Job Description

Dragonfly is a crypto-native Venture Capital and research firm with $3.6B+ in assets under management and 160+ portfolio companies. Our Talent team connects people with roles across our portfolio, opening the door to opportunities through our Talent Network.

This is not a listing for an internal role at Dragonfly. This posting connects you directly with one of our portfolio companies, which is looking to bring on a Head of Security to lead all aspects of cybersecurity, blockchain security, and operational risk management for a next-generation digital dollar platform bridging DeFi and traditional finance.

What We're Looking For:
  • 10+ years of experience in security leadership roles, with deep expertise in cybersecurity, blockchain, and risk management
  • Proven ability to design and execute holistic security programs across digital and physical domains
  • Strong understanding of blockchain and DeFi security (smart contract auditing, key management, exploit mitigation)
  • Experience with compliance and certification frameworks (SOC 2, ISO 27001, GDPR, AML/KYC)
  • Demonstrated leadership in building and mentoring high-performing security teams
  • Technical proficiency across cloud infrastructure (AWS, GCP, Kubernetes), secure software development, and monitoring systems
  • Bachelor’s or Master’s degree in Computer Science, Information Security, or related field; certifications like CISSP, CISM, or CRISC preferred
  • Familiarity with DeFi-specific risks and security design patterns is a strong plus

About the Role:
You will own the company’s global security strategy, spanning cybersecurity, blockchain security, physical security, and operational protection. Working closely with engineering, product, and compliance teams, you’ll embed security-by-design across all systems and processes.

Key responsibilities include:
  • Developing and executing a comprehensive security framework aligned with NIST and ISO 27001.
  • Leading blockchain and smart contract security, including audits, formal verification, and exploit prevention
  • Managing incident response, threat detection, and vulnerability management programs
  • Driving compliance readiness for SOC 2 and ISO 27001 certifications
  • Overseeing physical security, executive protection, and operational risk mitigation
  • Building and mentoring a multidisciplinary security team
  • Cultivating a culture of proactive risk management across the organization
  • This is a high-impact leadership role in a fast-scaling environment where DeFi innovation meets real-world financial infrastructure

Process:
  • We’ll confidentially match you with portfolio companies aligned with your background, skill set, and interests
  • If mutual interest exists between you and a team, we’ll facilitate a warm introduction
  • If there isn’t a match today, we’ll keep you top of mind for future opportunities

Our portfolio companies are globally distributed, offering remote, hybrid, and in-person roles worldwide. They’re building across the entire crypto ecosystem—including Crypto x AI, Prediction Markets, DeFi, CeFi, infrastructure, L1S and L2S, creator/consumer applications, NFTs, ZK, and more. All candidate submissions are strictly confidential.
