• Manage security infrastructure projects from planning to deployment while ensuring compliance with internal policies and risk requirements.
• Translate security and compliance requirements into secure systems configurations, encryption protocols, and access controls.
• Implement system hardening standards and technical baselines to reduce security vulnerabilities and cyber risks.
• Develop automation scripts and platform integrations to improve data flow, automate health checks, and streamline security system management.
