When Should I Hire a Dedicated Smart Contract Developer?

You may wonder: What does a smart contract developer do? Smart contracts are programs stored on a blockchain. These programs automate an agreements' execution and run once predefined conditions are met. Everyone participating becomes immediately aware of the outcome, reducing wait times. Smart contracts also automate workflows by triggering actions automatically in response to certain circumstances.

“Smart contracts based on blockchain technology are one of the most significant interventions in the field of technology.”, Georgia Weston, blockchain specialist with 101 Blockchains

Smart contract applications include reducing friction in international trade and increasing visibility between suppliers and retailers. These contracts function without a middle party and increase cost-effectiveness — no agent, lawyer or broker is needed. Neither company has to hire or place trust in a third party. 

What are Smart Contract used for?Smart contracts are used in businesses for various purposes within blockchain and decentralized applications (DApps). They automate, verify, and enforce the terms of agreements and transactions, reducing the need for intermediaries. Common applications include supply chain management, financial services, and tokenization of assets.
Advantages:1. Trust and Transparency: Smart contracts provide trust and transparency as code execution is visible on the blockchain.
2. Automation: They automate processes, reducing the need for intermediaries and streamlining workflows.
3. Security: Smart contracts, when properly written, are highly secure, and their tamper-proof nature reduces fraud risks.
Disadvantages:1. Immutability: Once deployed, smart contracts are immutable, and errors or vulnerabilities are challenging to rectify without significant disruption.
2. Complexity: Writing secure and efficient smart contracts can be complex, and the lack of centralized authority for dispute resolution can be challenging.
3. Cost and Resource Intensity: Developing and deploying smart contracts can be costly, and it often requires knowledge of blockchain technology.

What Skills To Look For When Hiring a Smart Contract Developer

Technical skills are a significant part of the portfolio for a smart contract developer. Without them, the job cannot be done. They include:

  • Data structure
  • Cloud computing
  • DevOps tools such as Kubernetes and Docker
  • Interoperability skills
  • Cryptography
  • Coding languages, including Python, HTML, CSS and JavaScript

Essential soft skills of a successful smart contract developer include:

  • Attention to detail
  • Relationship building
  • Effective communication
  • Organization
  • Creativity

Soft skills are vital for long-term success in the tech industry. Codes and programming languages evolve and eventually become extinct, rendering that knowledge archaic. However, a successful freelancer smart contract developer is creative and organized enough to keep learning. People skills can help a developer have a quite successful career.

How To Hire Smart Contract Developers

The need for qualified smart contract developers continues to grow as the world finds new ways to utilize blockchain platforms. Various industries already use smart contracts, including:

  • Banking and FinTech
  • Digital identity and IP protection
  • eCommerce and retail
  • Gaming
  • Insurance and legal contracts

Although smart contract platform basics remain the same, you may choose to look for developers who have experience in your industry to best meet your business goals.

Before you can build your team of developers, you must first define your project. Outline details such as:

  • Goals, nature, and scope
  • Timeframes and duration
  • Number of developers you need
  • Budget
  • Role description, desired and required qualifications

You must also decide whether to hire employees or freelancers. Each structure has pros and cons, but utilizing freelancers has many benefits.

The base rate you pay freelancers is often less than employees, but you get the same quality of work. Hiring employees means additional payroll tax, overhead, and benefits costs; you won’t have these expenses with freelancers.

It is often challenging to source developers with rare or niche skill sets in local talent pools; you can take advantage of global freelance talent networks like Toptal to find these developers. With video conferencing capabilities, your team can collaborate from wherever they are.

You will need to decide if you’ll hire entry-level, mid-, junior-, or senior-level developers. For an extensive smart contract design project, you may need a combination of skill levels and a smart contract engineer for advanced needs. Smaller tasks requiring only a few developers may indicate a specific skill level, but how do you know?

Skill levels basically reflect the amount of experience developers have using a particular skill. Senior developers may or may not possess complex skills, but they likely have project management experience. Engineers typically have more qualifications than even senior developers.

One skill level isn’t necessarily better than another for some smart contract creation needs. Your budget may be a determining factor because developers with more experience typically charge more.

Tips For Writing a Smart Contract Developer Job Description

With the high demand for smart contract programmers, they can be picky about the positions they accept. You need to craft an appealing job description that convinces these developers that they should choose your company over others.

Paint your company positively, describing its culture, brand, goals, achievements, and projects. Explain the project you’re about to launch and the specifics of open positions. Include relevant details, such as:

  • Responsibilities
  • Project type, goals, and projected duration
  • Hiring method (part- or full-time, remote, or freelance)
  • Desirable and required qualifications

Use the top sites in our list to source and identify the best candidates for your team. If you’re uncomfortable performing technical interviews, choose sites like Toptal that pre-vet every developer.

Business owners should create questions and a scoring model for all potential candidates to align with fair and unbiased hiring practices when preparing for interviews.

Common Interview Questions To Ask When You Are Looking To Hire a Smart Contract Developer

Even if you choose pre-vetted candidates, you should still ask a few technical questions during interviews. The questions and answers themselves aren’t necessarily as important as how developers respond. Do they have to think carefully before replying, or does the information come easily?

Ask questions such as:

  • Do smart contracts have legal standards?
  • Would you use dApps for my project?
  • Do you prefer Vyper or Solidity, and why?

You can gauge how solid each answer is, along with the applicant’s comfort level, confidence, and communication skills.

You probably won’t interview candidates without the right technical skills. These conversations allow you to assess crucial soft skills and determine how well a candidate will integrate into your team. Desirable soft skills include:

  • Active listening, verbal, and written communication skills
  • Ability to work well under pressure
  • Collaboration and leadership skills
  • Confidence and self-worth (without arrogance)
  • Creativity, innovation, attention to detail, and critical problem-solving skills

Design a purposefully vague situational question. Your goal is to make candidates ask for the details you omit before they provide answers. This technique offers invaluable insights into multiple soft skills.
