About the role

Accenture Federal Services is looking for an Information System Security Officer (ISSO) to support the security, compliance, and risk management of cloud-based systems for the program.

• Continuous monitoring, vulnerability assessment, and risk analysis, including validating remediation actions and documenting POA&M updates
• RMF/JSIG documentation packages - SSP, SAP, SAR, POA&M, and continuous monitoring artifacts - supporting ATO and audit activities
• Security control implementation and compliance with STIG/CIS benchmarks and security authorization baselines
• Coordination with system administrators, security engineers, and DevOps teams on system changes that affect security posture, including Zero Trust Architecture requirements
• Incident handling and investigation of security anomalies, escalating and tracking recovery actions
• Audit log review and continuous monitoring tool analysis to identify anomalies, threats, and insider risk

What You'll Deliver

• Systems that maintain compliance with their security authorization package and ATO requirements
• Complete, audit-ready RMF documentation supporting authorization and assessment activities
• Timely identification, tracking, and remediation of vulnerabilities and security findings
• Documented incident response actions with verified restoration of affected controls
• A continuous monitoring program that measurably improves system security posture over time

Here's What You Need

• 3+ years of experience in an ISSO or equivalent security role - implementing security controls under RMF, JSIG, or ICD 503, using vulnerability management and SIEM tools (e.g., Nessus/ACAS, Splunk), and supporting cloud environments (AWS or Azure)
• DoD 8570 IAT Level II certification (e.g., Security+), or DoD 8140 equivalent
• Bachelor's degree in Computer Science, Information Systems, Engineering, or a related field, or 4+ years of relevant job or military experience in lieu of degree

Bonus Points If You Have

• DoD 8570 IAM Level II certification (e.g., CASP+, CISSP), or an AWS/Azure security certification
• Experience with STIG compliance tooling (SCAP Compliance Checker, Evaluate-STIG, eMASS) and DISA STIGs
• Experience with endpoint security platforms (Microsoft Defender, Trellix ePO) or a security incident response team (NOC/SOC)
• Familiarity with container security (Docker, Kubernetes, ECS/EKS/AKS)
