We are seeking a highly experienced Principal Embedded Firmware Engineer to architect, drive, and optimize the firmware lifecycle for our next-generation networking devices. In this senior role, you will tackle our most complex technical challenges across Wi-Fi routers, gateways, and access points. From writing robust C/C++ code to leading deep packet analysis and system triage, you will set the technical standard for the team. If you are a seasoned expert in embedded Linux environments and wireless networking protocols, we want you to help shape our core technology.

Responsibilities include, but are not limited to the following:

• Firmware Architecture & Development: Architect, develop, and optimize high-performance firmware applications using C and modern C++ (C++11/14) in embedded Linux environments.
• Advanced Network & Packet Analysis: Lead deep packet inspection and network traffic analysis using Wireshark, tcpdump, and wireless sniffers to resolve the most difficult connectivity dropouts, protocol anomalies, and latency issues.
• System Triage & Complex Debugging: Drive the diagnosis of critical system issues via shell terminals (SSH, serial). Extract and analyze log bundles, investigate complex kernel/application-layer crashes, and isolate root causes that evade standard debugging.
• Wireless & Gateway Validation: Oversee the rigorous validation of end-to-end Wi-Fi performance across all bands (2.4GHz / 5GHz / 6GHz). Ensure bulletproof stability for band/AP steering, mesh networking, and core router features (DHCP, NAT, Firewall, QoS, and Parental Controls).
• Defect Resolution & Reporting: Set the standard for engineering documentation. Produce highly detailed bug reports with reproducible steps, system state observations, log files, and packet captures (.pcap) to accelerate cross-functional resolution.
• Test Automation & Tooling: Design and maintain robust Python and shell scripting frameworks to automate complex test cases, streamline log collection, and execute large-scale soak testing routines.

You'll need to have:

• Bachelor’s degree or four or more years of work experience.
• Six or more years of relevant experience required, demonstrated through one or a combination of work and/or military experience, or specialized training.
• Willingness to travel up to 25% of the time.

Even better if you have one or more of the following:

• Experience: Hands-on firmware or software development experience in networking and embedded systems, with deep, specialized expertise in Wi-Fi routers, gateways, or access points.
• Programming: Master-level expertise writing production-quality code in C and C++ (C++11/14).
• Linux Proficiency: Deep command of Linux/Unix terminal environments, including advanced core commands, standard debugging tools, shell scripting, and system/memory process monitoring.
• Network Traffic Analysis: Extensive, authoritative experience capturing and analyzing core network protocols (TCP/IP, UDP, DNS, DHCP, ARP, ICMP) using industry-standard tools.
• Wi-Fi Domain Expertise: Comprehensive understanding of IEEE 802.11 standards (a/b/g/n/ac/ax/be), wireless security protocols (WPA2/WPA3), WPS, and the physical/MAC layer mechanisms behind common RF performance bottlenecks.
• Experience architecting, configuring, and deploying applications using Docker and containerized embedded development environments.
• Strong working knowledge of open-source router operating systems (OpenWrt, prplOS, RDK-B) or proprietary vendor-specific router SDKs (e.g., Qualcomm, Broadcom, MediaTek).
• Hands-on experience designing hardware test environments, including RF sniffers, chambers, and network traffic generators (e.g., Spirent, Ixia, or iPerf).
