*Position Overview*
We are seeking an experienced Network Engineer to join our enterprise infrastructure team in San Diego, California. This position is focused on the day-to-day operation, support, maintenance, and troubleshooting of a large-scale corporate network environment.
This is an operational network engineering position focused on supporting and troubleshooting an existing enterprise network environment. This is not a network architecture or design-focused role.
This is a highly operational role responsible for ensuring the reliability, performance, and security of the organization's network infrastructure. The ideal candidate will have strong hands-on experience supporting enterprise networking technologies and a passion for diagnosing and resolving complex technical issues. This position is best suited for a network engineer who enjoys troubleshooting production environments rather than designing greenfield network architectures.
The successful candidate will work closely with IT operations, security, infrastructure, and business stakeholders to maintain a stable and secure network environment while responding to incidents, service requests, and operational challenges.
*Key Responsibilities:*
* Provide operational support for enterprise network infrastructure, including routing, switching, wireless networking, firewalls, and WAN connectivity.

* Support Cisco Catalyst 9400 switching infrastructure, including VLANs, trunking, Spanning Tree Protocol, port configurations, and network performance issues.
* Support Aruba wireless networking environments, including access points, controllers, authentication services, client connectivity, and wireless performance optimization.
* Support SD-WAN infrastructure and troubleshoot branch connectivity, application performance, failover events, latency, and packet loss issues.
* Perform root cause analysis for network outages and recurring operational issues.
* Monitor network health, performance, availability, and capacity across the enterprise environment.
* Collaborate with security teams to investigate connectivity and security-related events.
* Coordinate with telecommunications providers and vendors to resolve circuit and service issues.
* Maintain accurate network documentation, diagrams, configurations, and operational procedures.
* Participate in planned maintenance activities, upgrades, patching, and change management processes.
* Support incident response efforts during critical outages and high-priority production events.
*Typical Issues You May Resolve*
* Users unable to access critical business applications.
* Site-to-site VPN connectivity failures.
* Palo Alto firewall policy or NAT-related connectivity issues.
* Wireless connectivity and performance problems.
* Branch office connectivity outages.
* SD-WAN failover and routing issues.
* High latency, packet loss, or network performance degradation.
* Cisco switching and VLAN-related connectivity problems.
* DHCP and DNS-related network service issues.
* Network outages impacting business operations.
*Required Qualifications*
* 8+ years of hands-on enterprise network engineering experience.
* Strong troubleshooting experience in complex production network environments.
* Experience supporting Palo Alto Networks firewalls.
* Experience supporting Cisco enterprise switching environments, preferably Cisco Catalyst 9400 series.
* Experience supporting Aruba wireless networking solutions.
* Experience supporting WAN and SD-WAN technologies.
* Strong understanding of TCP/IP, routing, switching, VLANs, VPNs, DNS, DHCP, and network security concepts.
* Experience working within IT Service Management environments utilizing ServiceNow or similar ticketing systems.
* Ability to perform root cause analysis and effectively resolve complex technical issues.
* Strong verbal and written communication skills.
*Preferred Qualifications*
* Palo Alto Networks Certified Network Security Engineer (PCNSE)

The ideal candidate is a strong problem solver who thrives in production environments, enjoys troubleshooting complex issues, and takes pride in keeping critical business systems running smoothly.
