ECCOS Program Manager II

The Cyber Security Engineer II (Senior) serves as NetSEA's primary technical liaison between the ECCOS CSSP team and Mission Delta 6 system owners. This role owns cybersecurity alignment activities across Mission Delta 6's space mission enterprise – coordinating Service Level Agreements, driving the CSSP Working Group, and ensuring system owners have a clear, proactive path to compliance rather than a reactive one.

This is a senior, client-facing technical role requiring both deep cybersecurity engineering expertise and the judgment to operate as a trusted advisor to Government stakeholders.

• Serve as the primary System Owner interface for cybersecurity alignment activities across Mission Delta 6 space systems at Schriever SFB, Peterson SFB, and the Colorado Springs local area
• Coordinate Service Level Agreements (SLAs) between the CSSP team and system owners, tracking status and escalating at-risk items before they become findings
• Participate in and help drive the CSSP Working Group, surfacing and resolving cybersecurity alignment issues at the working level
• Develop and maintain the Cybersecurity Alignment Plan and supporting compliance documentation
• Apply Zero Trust Architecture principles to cybersecurity alignment across enterprise and space-adjacent network segments (User, Ground, and Space Segments)
• Support eMASS/RMF lifecycle documentation, including SSPs, SARs, and POA&M control-to-evidence mapping
• Provide technical mentorship and day-to-day direction to Analyst-level CSSP team members
• Represent NetSEA in technical discussions and status reviews with the Government Program Manager (GPM) and COR
• Support the Contingency Operations Plan and mission essential coverage requirements as a Tier 1 role

• Bachelor's degree in Computer Science, Cybersecurity, Information Systems, or a related field, or equivalent experience
• 10+ years of relevant cybersecurity and/or network engineering experience, including experience in DoD or federal environments
• Active DoD 8140-aligned certification appropriate to a CSSP Analyst/Infrastructure Support work role (e.g., CISSP, GCIH, CASP+, or equivalent)
• Active Top Secret clearance with SCI eligibility, or an active Secret clearance with a submitted SSBI/Tier 5 investigation and the ability to reach TS/SCI eligibility within approximately 90 days
• Demonstrated experience with RMF/ATO processes, eMASS, and DoD cybersecurity compliance frameworks

• Prior experience supporting a CSSP (Cybersecurity Service Provider) mission specifically, rather than general IA/cybersecurity support
• Prior experience supporting U.S. Space Force, Space Delta, or other space mission enterprise programs
• Experience with Zero Trust Architecture implementation or assessment
• Prior experience in a client-facing technical lead or working-group chair role
• Familiarity with SATCOM or space-adjacent network segment security

• Strong working knowledge of NIST SP 800-53, NIST SP 800-171,…
