On the operations side, you'll plan and execute network changes following change-management and security governance processes, continuously monitor and optimize network performance and security posture, and provide advanced troubleshooting for complex network issues. You'll configure and maintain secure connectivity services (VPN/ZTNA, HTTPS, SFTP), create operational documentation, mentor operational teams, and engage vendors for escalated support and technology evaluations. You'll participate in on-call rotations and lead network upgrades within maintenance windows.
Required: 6+ years supporting complex production network systems; expertise in routing, switching, and security architectures; proficiency in at least one Network OS (NX-OS, JunOS, Arista EOS) and one Network Security OS (PAN-OS, FortiOS); hands-on experience with network automation and infrastructure-as-code (Terraform, Ansible, Python); strong firewall, segmentation, and VPN knowledge; excellent troubleshooting and communication skills; and a bachelor's degree in a technical discipline or equivalent professional certification (CCNP, JNCIS, VCP-NV). Experience building scalable hybrid infrastructure connectivity is essential.
Preferred: Juniper and Palo Alto expertise with Panorama; WLAN and 802.1x/RADIUS knowledge; NAC and ZTNA/SASE solutions experience (Prisma, Zscaler, Cato); virtualization or OS administration background; demonstrated project management and leadership; and a collaborative, solution-driven mindset in fast-paced environments.
