Test and reproduce customer issues in internal and cloud-based lab environments using network simulation and validation tools.
Maintain accurate, timely case records in our case management system to ensure AppGate delivers top-tier support.
Serve as the escalation point for L2 support engineers, mentoring them and sharing knowledge to raise overall team capability.

Hands-on experience with network security platforms, including next-generation firewalls and intrusion detection and prevention systems (IDS/IPS) from multiple vendors such as Cisco, Check Point, Palo Alto Networks, CrowdStrike and Zscaler.

Functional and personal skills:

Excellent verbal and written communication skills with the ability to bridge technical and business stakeholders
At least five years of enterprise technical support or network engineering experience, including two or more years in an escalation (L3) role
A cross-functional team player who can also work independently and adapt quickly to changing situations
