Job Description
As a blockchain security specialist, you will be responsible for conducting in-depth security assessments and threat modeling across diverse blockchain protocols and smart contract ecosystems. This role involves identifying critical security risks within decentralized systems, analyzing their potential impact, and developing robust strategies to mitigate vulnerabilities. You will also collaborate with cross-functional teams to design and implement innovative security frameworks, analysis tools, and products that enhance the overall resilience of blockchain platforms. Additionally, you will establish and promote best practices for blockchain security, ensuring their integration into product development and engineering workflows through continuous engagement and knowledge sharing.
Key Responsibilities
- Perform comprehensive security assessments of blockchain protocols and smart contracts to detect vulnerabilities, logical flaws, and potential attack vectors through code audits, penetration testing, and protocol analysis.
- Develop threat models for blockchain architectures, evaluating security risks such as consensus failures, transaction malleability, and smart contract exploits, and proposing actionable mitigation strategies.
- Collaborate with developers, product managers, and engineers to design and implement new security frameworks, analysis tools, and products that address emerging threats and improve system robustness.
- Establish and document best practices for blockchain security, including secure coding standards, cryptographic protocols, and decentralized application (dApp) security guidelines, to ensure adoption across teams.
- Conduct regular risk assessments to prioritize security threats based on their severity, likelihood of exploitation, and potential impact on user assets or network integrity.
- Engage with stakeholders to communicate security findings, recommend improvements, and ensure alignment between security protocols and business objectives.
Job Requirements
- Minimum of 3 years of hands-on experience in blockchain security, with a proven track record in smart contract audits, protocol analysis, and threat modeling for decentralized systems.
- Strong technical expertise in blockchain technologies, including consensus mechanisms, cryptographic algorithms, and smart contract development frameworks such as Solidity, Vyper, or Rust.
- Proficiency in security tools and methodologies, including static code analysis, dynamic testing, and penetration testing for blockchain applications and protocols.
- Excellent problem-solving skills to analyze complex security challenges, identify root causes, and design scalable solutions for blockchain ecosystems.
- Ability to work independently and collaboratively with cross-functional teams to integrate security practices into product development cycles and engineering standards.
- Preferred experience with blockchain platforms such as Ethereum, Hyperledger, or Polkadot, and familiarity with security frameworks like OWASP, NIST, or ISO 27001.
- Strong communication skills to present technical findings to non-technical stakeholders and document security strategies for internal and external use.
- Knowledge of decentralized finance (DeFi) security, tokenomics, and smart contract interaction patterns to address specific risk scenarios in blockchain projects.
- Experience with automation tools for security testing, including writing scripts for vulnerability scanning, monitoring network behavior, and analyzing transaction patterns.
- Ability to stay updated with the latest blockchain security threats, research, and industry trends to continuously improve security strategies and frameworks.
