Possess a DoD 8140 Intermediate certification (e.g., Cloud+, Security+, etc.). Experience in system security engineering, risk management, and vulnerability assessments. Strong grasp of network security concepts, security controls, and prevalent cybersecurity tools (e.g., firewalls, IDS/IPS, SIEM, endpoint protection). Ability to work independently while collaborating effectively with diverse teams. Excellent communication skills, including proficiency in creating and presenting detailed security reports to various stakeholders. A genuine interest in continuous learning and professional growth in cybersecurity. Preferred Qualifications: DoD 8140 Advanced certification (e.g., CISSP, CISM, etc.). Experience with the Risk Management Framework (RMF) for DoD system accreditations and in implementing continuous monitoring processes. Previous experience managing security for complex DoD programs or mission-critical systems. Familiarity with cloud security practices and systems, particularly in hybrid or government cloud environments. Experience with security tools for vulnerability scanning, penetration testing, and auditing. Cloud security certifications (e.g., Azure Security Technologies or AWS Certified Security Specialty). Experience with configuration and change management within a secure environment. At Leidos, we seek individuals who think outside the box and are driven to innovate.
