Jobs at Guardian in United Kingdom

Are you passionate about securing decentralized systems and safeguarding blockchain networks from vulnerabilities and attacks? Do you have a strong technical background in cryptography, cybersecurity, and blockchain technology? If you’re excited about ensuring the security of blockchain-based applications, smart contracts, and decentralized finance (DeFi) protocols, then our client has the perfect opportunity for you. We’re seeking a Blockchain Security Specialist (aka The Decentralized Guardian) to lead security efforts, protect decentralized ecosystems, and implement best practices to defend against threats in the blockchain space.

As a Blockchain Security Specialist at our client, you will collaborate with blockchain developers, smart contract engineers, and compliance teams to identify and mitigate security vulnerabilities in decentralized applications. You’ll be responsible for assessing risks, conducting security audits, and implementing robust security frameworks that ensure blockchain systems remain secure, transparent, and trustworthy.

Key Responsibilities:

1. Conduct Security Audits of Blockchain Systems: Perform detailed security audits of blockchain platforms, smart contracts, and decentralized applications (dApps) to identify vulnerabilities and recommend mitigation strategies. You’ll audit for common vulnerabilities like reentrancy attacks, front-running, integer overflows, and other blockchain-specific threats.
2. Develop and Implement Security Protocols: Design and implement security protocols that protect blockchain networks, consensus mechanisms, and smart contracts. You’ll work with encryption algorithms, secure key management systems, and decentralized authentication solutions to ensure maximum security.
3. Monitor and Respond to Security Threats: Continuously monitor blockchain systems for potential security breaches or attacks. You’ll implement real-time security monitoring tools and develop response protocols to minimize damage and mitigate risks in the event of an attack.
4. Collaborate on Smart Contract Security: Work closely with smart contract engineers to design secure smart contracts. You’ll ensure that contracts follow best practices for security, audit code before deployment, and use tools like MythX, Slither, or CertiK for vulnerability detection.
5. Ensure Compliance with Regulatory Standards: Ensure that blockchain systems comply with relevant security standards and regulations, such as GDPR, AML/KYC, and financial regulations. You’ll work with legal and compliance teams to ensure blockchain solutions meet industry security standards.
6. Implement Decentralized Key Management Solutions: Design and implement secure key management systems for decentralized networks, ensuring that cryptographic keys are stored and managed securely. You’ll work with multi-signature wallets, hardware wallets, and decentralized key management tools.
7. Stay Informed on Blockchain Security Trends: Keep up to date with the latest developments in blockchain security, including emerging threats, vulnerabilities, and new security tools. You’ll continuously experiment with new security protocols and contribute to developing cutting-edge security strategies.

Required Skills:

• Blockchain Security Expertise: Extensive experience in blockchain security, including knowledge of cryptographic protocols, smart contract vulnerabilities, consensus algorithms, and attack vectors unique to decentralized networks.
• Smart Contract Auditing: Strong understanding of smart contract auditing tools and techniques, including experience with tools like MythX, Slither, CertiK, or OpenZeppelin. You know how to identify and mitigate vulnerabilities in smart contracts.
• Cryptography and Key Management: Expertise in cryptographic algorithms and secure key management systems. You’re experienced with encryption techniques, multi-signature wallets, and decentralized authentication protocols.
• Threat Detection and Incident Response: Experience in monitoring blockchain networks for security threats and implementing response protocols. You’re familiar with threat detection tools and can react swiftly to potential security breaches.
• Collaboration and Communication: Strong collaboration skills, with the ability to work closely with developers, product managers, and compliance teams. You can communicate complex security concepts to both technical and non-technical stakeholders.

Educational Requirements:

• Bachelor’s or Master’s degree in Computer Science, Cybersecurity, Blockchain, Cryptography, or a related field. Equivalent experience in blockchain security is highly valued.
• Certifications such as Certified Blockchain Security Professional (CBSP) or Certified Information Systems Security Professional (CISSP) are a plus.

Experience Requirements:

• 3+ years of experience in blockchain security, with hands-on experience securing decentralized systems and auditing smart contracts.
• Proven track record of identifying vulnerabilities in blockchain platforms and implementing security protocols to mitigate risks.
• Experience working with decentralized systems, cryptographic protocols, and blockchain platforms such as Ethereum, Binance Smart Chain, or Solana is highly desirable.
