Lead Security Engineer - Information Systems Security Manager (ISSM)

Stratolaunch is a technology accelerator that engineers operationally realistic testing at Mach 5+. Our air-launched, Talon testbeds are reusable, cost-effective platforms that enable routine access to the hypersonic environment. We deliver flight data critical to validating system performance and achieving rapid technology deployment. Together with our customers, we drive innovations that are imperative to advancing national security.

We are seeking a Lead Security Engineer - Information Systems Security Manager (ISSM) to lead the cybersecurity authorization, operation, and continuous monitoring of classified information systems supporting our hypersonic programs and advanced engineering capabilities.

This is a hands-on technical security role. The ISSM will serve as the primary cybersecurity authority for classified information systems and will work closely with Information Security, IT, Industrial Security, Engineering, Program Management, and government stakeholders to build secure classified computing environments that enable mission execution.

The ideal candidate combines practical IT and security engineering experience with a strong understanding of the Risk Management Framework and is comfortable owning a classified system throughout its full lifecycle, from architecture and authorization through operations, continuous monitoring, and eventual decommissioning.

This is a senior individual-contributor position with significant technical ownership and the opportunity to help shape the company's classified cybersecurity program as it grows.

• Partner with IT and Engineering to design, build, secure, and operate classified computing environments.
• Support the implementation and accreditation requirements associated with SIPRNet connectivity.
• Establish secure configuration baselines based on applicable DISA STIGs and government guidance.
• Partner with Program Managers and engineering teams to understand classified computing requirements early in the program lifecycle.
• Develop scalable standards, procedures, templates, and technical baselines for classified information systems.
• Coordinate closely with the Facility Security Officer (FSO) and Industrial Security team on matters involving classified information, personnel access, physical security, and security incidents.
• Support the Insider Threat Program as it relates to classified information-system activity and cybersecurity.
• Provide cybersecurity training and technical guidance to system administrators, engineers, ISSOs, and classified-system users.
• Mentor or provide technical direction to future Information Systems Security Officers (ISSOs) as the classified environment expands.

• Ability to communicate effectively with engineers, system administrators, program managers, security professionals, government representatives, and executive stakeholders.
• Active U.S. Secret security clearance or higher.
• Ability to obtain and maintain a Top Secret clearance and additional program accesses as required.
• Ability to work onsite due to the nature of the classified systems and responsibilities associated with the position.
• Relevant cybersecurity certification such as Security+, CISSP, CISM, or equivalent.
• Experience with security compliance frameworks and standards such as DAAPM, NISPOM, JSIG, ICD 503, NIST 800-53, and NIST 800-171.
