Solid understanding of networking fundamentals including TCP/IP, VLAN, DHCP, DNS, NAT, and firewalling
Familiarity with UCI configuration, LuCI web interface, and system logging
Experience with cross-compilation toolchains and hardware debugging using JTAG or serial consoles
Strong exposure to WiFi standards (802.11 a/b/g/n/ac/ax) and networking chipsets such as Atheros, Broadcom, and MediaTek
Nice to Have
Experience with IPSec, OpenVPN, WireGuard, and WPA3
Exposure to cloud or device management protocols such as MQTT, TR-069, or IoT platforms
Understanding of hardware design fundamentals including PCB layout and SoC integration
Contributions to OpenWRT or other open-source networking projects
What Works Well in This Role
Strong problem-solving ability with close attention to detail
Comfort working independently in fast-paced environments
Clear communication and strong documentation skills
Why This Role
Hands-on ownership of next-generation internet infrastructure firmware
