Senior Information Systems Security Officer

ABOUT THE TEAM

The Connected Warfare division builds systems to support global command and control missions. We create joint, time-sensitive, multi-domain, ubiquitous, connected mesh ecosystems. Our ecosystem enables connected warfare with disproportional impact by connecting every robot, human, and sensor in every domain, bringing together hundreds of thousands of end points across the globe. We are the substrate that provides the source of truth for time-sensitive decisions, effectively transforming the way that militaries close kill chains and enable mission autonomy.

ABOUT THE JOB

As the ISSO for a large-scale Army Command & Control (C2) program, you will serve as the hands-on security practitioner responsible for day-to-day compliance execution and vulnerability management across a cloud-native platform. You'll work directly under the ISSM to manage CVE remediation workflows, review third-party vendor security artifacts, maintain authorization documentation in eMASS, and enforce continuous monitoring across multiple environments running on a Kubernetes-based PaaS.

WHAT YOU'LL DO

• Track and coordinate CVE remediation across all program environments using automated container vulnerability scanning, enforcing SLA timelines with owning engineering teams
• Review third-party vendor onboarding security packages: container scan results, SAST reports, CSSP audit logging documents, POA&Ms, SBOMs, STIG checklists, and network/data flow diagrams
• Validate STIG compliance using SCAP, Evaluate-STIG, and review against DISA STIGs for containerized applications and Kubernetes infrastructure
• Manage and audit user access controls through the platform's role-based permission model, enforcing least privilege and RBAC across all environments
• Monitor security events through coordination with the program's Cybersecurity Service Provider (CSSP), which runs 24/7 monitoring; review audit logs, investigate anomalies, and escalate per incident response procedures
• Maintain all security artifacts in eMASS including POA&Ms, risk assessments, authorization letters, and continuous monitoring evidence across multiple eMASS records
• Review platform Change Requests for security impact
• Support RMF activities including security control assessments, SCA evidence collection, and ATO package preparation
• Conduct weekly CVE expiry reviews, compile per-team remediation lists, and coordinate bulk outreach to engineering teams
• Assist with ISA development and review for system interconnections and Cross-Domain Solution paths

• Experience with vulnerability scanning tools and CVE remediation tracking workflows
• Experience managing user access controls and conducting account/access reviews
• Currently possesses and is able to maintain an active U.S. Secret security clearance

PREFERRED QUALIFICATIONS

• Experience with container security scanning (Trivy, Grype, or similar) in Kubernetes environments
• Familiarity with cloud PaaS platforms in a DoD context (IL2 through IL6)
• Experience with eMASS for RMF package management and continuous monitoring
• Hands-on experience reviewing third-party vendor security artifacts (SBOMs, SAST/DAST reports, POA&Ms) for onboarding decisions
• Familiarity with Cross-Domain Solutions and multi-enclave environments
