Position: Senior Blockchain Security Engineer Location: Remote – Canada Type: Full-time Pay: $191,100 CAD + bonus + equity + benefits The Mission This role sits in Coinbase’s Protocol Security team — responsible for ensuring users interact safely with blockchain technologies. You’ll help secure L1s, L2s, DeFi protocols, staking mechanisms , and anything onchain. This isn’t just auditing smart contracts — it’s about leading security strategies , building tools and frameworks , and mentoring engineers to keep Coinbase and its customers safe as they expand into Web3. Threat Modeling & Security Assessments : Deep dive into new and existing onchain protocols to uncover risks. Strategy & Best Practices : Develop Coinbase-wide approaches to onchain security. Tooling & Frameworks : Contribute to or lead the development of security tooling for protocol assessments. Mentorship & Leadership : Guide junior security engineers; build a crypto-forward culture of learning. Cross-Team Collaboration : Interface with product and engineering teams to implement your findings into real-world security improvements. 3+ years of smart contract auditing and deep familiarity with vulnerabilities (e.g., reentrancy, MEV, oracle manipulation, etc.). Expert-level knowledge of blockchain ecosystems — Ethereum, Solana, L2s, DeFi, staking, etc. The ability to dissect machine-, transaction-, and logic-level issues . Leadership skills: You’ve led audits , mentored peers, and influenced security decisions at scale. Experience working closely with engineering/product teams in a collaborative, strategic way. A continuous learner’s mindset — crypto evolves fast, and you’re excited to evolve with it. Contributions to security tooling , open-source analysis frameworks , or industry security research . Familiarity with formal verification , fuzzing tools, or static analysis for smart contracts. Comfort working in high-stakes environments (like financial infrastructure or mission-critical apps). How to Position Yourself Here are some ideas to help tailor your resume, cover letter, or interview prep : Show off complex protocol audits you’ve led — include the protocol name if it’s public. Mention any tools or frameworks you’ve built or contributed to (even internally). Share your thought process on assessing risk at multiple layers : contract, protocol, business logic. If you’ve mentored or upskilled junior engineers in this space — highlight that leadership. Demonstrate a clear passion for the intersection of security and DeFi/Web3 . Why This Role Stands Out You shape the future of onchain security , not just react to issues. Work with one of the most security-forward crypto teams globally. Massive impact opportunity : your work will directly affect user safety and protocol trustworthiness. Coinbase pays competitively and offers great equity for top technical talent.
