Who You Are
The Blockchain Security Lead owns the security posture of on-chain systems and protocols across the organization. This role blends strategic leadership with deep hands-on expertise, overseeing a small team of blockchain security engineers while actively contributing to design reviews, threat modeling, and code audits.
You’ll partner closely with on-chain product and engineering teams to embed security into architecture, development, and operations—building scalable, reusable security controls that grow with the business.
What You’ll Do
- Lead, mentor, and grow a team of blockchain security engineers.
- Define and evolve the blockchain security strategy and roadmap.
- Serve as a trusted security partner to product, protocol, and infrastructure teams.
- Lead threat modeling and architecture reviews for on-chain systems.
- Perform and guide security reviews and audits of smart contracts (Solidity, Rust/Solana) and backend services and supporting infrastructure.
- Design and implement reusable security controls, patterns, and reference architectures.
- Support secure deployment of cloud-native infrastructure (containers, Kubernetes).
- Research emerging blockchain threats, exploits, and mitigations, and translate them into actionable controls.
- Embrace and champion the thoughtful adoption of AI to improve team performance and business outcomes.
- Leverage AI tools (e.g., generative AI, automation platforms, data copilots) to improve productivity, decision-making, and output quality in your day-to-day work.
What We’re Looking For
- Bachelor’s degree in Computer Science, Engineering, or a related field (or equivalent experience)
- 10+ years of security software engineering experience
- 5+ years working with blockchain technologies
- 5+ years working with smart contract security across multiple chains
- Experience leading or mentoring a small, highly technical team
- Published material on vulnerabilities/security bugs within the Web3 community
- Expertise in secure SDLC, threat modeling, and application architecture review
- Multi agent code reviews for vulnerabilities using frontier models
- Secure coding practices and in-depth code review capability
- Strong familiarity with smart contracts (Solidity, Rust), cloud-native environments (Docker, Kubernetes), authentication and authorization, TLS/PKI, and cloud, infrastructure, and network security
- Clear, confident communicator across technical and non-technical audiences
- Comfortable balancing hands-on execution with strategic ownership; detail-oriented, pragmatic, and strong in problem solving under ambiguity
Bonus Points
- Direct exposure to Solana, staking systems, or similar Layer 1 protocols
- Prior experience at a blockchain security audit firm (e.g., Trail of Bits, Halborn, Ottersec, Zellic)
- Background in financial services or institutional crypto security
- Familiarity with DeFi protocol security, key management, and custody architectures
- Experience contributing to or leading security programs at a crypto exchange, protocol foundation, or digital asset firm
