Blockchain Security Researcher

Responsibilities

• Review smart contracts for top decentralized applications, blockchain infrastructure and financial institutions before they launch. Find vulnerabilities, prioritize them, and present findings to the client.
• Drive audits independently from start to finish, with AI as your primary collaborator. When useful, partner with another researcher to attack the code together and pressure-test findings.
• Partner with client teams during the design phase of new protocols, analyzing architecture, trust assumptions, and operational constraints before any code is written (Design Reviews, Applied
• Research engagements).
• Use AI efficiently throughout the audit process, and build skills, agents, and workflows that compound across the team.
• Conduct open-ended research into cutting-edge blockchain technologies, vulnerability classes, and emerging attack vectors, and contribute findings back to OpenZeppelin's internal knowledge base and to the broader ecosystem.
• Hands-on and practical experience in one or more of the following: software development, cybersecurity, applied mathematics, distributed systems, cryptography, cryptoeconomics or game theory, or DeFi mechanisms.
• Experience designing and developing smart contracts, not only auditing them.
• Strong working knowledge of Solidity and the broader Ethereum / EVM ecosystem (common libraries, frameworks, smart contract patterns).
• Modern AI tooling is central to how you work, not a novelty. You use it daily to expand audit coverage, reason about complex systems, and produce high-quality outputs faster. You evaluate AI-generated code with a critical eye.
