Responsibilities

• Security Control & Evergreening: Maintain, upgrade, and optimize enterprise network security controls, ensuring the environment is continuously modernized and simplified.
• Vulnerability & Risk Mitigation: Diagnose, mitigate, and resolve complex, cross-functional network security risks, operational issues, and emerging threats across production and non-production environments.
• Incident Response & Monitoring: Monitor and analyze network security events leveraging logs, alerts, and enterprise monitoring tools to identify root causes and recommend decisive remediation actions.

• Intelligent Automation: Research, recommend, and implement automation best practices to eliminate repetitive tasks and significantly improve operational efficiency.
• Collaboration & Compliance: Partner with internal teams to ensure all network solutions strictly adhere to security policies, industry standards, and regulatory banking requirements.

• Dual Expertise: 5+ years of recent, demonstrated experience blending core Network Operations with robust Network Security (testing, troubleshooting, and enterprise integration).
• The Core Tech Stack: 5+ years of hands-on experience with Cisco switching and routing platforms AND Check Point firewall technologies & security management platforms.
• IT Operations & Triage: Strong knowledge of incident response, vulnerability handling, and managing security controls (such as micro-segmentation policies and secure configurations).
• Modern Workflows: Demonstrated ability to support continuous integration and continuous deployment (CI/CD) processes throughout the full development lifecycle.
