This is not a listing for an internal role at Dragonfly. This posting connects you directly with one or more of our portfolio companies actively hiring Security Engineers.
What We’re Looking For
- 2–5 years of experience in security engineering, operations, or infrastructure security, ideally across both cloud and crypto-native environments.
- Solid understanding of application, network, and blockchain security principles.
- Hands-on experience with SIEMs, EDR tools, or threat detection systems.
- Familiarity with GCP, AWS, or other production cloud environments, as well as containerized or distributed systems.
- Understanding of web3 security concepts such as multisig wallets, smart contract risks, validator security, and key management.
- Experience building or operating automated security monitoring and alerting pipelines.
- Strong scripting or automation skills (Python, TypeScript, or Go).
- Bonus: experience with security audits, compliance frameworks (SOC 2, ISO 27001, NIST CSF), or open-source security tools.
About the Role(s)
Our portfolio companies are hiring across two main focus areas:
Infrastructure-Focused Roles
- Secure and monitor blockchain infrastructure, nodes, and validators.
- Build and maintain security tooling for on-chain infrastructure, RPC endpoints, and key management systems.
- Harden cloud and network environments, implement defense-in-depth for production systems, and manage secrets and access control.
- Respond to infrastructure-level threats, analyze incidents, and improve detection coverage.
Application-Focused Roles
- Partner with smart contract and product teams to secure DeFi, wallet, or protocol codebases.
- Contribute to application-level threat modeling, auditing, and secure development practices.
- Develop internal tooling for vulnerability scanning, dependency management, and transaction monitoring.
- Work with on-chain analytics and incident response for protocol or user-level exploits.
- Even if you don’t match every point but are passionate about security in crypto, we encourage you to apply.
Process
- We’ll confidentially match you with portfolio companies aligned with your background, skill set, and interests.
- If mutual interest exists, we’ll facilitate a warm introduction.
- If there isn’t a match today, we’ll keep you top of mind for future opportunities.
All candidate submissions are strictly confidential.
