testing
  • Experience in writing and executing automation test scripts 
  • Proficiency in the specific programming languages that are used at a certain company
  • Advanced understanding of CI/CD
  • Sound knowledge of DLT

Blockchain DevOps Engineer or BlockOps 

DevOps, as the name may suggest, acts as a bridge between the software development team and the software operations team to make the whole software development process more efficient and effective. It aims at eliminating the challenges posed by the “Wall of confusion” by streamlining the feedback-improvement loop with a focus on cross-functional automation and integration. The DevOps engineer or BlockOps play the following roles in an organization:

  • Accelerate overall software development lifecycles by undertaking best continuous integration and continuous delivery practices
  • Proactively monitor and maintain blockchain nodes
  • Develop secure and scalable blockchain infrastructure solutions
  • Monitor the deployment of services in a testing environment and analyze/resolve the issues for large-scale distributed systems
  • Implement ways to improve data reliability and quality
  • Work on automation and optimization of cloud-based infrastructure


  • Technical understanding of the general blockchain architecture and infrastructure
  • Strong working knowledge of continuous development tools like Jenkins, Gitlab, Spinnaker
  • Experience working with container ecosystems; particularly Kubernetes, Docker, and Ansible
  • Proficiency in operating monitoring systems (Nagios, Splunk, Prometheus)
  • Experience with cloud platform services (AWS, Azure, Google Cloud)
  • Knowledge of any modern coding language is a plus – and required for infrastructure engineers
  • Good people management skills
  • Bonus: Experience running blockchain full nodes

Blockchain Frontend developer

Frontend is that part of the website which is accessed and experienced by the end-users. Frontend development deals with making this user experience as smooth as possible, by visualizing the backend data and code into aesthetically pleasing and interactive graphical representations. For blockchain frontend developers, the task is particularly concerned with presenting tons of hashes into a readable and attractive format. Below are the set of chores that a blockchain frontend engineer may perform on a day-to-day basis: 

  • Write client-side code to create lightning-fast, user-friendly, and highly responsive web-based applications
  • Optimize web products for all devices (Desktop and Mobile) and operating systems (iOS and Android)
  • Build interactive and visually attractive user interfaces
  • Continuously test the end-product for bugs and performance issues
  • Collaborate with backend/QA developers and product team to improve existing features and integrate new functions


  • Mastery of client-side scripting languages (Javascript/Typescript, HTML & CSS)
  • Experience working with React React Native
  • Proficiency in developing UX/UI using tools such as Figma, Canvas, etc.
  • A good understanding of Angular and TensorFlow might also be expected
