Blockchain Security Researcher

This position is listed on behalf of a partner company, who manages all applications and next steps. Our partner is looking for a Blockchain Security Researcher based in Canada.

Join a globally distributed security research team dedicated to protecting the next generation of blockchain applications and digital financial infrastructure. As a Blockchain Security Researcher, you will help secure decentralized applications, smart contracts, and onchain financial systems used by leading organizations worldwide. You will conduct in-depth security audits, identify critical vulnerabilities, and collaborate with engineering teams to strengthen protocol architectures before and after launch.

Working independently and alongside other researchers, you will leverage AI-powered tools to expand audit coverage, streamline workflows, and improve research outcomes. You will also investigate emerging attack vectors and contribute to the broader blockchain security ecosystem. This remote opportunity is ideal for a technically curious researcher passionate about smart contract development, innovative security methodologies, and advancing decentralized finance.

• Conduct comprehensive security audits of smart contracts used by decentralized applications, blockchain infrastructure, and financial institutions, identifying vulnerabilities, assessing their severity, and presenting actionable findings to clients.
• Lead security audits independently from planning through final reporting, using AI as a core research collaborator and partnering with other researchers when additional technical perspectives are valuable.
• Participate in protocol design reviews and applied research engagements, evaluating system architecture, trust assumptions, threat models, and operational constraints before implementation begins.
• Collaborate with client engineering teams to analyze, design, specify, and improve smart contract mechanisms and security-critical protocol components.
• Integrate AI tools throughout the audit lifecycle to improve coverage, accelerate complex reasoning, and enhance the quality and efficiency of research deliverables.
• Develop and maintain reusable security tooling, including AI agents, prompts, scripts, and automated workflows that can be adopted and extended by the wider research team.
• Investigate emerging blockchain technologies, vulnerability classes, exploit techniques, and attack vectors to identify risks in evolving onchain systems.
• Document research findings, communicate technical risks clearly to clients, and contribute insights to internal security knowledge bases and the broader blockchain ecosystem.
• Continuously refine audit methodologies and research practices to address new threats and improve smart contract security standards.

• Practical experience in one or more relevant technical fields, including software development, cybersecurity, applied mathematics, distributed systems, cryptography, cryptoeconomics, game theory, or decentralized finance mechanisms.
• Hands-on experience designing and developing smart contracts, beyond reviewing or auditing existing implementations.
• Strong working knowledge of Solidity and the Ethereum Virtual Machine (EVM) ecosystem, including common libraries, development frameworks, smart contract patterns, and protocol architectures.
• Regular, effective use of modern AI tools to improve security audits, reason about complex systems, expand vulnerability coverage, and produce high-quality technical outputs.
• Ability to critically evaluate AI-generated code and findings, identify potential inaccuracies, and apply sound security judgment rather than relying on automated outputs without verification.
• Experience building or extending technical tools and workflows,…
