• Lead and support activities in security planning, risk analysis, incident response, configuration control, and change management 

• Provide technical input and review of Certification & Accreditation (C&A) packages, including System Security Plans (SSPs), Risk Assessment Reports, and audit documentation 

• Apply your knowledge in system integration, intrusion detection, access control, cryptography (COTS/GOTS), and IA principles such as confidentiality, integrity, availability, and non-repudiation 

• Support security authorization processes in accordance with RMF, NISCAP, DIACAP, and Customer standards 

• Act as a key security engineering representative on multidisciplinary teams, guiding secure design and implementation across IA architectures, systems, and components 

• Collaborate with government stakeholders, project leads, and technical teams to ensure secure, compliant solutions at every step 

Whether you're designing solutions, identifying security gaps, or working alongside cross-functional teams, your contributions will be essential to ensuring mission readiness and data protection at the highest levels.
