Manchester, United Kingdom Unreal Gigs Full time

Are you passionate about ensuring the security, performance, and reliability of blockchain systems? Do you thrive on identifying vulnerabilities and optimizing decentralized applications to meet the highest standards? If you’re excited about testing and validating blockchain networks, smart contracts, and decentralized applications (dApps), then our client has the perfect role for you. We’re looking for a Blockchain Quality Engineer (aka The Decentralized Assurance Expert) to lead the testing and quality assurance of blockchain systems, ensuring they are secure, scalable, and ready for real-world applications.

As a Blockchain Quality Engineer at our client, you will collaborate with blockchain developers, smart contract engineers, and project managers to build comprehensive test plans and ensure the highest level of quality across blockchain ecosystems. You’ll focus on identifying vulnerabilities, optimizing performance, and making sure that all decentralized systems run smoothly, securely, and efficiently.

Key Responsibilities:

  1. Test Blockchain Systems and dApps:
  • Develop and execute comprehensive test plans for blockchain networks, smart contracts, and decentralized applications (dApps). You’ll test for functionality, performance, security, and scalability across different blockchain platforms like Ethereum, Solana, or Hyperledger.
Smart Contract Auditing and Testing:
  • Conduct in-depth audits and testing of smart contracts to ensure security and reliability. You’ll look for vulnerabilities such as reentrancy attacks, integer overflows, and ensure gas optimization. Tools like MythX, Slither, and Truffle will be central to your audits.
Develop Automated Test Suites:
  • Build and maintain automated testing frameworks for smart contracts and blockchain systems. You’ll work with tools like Hardhat, Truffle, or Brownie to create continuous integration pipelines that automate functional, performance, and security testing.
Performance and Load Testing:
  • Conduct performance and load testing on blockchain networks to measure transaction throughput, latency, and overall system scalability. You’ll simulate high-traffic scenarios to ensure systems can handle large volumes of transactions efficiently.
Collaborate with Blockchain Developers:
  • Work closely with blockchain developers, smart contract engineers, and product teams to provide feedback on test results and collaborate on debugging and resolving issues. You’ll be involved early in the development cycle to ensure quality is built into the process from the start.
Security Testing and Vulnerability Assessments:
  • Perform security testing on blockchain applications, focusing on encryption protocols, key management, and decentralized data storage. You’ll assess systems for potential security vulnerabilities and recommend strategies to mitigate risks.
Monitor and Ensure Compliance with Industry Standards:
  • Ensure that blockchain solutions comply with industry standards and regulations, including data privacy laws, financial regulations, and security best practices. You’ll ensure that systems meet the legal and regulatory requirements of different markets.

Requirements

Required Skills:

  • Blockchain and Smart Contract Testing Expertise: Deep understanding of blockchain technology and smart contract systems, including hands-on experience testing decentralized applications on platforms like Ethereum, Hyperledger, or Binance Smart Chain.
  • Security and Auditing Knowledge: Experience conducting smart contract audits and security testing. You’re familiar with blockchain-specific vulnerabilities such as reentrancy attacks, underflows/overflows, and how to mitigate them.
  • Test Automation Skills: Proficiency in building automated testing frameworks using tools like Hardhat, Truffle, or Brownie. You know how to automate tests for functionality, performance, and security.
  • Performance Testing: Experience with performance testing of blockchain networks and decentralized applications. You can assess scalability and optimize systems for handling high transaction volumes.
  • Collaboration and Communication: Excellent collaboration skills, with the ability to work cross-functionally with developers, product managers, and business stakeholders. You can communicate test results and recommendations clearly.

Educational Requirements:

  • Bachelor’s or Master’s degree in Computer Science, Engineering, Blockchain Development, or a related field. Equivalent experience in blockchain quality assurance is also highly valued.
  • Certifications or additional coursework in blockchain technology, security testing, or quality engineering are a plus.

Experience Requirements:

  • 3+ years of experience in quality assurance or testing, with hands-on experience testing blockchain networks, smart contracts, or decentralized applications.
  • Proven experience with blockchain testing tools and frameworks such as Truffle, Hardhat, MythX, Slither, or Ganache.
  • Experience working with smart contract development tools and testing frameworks is highly desirable.

Benefits

  • Health and Wellness: Comprehensive medical, dental, and vision insurance plans with low co-pays and premiums.
  • Paid Time Off: Competitive vacation, sick leave, and 20 paid holidays per year.
  • Work-Life Balance: Flexible work schedules and telecommuting options.
  • Professional Development: Opportunities for training, certification reimbursement, and career advancement programs.
  • Wellness Programs: Access to wellness programs, including gym memberships, health screenings, and mental health resources.
  • Life and Disability Insurance: Life insurance and short-term/long-term disability coverage.
  • Employee Assistance Program (EAP): Confidential counseling and support services for personal and professional challenges.
  • Tuition Reimbursement: Financial assistance for continuing education and professional development.
  • Community Engagement: Opportunities to participate in community service and volunteer activities.
  • Recognition Programs: Employee recognition programs to celebrate achievements and milestones.
