• Develop automation that reduces manual effort, improves consistency, accelerates response, and provides measurable operational benefits.
• Support enterprise vulnerability management by identifying technical risks, assisting system owners with remediation, validating corrective actions, and recommending compensating controls when remediation cannot be completed promptly.
• Develop and implement secure configuration standards, technical security baselines, reference architectures, and reusable engineering patterns.
• Participate in security architecture and technical design reviews for enterprise systems, applications, cloud services, and infrastructure changes.
• Evaluate proposed technologies and system changes to identify security requirements, integration dependencies, technical risks, and operational support requirements.

• Identify gaps in security visibility, platform coverage, system configuration, integration, and technical control effectiveness, and develop practical corrective actions.
• Plan, test, document, and implement security-related changes in accordance with established change-management requirements, including validation and rollback procedures.
• Monitor the operational health, capacity, licensing, support status, and effectiveness of assigned security platforms.
• Maintain accurate technical documentation, including architecture diagrams, configuration records, integration specifications, runbooks, operating procedures, and troubleshooting guides.
• Cross-train other team members and develop documentation that reduces reliance on individual personnel for critical security technologies and processes.
• Coordinate with vendors and service providers to resolve technical issues, evaluate product capabilities, and plan upgrades or improvements.
