Coinbase is seeking a Senior Blockchain Security Engineer to secure funds and data from protocols to wallets. You will be responsible for identifying security gaps, performing security assessments, and driving cross-functional efforts to secure Coinbase's interaction with blockchain technologies.
What You'll Do
- Identify gaps in our Crypto-Security infrastructure and drive cross-functional efforts to address them.
- Perform security assessments, framework development, and threat modeling of assets, including various blockchain protocols, smart contracts, and other distributed ledger tech.
- Partner with software engineering teams to advise on code and architecture for internal smart contract development.
- Partner with internal tooling teams to drive the roadmap and vision for internal Coinbase blockchain security tools.
- Identify automation opportunities in our tooling and processes, deliver a Proof of Concept, and write detailed technical requirements.
- Investigate impactful changes to the space, blockchain upgrades, and novel innovations such as zero-knowledge proofs and bleeding-edge blockchain protocols.
- Publish blogs and give talks (internal and external) on newfound vulnerabilities, incident investigations, unique integration risks, and related topics.
What We're Looking For
- Strong understanding of blockchains (particularly EVM chains) and highly 'crypto forward'.
- 4+ years of experience in security engineering, with significant focus on blockchain, distributed systems, or cryptographic infrastructure security.
- Extensive experience in architecture and threat modeling of security-critical backend crypto systems.
- Expertise in Application Security and cryptography, including applied knowledge of cryptographic primitives used in blockchain protocols (signing schemes, hash functions, zero-knowledge proofs, MPC).
- Familiar with all the fundamentals of onchain activity – blockchain explorers, funds tracing, bridging, DEXs, NFTs, smart contracts.
- Familiar with recent innovations such as restaking and the various EIPs currently being considered.
- Ability to provide leadership and mentorship to coworkers.
- Experience in a highly cross-functional role and/or leading a team.
- Excellence in clear, direct, and kind communication with technical and non-technical stakeholders, including the ability to translate complex security risks into actionable guidance for leadership.
- Experience with using AI/agentic tooling (Claude Code, Cursor, GPT Codex, etc.).
- Demonstrates the ability to responsibly use generative AI tools and copilots (e.g., LibreChat, Gemini, Glean) in daily workflows, continuously learn as tools evolve, and apply human-in-the-loop practices to deliver business-ready outputs and drive measurable improvements in efficiency, cost, and quality.
Nice to Have
