Chief Information Security Officer (GAOH164)
About the Role
The Chief Information Security Officer (CISO) is the executive leader responsible for Defense Unicorns' enterprise-wide information technology and security strategy, governance, and risk posture. Reporting directly to the CEO and working in close partnership with senior leadership, the CISO owns the full security function, including direct oversight of the Director of Security Compliance and the Director of Information Technology.
This is a mission-critical leadership role at the intersection of national security, defense technology, and enterprise IT. The CISO ensures that Defense Unicorns can pursue and execute DoD and federal contracts confidently, with a security program that is not only audit-ready but genuinely resilient. Equally, the CISO provides executive direction over the information technology function, overseeing corporate infrastructure, systems, networks, and the technology platforms that enable our Unicorns to operate effectively and securely at scale. The right person brings both the technical credibility to earn trust with engineers and operators, and the executive presence to advise leadership and represent the company's security and technology posture to customers, partners, and government stakeholders.
As the organization scales, the CISO will be the architect of a security culture that is embedded, not bolted on, enabling the mission rather than impeding it. This commitment to “The Unicorn Experience” is non-negotiable. This means not only governing risk and compliance, but ensuring the IT foundation beneath the business is modern, resilient, and capable of supporting a fast-growing defense technology company operating in highly sensitive environments. This dual ownership of security and IT is intentional: at Defense Unicorns, protecting the mission and enabling the workforce are not separate problems, they require a unified leader who can hold both.
