- Support network segmentation initiatives using firewall policies, NAC enforcement, VLANs, security zones, and identity-based access controls.
- Manage and enhance network security technologies, including solutions from Palo Alto Networks and Fortinet.
- Troubleshoot complex network and security issues involving firewalls, routing, switching, DNS, DHCP, certificates, authentication, cloud networking, endpoint posture, and VPN connectivity.
- Develop automation and integrations using APIs and scripting to improve reporting, efficiency, and operational processes.
- Create and maintain technical documentation, including security standards, diagrams, implementation plans, runbooks, troubleshooting guides, and rollback procedures.
- Review firewall and NAC policies to ensure they remain secure, effective, and aligned with business requirements.
- Partner with Network Engineering, Security Operations, Infrastructure, Cloud, and Endpoint teams to deliver secure, reliable access to business applications.
- Participate in incident response, technical investigations, root cause analysis, and remediation efforts involving network security controls.
- Mentor fellow engineers by sharing technical expertise and supporting their professional development.
- Contribute to additional network and infrastructure security initiatives as business needs evolve.
