  • Cisco Administration: Deploy, configure, and manage Cisco hardware including Nexus and Catalyst switches, routers, Firepower/ASA firewalls, and wireless systems.
  • Proactive Monitoring: Use network monitoring tools to track performance, identify bottlenecks, apply security patches, and perform routine updates.
  • Change Execution: Plan and implement scheduled maintenance, firmware upgrades, and network changes to minimize operational impact.
  • Documentation & On-Call: Maintain up-to-date network topologies, standard operating procedures, and inventory while participating in an on-call rotation.

Your Profile

  • Experience: 3-5+ years of hands-on network operations and engineering experience in enterprise, industrial, or critical infrastructure environments.
  • Cisco Expertise: Strong working knowledge of Cisco IOS, IOS-XE, and NX-OS platforms.
  • Networking Protocols: Solid understanding of BGP, OSPF, STP, VLANs, IPsec VPNs, NAT, and network segmentation.
  • Certifications: CCNA required; CCNP Enterprise or Security highly regarded.
  • Technical Tools: Familiarity with network monitoring solutions (e.g., SolarWinds, Cisco DNA Center), Wireshark, and enterprise ticketing platforms.
  • Operational Skills: Strong problem-solving abilities, disciplined change-management habits, and clear communication skills.
