Design and Implementation: Develop and design secure network architecture and infrastructure (firewalls, VPNs, IDS/IPS, LAN, WAN, WLAN, SD-WAN, Cloud Networks, etc.)
Maintenance and Upgrades: Perform network maintenance and system upgrades including service packs, patches, hot fixes, and security configurations for firewalls (Palo Alto, Zscaler, etc.), Cloud networks, switches, routers, and wireless.
Troubleshooting and Support: Monitor network performance, troubleshoot network problems and outages, schedule updates, and collaborate with network architects on network optimization. Provide technical support and guidance to users, possibly including training non-technical staff.
Security: Establish networking environment by designing system configuration, directing system installation, and defining, documenting, and enforcing system standards. Secure network systems by establishing and enforcing policies, and by defining and monitoring access.
Performance Monitoring: Monitor network performance and integrity, resolve issues using data from different network monitoring tools. Analyze network data to predict potential issues or bottlenecks.
Provide Tier 2/3 support for security-related incidents and escalations.
Documentation: Maintain network documentation, diagrams, and network configurations

Proficient knowledge and experience with networking technologies (i.e., WAN connectivity, access points, network switches, load-balancers, routing protocols, firewalls, VPNs, VLANs, LAN Segmentation methodologies, etc.)
Experience with firewalls (Juniper, Cisco, Palo Alto, etc.), Internet VPN’s remote implementation, troubleshooting, and problem resolution.
Good understanding of networking protocols (e.g., IPSEC, HSRP, BGP, OSPF, 802.11, 802.1x, QoS).
Experience with Wireless, Local or Wide area network technologies.
Familiarity with Cloud networking (vnet peering, vpc, etc. in Azure, AWS)
Solid knowledge of application transport and network infrastructure protocols.
Ability to create accurate network diagrams and documentation for designing and planning network communication systems.
Strong analytical skills, able to work independently, and must be able to report on network operational status by gathering and prioritizing information.
Professional Certification, such as CCNP Security, CCIE, CISSP, or CEH, is highly desirable.
