Information Systems Security Manager; ISSM

Ready to make connectivity from space universally accessible, secure and actionable? Then you’ve come to the right place!

E-Space is bridging Earth and space to enable hyper-scaled deployments of Internet of Things (IoT) solutions and services. We are building a highly-advanced low Earth orbit (LEO) space system that will fundamentally change the design, economics, manufacturing and service delivery associated with traditional satellite and terrestrial IoT systems.

We’re intentional, we’re unapologetically curious and we’re 100% committed to innovate space-based communications and deliver actionable intelligence that will expand global economies, protect space and our planet and enhance our overall quality of life.

The Information Systems Security Manager (ISSM) serves as the primary authority responsible for the cybersecurity posture and compliance of all classified information systems operating within a Top Secret possessing facility under a Department of Defense (DoD) Facility Clearance (FCL). This role is pivotal in ensuring the organization meets all requirements set forth by the National Industrial Security Program Operating Manual (NISPOM), the Defense Counterintelligence and Security Agency (DCSA), and applicable Intelligence Community Directives (ICDs).

The ISSM will serve as the authoritative point of contact to the Cognizant Security Authority (CSA) and Government Contracting Activity (GCA) for all matters relating to the authorization, operation, and continuous monitoring of classified information systems, including Sensitive Compartmented Information (SCI) systems where applicable

• Conduct periodic self-inspections of classified IS programs and remediate findings in coordination with the FSO and program leadership.

Continuous Monitoring & Incident Response

• Implement and manage a Continuous Monitoring (Con Mon) program for all authorized classified information systems.
• Monitor audit logs, SIEM alerts, and vulnerability scan results; investigate anomalies and potential insider threats.
• Serve as the Facility Incident Response Manager for classified information system security incidents; coordinate reporting to DCSA and GCAs within required time frames.
• Conduct or oversee technical vulnerability assessments and penetration testing as required by the CSA or contract requirements.

Personnel Security & Training

• Oversee ISSM-delegated Information System Security Officer (ISSO) personnel; provide mentorship, task delegation, and performance oversight.
• Develop and deliver annual IS security awareness training and role-based training for users of classified information systems.
• Maintain personnel access records and access control lists (ACLs) for all classified IS; ensure need-to-know verification prior to system access grants.
