## About the role

Reach Security tells organizations what their existing security tools should be doing with the products they already own — and proves it. As a Principal Support Engineer, Network, you are Reach's senior domain authority on everything network.

## What they're looking for

- 6+ years of deep, hands-on experience with enterprise network security — firewalls, segmentation, and network traffic analysis — enough to have developed genuine expertise, not passing familiarity
- Time in a senior individual-contributor role such as L3 Network Support Engineer, Network Security Engineer, Firewall Engineer, or Security Support Engineer
- Strong command of TCP/IP and network protocol internals, with the ability to reason from packet captures (Wireshark/tcpdump), flow/telemetry data, and device logs to root cause
- Depth in network segmentation and micro-segmentation, NAT, routing (BGP/OSPF), VPN (IPsec/SSL), and TLS/SSL inspection
- Experience with IDS/IPS/NDR, secure web gateways/proxies, DNS security, and modern SASE/ZTNA architectures
- Cloud network security experience — AWS security groups/NACLs, Azure NSGs, GCP firewall rules, VPCs, and connectivity/peering constructs
