Secure mission delivery starts with strong engineering. Akima Data Management is hiring an Information System Security Engineer (ISSE) to design, engineer, and validate cybersecurity capabilities for Department of War (DoW) Office of Inspector General (OIG) information systems. The role supports alignment with federal, DoD, and organizational cybersecurity requirements across the system lifecycle, including continuous monitoring, to help strengthen protection and compliance.

What you’ll do

• Define, refine, and validate security requirements using mission objectives, threat assessments, risk analyses, and applicable cybersecurity policies, standards, and frameworks.
• Design and implement secure system architectures, data flows, and engineering solutions aligned with NIST, DoD, FedRAMP, and Zero Trust principles.
• Create security engineering artifacts including interface control documents and System Security Plans (SSPs), along with technical documentation supporting RMF authorization and accreditation activities.
• Perform security architecture reviews, threat modeling, vulnerability assessments, and security impact analyses across on-premises, cloud, and hybrid environments.
• Lead cloud vulnerability management, including scanning, assessment, prioritization, remediation tracking, and risk reporting across enterprise cloud platforms.
• Develop, review, and maintain cybersecurity policies, standards, procedures, and implementation guidance to support federal, DoD, and organizational compliance.
• Engineer and implement security controls and secure configurations using STIGs, SRGs, and baseline hardening requirements across systems, applications, cloud services, and networks.
• Conduct technical control assessments and security testing/validation to verify control effectiveness and reduce risk.
• Analyze findings, recommend risk-based mitigations, and support POA&M development, remediation management, and closure.
• Integrate security into the SDLC through secure coding, configuration management, and deployment practices.
• Assess security for system upgrades, patches, cloud migrations, integrations, and other infrastructure changes to identify and mitigate potential risks.
• Support continuous monitoring capabilities such as automated vulnerability scanning, logging, alerting, and security analytics.
• Provide technical support for incident response and forensic activities, including containment, eradication, and recovery operations.
• Evaluate emerging threats, vulnerabilities, cloud technologies, and adversary tactics to improve security posture and resilience.
• Translate security engineering requirements into actionable guidance for administrators, developers, architects, and operations teams.

What you’ll bring

• Active TOP SECRET with SCI clearance (required).
• Bachelor’s degree and 5–10 years of relevant experience, or 10+ years in lieu of a degree.
• IAM Level III certification required (examples: CGRC, CASP+ CE, CISSP, CISM). IAT Level III preferred.
• Strong understanding of NIST, FISMA, DoD, and organizational cybersecurity engineering frameworks.
• Experience with Vulnerability Management and policy writing.
• Experience with security architecture, RMF engineering, and secure system design.
• Strong communication, analytical, and documentation skills.

Security engineering tools and frameworks you’ll work with
