Responsibilities

• Design, implement, and validate firewall policy, network address translation, and segmentation changes across on-premises and cloud enforcement points.
•  Build and maintain remote access and site-to-site VPN services, including tunnel configuration, certificate and identity integration, and client posture checks.
•  Perform platform upgrades, failover testing, and hardware replacements within approved change windows, with tested rollback procedures.
• Troubleshoot complex connectivity and performance problems using packet capture and log analysis, and drive them to root cause with the network and application owners.
•  Automate rule analysis, recertification evidence, and configuration backup, and mentor junior engineers on policy design and change discipline.
