Information System Security Manager (ISSM) - Cloud Security Architect

Position Summary

This role is ideal for a hands-on cloud security engineer first, policy-aware second. You will actively engineer and enforce security controls across cloud and hybrid environments while maintaining RMF/ATO governance, continuous monitoring, and compliance. Expect roughly 66% platform engineering (secure design/implementation, automation, remediation) and 33% governance/policy enforcement (RMF artifacts, POA&Ms, attestations, board cadence).

Core Responsibilities

Governance, RMF & Compliance
  • Lead RMF/ATO/ATC activities: develop and maintain SSP, control implementations, evidence, POA&Ms, and continuous monitoring strategy; coordinate with Government ISSO, SCV, AO; sustain ATO per USAF guidance.
  • Enforce DISA STIG/SRG configurations across enterprise hardware/software; ensure timely patching/bug-fix deployment and flaw remediation with documented procedures.
  • Enable and manage ACAS/Nessus vulnerability scanning (external and internal), deliver bi-weekly/30-day reports, and drive remediation to closure.
  • Support incident response: immediate notification (phone/email) within six hours of discovery; 30-day follow-up reporting; maintain secure audit logs and event evidence.
  • Participate in PMRs and CCBs; maintain enterprise baseline and CM Plan; provide artifacts (topologies, inventories, rack elevations, ports/protocols) and read-only visibility to Government tools/portals.

Cloud Security Architecture
  • Implement secure configurations in AWS, Azure, GCP (or comparable platforms).
  • Engineer IAM: RBAC, least-privilege, multi-account strategy, federation (IdP integration).
  • Configure cloud-native logging/monitoring/alerting for security visibility (e.g., provider equivalents to CloudWatch).
  • Apply Zero-Trust principles across cloud networking and service-to-service comms (authN/authZ, encryption, segmentation).
  • Develop IaC security baselines; codify guardrails/policies; enforce drift detection.

Vulnerability Management & Compliance
  • Operate ACAS and vulnerability scanners; analyze findings; prioritize remediation; validate fixes; sustain POA&Ms and compliance dashboards (NIST SP 800-53, DISA STIGs, CMMC as applicable).
  • Produce traceability mapping of technical controls to required frameworks; prepare audit evidence and assessor packages.

Platform Security (Linux, Windows, Virtualization)
  • Linux (≈70%): hardening, auditing, patching, secure configuration, STIG application/validation.
  • Windows (≈30%): server security configuration, patch management, policy baselines.
  • Virtualization: secure VMs and management planes (e.g., VMware), including isolation, logging, and role segmentation.

Kubernetes & Container Security
  • Secure clusters: RBAC, network policies, secrets management, pod security standards; image signing and vulnerability scanning; protect service meshes and encrypted service communication.

Networking & Zero Trust
  • Apply TCP/IP, firewalls, VLANs, VPNs, routing, micro-segmentation to enforce least-privilege access across hybrid environments; integrate CoS/QoS and performance KPIs where applicable.

Automation & DevSecOps
  • Bash/Python automation for remediation and control validation.
  • Terraform/Ansible (or equivalent) for enforcing baselines, policy-as-code, and repeatable secure deployments.
  • CI/CD security integration, pre-deployment testing, and lab validation prior to production changes.

Collaboration & Leadership
  • Serve as trusted advisor to COR and Government Technical Leads; brief diverse stakeholders in clear, mission-focused terms.
  • Coordinate with PM, architects, network engineers, helpdesk/T3, and cybersecurity analysts; maintain cadence with PMRs and escalation SOPs.
