  • Respond to security incidents in coordination with the security operations team, including root cause analysis and remediation.
  • Support core network infrastructure, including routers, switches, and wireless controllers.
  • Participate in change management processes and assist with root cause analysis for network or security-related problems.
  • Ensure SLAs are met and contribute to regular performance and incident reporting using ITSM/ITOM tools.
  • Contribute to capacity planning and system optimization efforts for both firewall and network components.
  • Maintain clear and updated documentation for configurations, troubleshooting procedures, and network policies.

Requirements

Must-Have:

  • Diploma or degree in IT, Computer Science, or related field.
  • 3 to 5 years of hands-on experience with firewall administration and enterprise network support.
  • Strong working knowledge of firewall platforms such as Palo Alto, Fortinet, or Cisco ASA/Firepower.
  • Solid understanding of key network protocols (TCP/IP, VLANs, VPNs, BGP, OSPF).
  • Familiarity with intrusion detection/prevention systems and network security monitoring tools.
  • Experience with ITSM/ITOM platforms for ticketing, incident, and change management.
  • Comfortable working across multiple sites and supporting both onsite and remote environments.
  • Strong problem-solving, troubleshooting, and analytical skills.

Preferred:

  • Certifications like CCNP Security, Fortinet NSE, or Palo Alto PCNSE.
  • Background in healthcare IT or large enterprise environments.
  • Knowledge of vulnerability scanning and remediation processes.

Work Environment:
