• Engineer core security solutions (boundary protection, encryption, IAM, auditing, secure configs).
• Embed security across the full system lifecycle-requirements through sustainment.
• Develop and maintain A&A documentation and support ATO evidence.
• Test and verify security controls across applications, platforms, and networks.
• Conduct risk assessments, threat modeling, and vulnerability analysis; recommend mitigations.
• Assess security impacts of system changes, upgrades, and new integrations.
• Apply DISA STIGs, CIS Benchmarks, and maintain hardened configuration baselines.
• Design monitoring architectures for SIEM, detection rules, and audit/log collection.
• Support incident response with architectural forensics and remediation guidance.
• Collaborate with developers, integrators, administrators, and cybersecurity teams.
• Present security engineering findings and architecture recommendations to leadership.
• Produce technical documentation, diagrams, reports, SOPs, and design artifacts.
