Microsoft Network Engineer Jobs in Texas (NOW HIRING)

Position Overview

The Network Security Engineer role sits within the Information Technology Department and exists to keep the organization's WAN, LAN, voice, and cloud infrastructure running efficiently, reliably, and securely. While the role retains the full scope of traditional network engineering, this description places heightened emphasis on cybersecurity operations and Microsoft Azure security, reflecting the organization's continued shift toward hybrid and cloud-hosted infrastructure.

The successful candidate will partner with third-party providers and internal IT leadership to defend the network and cloud environment against malware, intrusion, and emerging cyber-threats; maintain firewalls, identity controls, and access policies; ensure reliable backups and disaster recovery; and act as a key contributor to the organization's overall security posture across both onpremises and Azure-hosted resources.
