Strong routing and switching fundamentals, including VLANs, trunking, spanning tree, link aggregation, QoS, MTU, and fragmentation.
Experience with enterprise or carrier-grade platforms such as Cisco IOS/NX-OS, Juniper Junos, Arista EOS, MikroTik RouterOS, or equivalent.
Practical experience with firewalls, IPsec/WireGuard/SSL VPNs, tunneling, and network access control.
Working knowledge of DNS, DHCP, NTP, TLS/PKI, and load balancing.
Strong IPv4/IPv6 addressing, subnetting, and dual-stack experience.
Strong Linux administration and command-line skills.
Proven troubleshooting skills using tcpdump, Wireshark, packet captures, and flow data.
Scripting/automation experience with Python, Bash, Go, or similar languages.
Experience with Git and configuration-as-code practices.
Ability to work independently in a remote environment, manage priorities, and communicate clearly in writing.
Legally authorized to work in the United States without sponsorship.
