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
More about this 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.
This is not a firewall-administration or network break/fix role. You won't spend your days writing rule-bases, managing devices, or running a customer's network operations. You've already done that work — for years — and that is exactly what qualifies you. Those years in the trenches are what let you look at a customer's network rules, their controls, and Reach's findings and say, with authority, what matters, what doesn't, and why.
In this role you put that hard-won judgment to work: advising the field, guiding customers through their hardest problems, sharpening Reach's recommendations, and troubleshooting how Reach integrates with the network-security products already in a customer's environment. It is a high-agency individual-contributor role for a proven expert who is energized by unfamiliar problems rather than thrown by them.
You'll serve three audiences at once, and the strongest people in this seat move fluidly between them:
