  • Collaborate with the N6 staff, Information Assurance (IA) coordinators, and network administrators to ensure system functionality and security compliance.
  • Perform regular system backups and disaster recovery testing.
  • Perform shift work as required to support N63 operations and exercise and contingency requirements.
  • Proficiency in administering Windows 10 / 11 and Red Hat Linux System operating systems.
  • Understanding of core network protocols (TCP/IP), LANs/WANs, routers, switches, firewalls, and load balancers.
  • Implement and enforce system and security policies based on DoD standards, including STIGS and Risk Management Framework (RMF).
  • Provide advanced troubleshooting and system performance monitoring (i.e. CPU, memory, disk I/O).
  • Knowledge in MOC, DFC Ops, Joint Range Application C/Link 16 Protocols.
  • Administer and maintain VMware virtual environments, including vCenter Server Appliances and ESXi hosts, to ensure stable operations.
  • Manage NetApp storage arrays, providing high-performance NFS services and efficient volume management to meet data-intensive needs.
  • Deploy and maintain Gigamon V-Series virtual taps to support comprehensive traffic monitoring and visibility within the virtual environment.
  • Maintain high availability through strategic VM migrations to mitigate maintenance impacts and ensure maximum system uptime.
  • Execute software life-cycle management by staying current with the latest versions of ONTAP, ESXi, Center, and VMware Tools.
  • Enforce cybersecurity compliance by applying DoD STIGs and ensuring successful weekly vulnerability scans across all managed systems.
  • Monitor and optimize system performance, pro-actively troubleshooting and resolving complex infrastructure alerts or bottlenecks.
  • Oversee access control by managing user accounts and permissions for both the virtual environment and NetApp storage arrays.
  • Facilitate environment growth by provisioning, importing, and configuring new virtual machines based on organizational requirements.
  • Implement disaster recovery protocols, ensuring routine backups and rapid restoration capabilities to maintain business continuity.
