Careers in Blockchain: Techies, Lawyers, Crime Hunters, and Beyond

2021-10-11 03:47:00

The complex and rapidly changing world of blockchain technology has opened up many new career opportunities. These include technical careers related to blockchain programming, quality testing, and system architecture, as well as business-side careers in areas such as product management, project management, and legal consulting.

Like any other industry, blockchain employs professionals across dozens, if not hundreds, of careers. This article will cover the most popular among them.


Popular Blockchain Careers

Blockchain Developer

Blockchain developers program blockchain platforms as well as the apps residing on these platforms. These developers fall into two main categories:

  • Blockchain core developers program the core of blockchain networks, such as Bitcoin (BTC), Ethereum (ETH), or Solana (SOL). Their role is to develop, maintain, and update the source code powering the blockchain’s functionality.
  • Blockchain app developers are involved mainly in programming the apps hosted on the blockchain networks.

Blockchain core developers use programming languages such as C++, Java, and Python. In addition to these languages, blockchain app developers may use blockchain-specific languages popular for smart contract development. The most common among these is Solidity, a de facto language of choice for smart contract development on Ethereum.

In addition to skills in a programming language used on blockchains, developers need to be familiar with the basics of cryptography and the architecture of decentralized ledger systems.

Blockchain Architect

Blockchain architects conceptualize and design the overall infrastructure of blockchain networks or apps. Due to blockchain’s decentralized nature, effective blockchain design is highly important. Therefore, blockchain architects should have a deep understanding of the overall blockchain technology, and how various parts of this technology interact.

While architects are not expected to be familiar with blockchain code, they need to thoroughly understand blockchain cryptography, transaction verification models, cross-chain interoperability, tokenization, and other key areas required for a functional blockchain network or app.

Blockchain Project Manager

Project managers steer and coordinate blockchain projects during the development stage. They are often the key link between the developer team and non-technical project stakeholders, such as product managers, UX designers, and business consultants.

Project management requires various skills, such as:

  • Coordinating work between different parts of the company.
  • Resolving issues between different stakeholders.
  • Effectively communicating the project’s progress to the management team and other parties.

On the technical side, this job requires proficiency in popular project management software. The market for project management software is extremely fragmented, and each project may prefer a specific tool, or let the project manager decide what’s best.

Currently, the largest providers of project management software are Slack, Atlassian, and Experience in using the project management tools from these vendors can help you get hired for a project management role.

Blockchain UX Designer

Most blockchain apps have a user interface to enable their functionality. UX designers are responsible for creating effective and easy-to-use user interfaces for these apps.

Typical skills required in this career include user research via feedback gathering, wireframing, and prototyping. The ability to communicate the finalized concepts to all stakeholders involved in the project is also important.  Additionally, UX designers are advised to have at least basic skills in HTML and CSS.

Blockchain Quality Engineer

A quality engineer’s job is to ensure that the entire blockchain platform and all its components are free from functional errors. Quality engineers extensively test the platform on the testnet, the trial environment where the project resides before being launched in the finalized version.

A key part of this job is to test the platform via use cases, test scenarios that mimic end-user activity to identify possible omissions in functionality.

Good engineers often have a mix of technical skills and deep business understanding. Technical skills help them identify functionality problems when reviewing the code, while good understanding of the project’s commercial goals help them spot errors in the platform’s business logic.

Blockchain Legal Adviser

Legal advisers advise key project stakeholders, such as founders, managers, and business advisers, to help keep the project on safe legal ground. This could involve issues of corporate structuring, initial coin offerings (ICOs), tokenomics, smart contracts, and more.

Legal advisers need thorough knowledge of the cryptocurrency regulations worldwide, and particularly in the project’s jurisdiction of incorporation. They also need to deeply understand the blockchain and cryptocurrency concepts, in addition to general legal areas, such as corporate structuring or taxation.

Blockchain Product Manager

Product managers are responsible for the overall success, development, and functioning of a specific blockchain product. The product could be an entire app, or a specific part of it. For example, many decentralized finance (DeFi) platforms offer a variety of products and services to their end users. The job of a product manager would be to lead a particular product stream, such as a lending function, on such a platform.

Similar to product managers in other industries, blockchain product managers are evaluated based on their product’s key performance indicators. These indicators may include metrics such as revenue, profit, TVL, and number of wallets signed up.

Blockchain Security Manager

Despite their strong security based on cryptography and trustless decentralized verification, blockchains are far from immune to hacker attacks.

Security managers are responsible for identifying security threats to blockchain platforms, and protecting the platform from these threats. Strong skills in cybersecurity are important in this career.

The biggest security threat for most blockchain projects is the theft of crypto assets from platform users’ wallets. In the year 2020 alone, blockchain cyber criminals stole $500 million. With losses of this kind, demand for blockchain security managers is only growing.

Key Industries for Blockchain Careers

Financial Services

A large part of the blockchain ecosystem is made of financial services apps, including both decentralized and centralized apps.

The apps offer a variety of financial services, of which the most popular are digital payments, lending and borrowing, crypto investment optimization, and crypto asset swaps. The growth of these apps fuels the demand for blockchain professionals on both the development and business sides.

Industrial Products and Manufacturing

Many manufacturing companies are using blockchain technology to optimize their supply chains. Device manufacturers are also using blockchain-based Internet of Things (IoT) solutions — an area that’s expected to grow further.
