Tips for Hiring Smart Contract developers

If you're interested in harnessing blockchain technology, consider hiring smart contract developers.

Smart contract developers can help you test, debug, and create smart contracts — blockchain algorithms that automatically execute, document, or control legally-relevant actions and events according to the terms of an agreement or contract. However, they can also help you develop blockchain projects, protect users from threat actors, and implement automatic transactions.

Read this guide to learn more about smart contract developers, what they do, and how much they make. We'll also cover how to hire a smart contract developer.

What is a Smart Contract Developer?

A smart contract developer is a programmer who writes, tests, and debugs smart contracts — blockchain network algorithms that run when certain conditions are met. Many companies hire them to create and implement blockchain platforms.

Smart contracts play a vital role in blockchain transactions. Every time someone performs an action on a blockchain, the blockchain automatically uses smart contracts to execute an agreement so that every participant immediately knows the outcome, without time loss and intermediary involvement.

Most smart contracts operate based "if/when... then..." statements. However, that doesn't necessarily mean they're simple. Depending on your needs, a smart contract can have as many stipulations as required.

What Can Smart Contracts Be Used For:

You can use smart contracts for many applications, including:

  • Personal investor accounts: Smart contract programmers can use smart contracts to create a front-end or user interface (UI) for personal investors' accounts. Users can then use the UI to interact with smart contracts or blockchains directly.
  • Fundraising: You can also use smart contracts for crowdfunding projects. Smart contract developers can do this by creating a smart contract and issuing tokens on the blockchain to attract the capital and interest of investors.
  • Decentralized applications (dApps): dApps, also stylized as dapps, operate on a blockchain. Like traditional apps, dApps can be created for various purposes, such as social media, finance, and gaming. Because they run on a blockchain, they are free from the interference and control of a single authority. Other benefits of dApps include lack of censorship, flexible development, and the safeguarding of user privacy.
  • Cryptoprocessing: Smart contracts can enable the acceptance of cryptocurrency for your personal account or project. Programmers can do this via crypto payment processing, internal billing, and token accrual.
  • Insurance apps: If you're running an insurance company, smart contract coders can use smart contracts to automate your services and policies, increase transparency, reduce claims processing and administrative costs, and prevent fraud. They can also use smart contracts to automate claims functions and payments.

How To Develop Smart Contracts

Blockchain participants and smart contract developers develop smart contracts by establishing the terms and stipulations of their smart contract. They accomplish this by:

  1. Determining how their data and transactions are represented on the blockchain
  2. Agreeing on the "if/when... then..." statements
  3. Pinpointing possible exceptions
  4. Creating a dispute resolution framework

Once the participants have agreed on the contract terms, the smart contract developers can start coding. Many smart contract programmers write their code from scratch, but organizations increasingly provide web interfaces, templates, and other tools to streamline and simplify smart contract creation.

Finally, the smart contract developers test and debug the smart contract to ensure it's working. The main way to debug smart contracts is caveman debugging, where developers print to check the contract flow and inspect variables' values.

What Does a Smart Contract Developer Do?

A smart contract programmer is primarily responsible for creating, testing, debugging, and deploying smart contracts. Additional responsibilities include:

  • Creating architecture for newly developed or existing software solutions using smart contracts and blockchain platforms
  • Creating nontemplate smart contracts
  • Integrating smart contracts into existing solutions
  • Establishing smart contract audits using manual and automated tools
  • Developing a comprehensive and effective economic model for your cryptocurrency project

What is a Smart Contract Developers Salary

Like other cryptocurrency professionals, smart contract developers typically earn high salaries.

The average smart contract salary depends on location. According to Web3, the average junior or entry-level smart contract developer in North America earns $140,000 to $200,000 annually. Here's the breakdown of smart contract developer salaries in other parts of the world:

  • Remote: $150,000 to $250,000 annually
  • South America: $112,000 to $150,000 annually
  • Europe: $80,000 to $135,000 annually
  • Oceania: $75,000 to $100,000 annually
  • Asia: $68,000 to $150,000 annually
  • Africa: $64,000 to $75,000 annually

The averages also differ significantly within continents due to seniority, with inexperienced coders making less than their experienced counterparts.

Entry-Level Salary for Smart Contract Developers

Junior or entry-level smart contract developers have under three years of working experience. As such, they tend to make less than their senior colleagues. A quick Google search reveals that most junior smart contract engineer salaries range from $80,000 to $120,000.

They are typically responsible for the following:

  • Writing smart contracts in one or more programming languages, typically Rust or Solidity
  • Testing and deploying applications across multiple blockchains
  • Applying computer science and mathematical concepts to design and implement dApps

Most companies expect junior and entry-level contract programmers to have the following skills:

  • Some knowledge of smart contract languages, such as Rust and Solidity
  • Strong communication and teamwork skills
  • The ability to work remotely
  • Some knowledge of cryptography — cryptography is the study and practice of techniques for secure communication in the face of adversarial behavior; it involves analyzing and constructing protocols to prevent the public or third parties from reading private messages
  • Some knowledge of security practices

Senior Smart Contract Developers Salary

Senior smart contract programmers have over five years of experience writing code in a major smart contract language and over three years of experience leading a software team.

Accordingly, they enjoy higher salaries than their junior colleagues. Job boards reveal that senior contract engineers typically range from $250,000 to $300,000.

Typical senior smart contract programmer duties include:

  • Writing, testing, and deploying smart contracts
  • Implementing smart contract designs with a focus on simplicity, security, gas efficiency, and ease of use
  • Creating smart contract systems for interacting with and managing smart contracts
  • Helping to build, scale, and manage a team of blockchain developers and engineers
  • Supporting the rollout, adoption, and scaling of smart contract platforms or apps
  • Mentoring and team members through mentoring, feedback, and career guidance
  • Actively participating in project report documentation and preparation
  • Researching and documenting engineering activities for both internal projects and consulting engagements

Senior smart contract programmers typically have the following skills:

  • Over three years of experience working in a smart contract development company
  • Experience with mission-critical software and distributed systems in one or more smart contract languages, including SmartPy, Solidity, Clarity, and Michelson
  • Excellent communication, teamwork, and leadership skills
  • The ability to work remotely
  • Familiarity and passion for the latest blockchain and security best practices
  • The ability to write secure code and prevent hostile takeovers of smart contracts
  • Experience using dApps like Aave, Uniswap, and Maker
  • Strong cryptography skills

How To Find and Hire Smart Contract Developers

Now that you know what a smart contract developer is and what they do, here's what you should do to find and hire smart contract programmers:

1. Find the Right Place to Source Smart Contract Developers

First, you need to find the right place for sourcing smart contract developers. Otherwise, you'll have difficulty attracting and retaining suitable talent. The top places for recruiting smart contract programmers are:

Job Sites

Job sites like LinkedIn, Monster, and Indeed can connect you with thousands of qualified smart contract developers. To get started, pick a site(s) and write a project or job description. Interested job seekers will then apply for your job through the site(s).

Job sites often provide many tools for locating suitable hires. Indeed, for instance, offers over 150 skills tests for evaluating potential candidates' knowledge, skills, and abilities. Similarly, LinkedIn offers multiple talent solutions, including:

  • Recruiter: An all-encompassing platform for hiring talent, Recruiter gives you up-to-date insights on over 740 million LinkedIn members, recommended matches to prioritize candidates and advanced search filters. You can also see your teammates' communication history with job seekers and track your messages' performance.
  • Jobs: LinkedIn Jobs empowers you to reach the right people at the right time. It targets your jobs to relevant members, even if they're not actively looking for jobs. It also lets you manage job posts based on how your hiring needs change throughout the year.
  • Talent Insights: A talent intelligence platform that empowers you to make smart hiring and workforce decisions, Talent Insights gives you talent pool data to refine and focus your search. It also gives you:
  • Real-time data, including company reports, talent supply and demand, and employer branding metrics
  • Over 12 billion data points on companies, skills, talent, jobs, and schools
  • On-demand talent intelligence tools with personalized recommendations, actionable insights, and learning resources
  • A 360-degree view of your competitors, organization, and the market

Freelance Platforms

If you don't have a steady stream of work and you want to save hiring costs, consider using freelance platforms to source freelance smart contract developers. Freelance workers provide many advantages, including:

  • Lower cost of hiring: Freelance programmers are typically less expensive to maintain than full-time employees. Unlike full-time workers, freelance coders charge per hour or project. As such, you only need to pay them when they're actually working. Meanwhile, you would have to pay full-time workers a monthly or yearly salary, even if you have no work for them. Plus, freelancers don't require benefits, while full-time employees do.
  • The ability to meet deadlines faster: Freelance employees can set their own schedules, which means they can work on holidays and weekends to meet deadlines faster. In contrast, employees don't work on holidays and weekends.
  • Lower overhead expenses: Hiring freelancers can also reduce overhead costs. That's because they can work from anywhere in the world. They also use their own equipment. Accordingly, you don't have to pay for overhead costs like office space, supplies, and equipment.

Examples of popular freelance platforms include Fiverr, Freelancer.com, and Upwork.

Tech Hubs

Another way to find fitting smart contract coders is via tech hubs — regions, suburbs, cities, and buildings that promote innovation for tech companies. To hire emerging and established smart contract programmers in tech hubs, you can:

  1. Fly to the tech hub: If you don't live or work in a tech hub, you can physically go to a tech hub to hire talent. Tech hubs are full of startup accelerators, co-working spaces, universities, and networking events for entrepreneurs, academics, and developers. Write compelling job ads and hand out flyers and other marketing materials to increase brand awareness.
  2. Hire remotely: If you don't have the money or time to go to the tech hub in person, you can hire remotely by creating an online job ad. You can then post your ad on job and freelance sites and target your ad to specific tech hubs.

Some of the best tech hubs in the world include:

Talent Marketplaces

Job sites, freelance sites, and tech hubs are great ways to hire smart contract coders. However, they all require you to create job ads and vet and interview candidates. This can be extremely time-consuming, especially if you have limited resources and staff.

Fortunately, talent marketplaces are here to help. Unlike traditional job sites and freelance sites, talent marketplaces provide access to thousands of pre-vetted tech talent. Just tell the hiring team about your business needs, and they will match you with suitable talent within a few days.

2. Write an Appealing Job Description

If you decide to hire smart contract coders through job sites, tech hubs, or freelance platforms, you must write an appealing job description to attract first-rate talent. However, you can skip steps two and three if you're hiring coders through talent marketplaces.

Here's what your smart contract developer job ad could look like:
