Responsibilities

• 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.

Requirements

• 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.
