CACI is seeking a highly experienced and proactive Information Systems Security Officer (ISSO) to join our dynamic cybersecurity team supporting the U.S. Strategic Command (USSTRATCOM) Cybersecurity Service Provider (CSSP). This role aligns with the cybersecurity functions described in DoD 8140 Work Role ID 722 at the Advanced Level . The successful candidate will be responsible for the cybersecurity of assigned systems/enclaves, performing Risk Management Framework (RMF) and compliance activities (e.g., eMASS, ATO support), while also serving as a vital leader within the Vulnerability Management Orders and Directives (VMOD) team. In the VMOD capacity, this role is crucial for processing and disseminating threat intelligence to drive threat-based defense and for executing USSTRATCOM's vulnerability management program, working closely with the ISSM. This position may be subject to rotating shift work as necessary to support specific mission or incident response requirements.

The Opportunity:

Join a CACI team where the mission is critical, and the team culture is paramount. We are building a positive, fun, collaborative, and light-hearted environment focused on collective success and individual growth. Our leadership is committed to:

Culture: Fostering an engaging workplace through gamified cyber concepts (tabletop exercises, Backdoors & Breaches card game), team contests, informative lunch-and-learn sessions, active participation in local youth cyber programs, and opportunities to attend leading industry conventions like DEFCON and BSIDES. As a leader within the VMOD team, you will help drive this collaborative spirit.

Training: Championing life-long learning. We prioritize robust training programs aligned with your career goals and DoD requirements, focusing on RMF, threat intelligence analysis, vulnerability management, and leadership skills. Our leadership provides mentorship and resources, and you will contribute to the team's knowledge base.

Talent Management: Investing in your future. Every team member receives a detailed and fully customized Individual Development Plan (IDP). We facilitate cross-training and exploration of different roles within CACI, ensuring you remain challenged, engaged, and never bored. Your role offers a unique blend of compliance and operational security leadership.

This is more than just a job; it's an opportunity to significantly impact national security cyber defense through both compliance assurance and proactive threat/vulnerability management leadership within a supportive organization.

• Incident Response Support: Recognize potential security violations and take appropriate action to report incidents (KSAT 824). Support protective or corrective measures when incidents or vulnerabilities are discovered (KSAT 852).

• Stakeholder Collaboration & Communication: Collaborate extensively with the ISSM, SOC personnel, system administrators, and other internal/external stakeholders regarding threats, vulnerabilities, compliance status, and security improvements. Provide recommendations for tuning security controls/processes based on VMOD analysis and findings.

• Reporting: Collect and maintain data for VMOD and compliance reporting (KSAT 440). Ensure necessary reporting (e.g., threat summaries, vulnerability status, compliance issues) meets requirements, potentially including JFHQ-DODIN timelines per CJCSM 6510.01B.

Additional Duties: Perform other related duties as assigned by leadership to meet mission requirements and support USSTRATCOM objectives. Depending on experience and team structure, this role may involve working under direct supervision or potentially providing guidance, training, or supervision to others.
