The ideal candidate will have 5 to 8 years of experience designing and developing embedded software firmware for Wi-Fi 6 and Wi-Fi 7 chipsets. Your work will focus on firmware modules such as Upper MAC, Lower MAC, PHY integration, data and control paths, and performance enhancements operating within real-time operating system (RTOS) environments.

Key Responsibilities

• Develop, implement, and maintain robust Wi-Fi firmware modules focused on Data Path, Control Path, Upper MAC, Lower MAC, and PHY layers.
• Enhance protocols and features specific to Wi-Fi 6 and Wi-Fi 7 standards.
• Troubleshoot and resolve critical firmware issues impacting system performance, stability, and throughput.
• Collaborate closely with hardware, RF, and systems engineering teams to ensure seamless firmware functionality across all platform layers.
• Optimize firmware for real-time embedded systems adhering to strict timing and system key performance indicators.
• Participate actively in code reviews, firmware bring-up, and deployment to production hardware platforms.
• Ensure compliance with regulatory standards such as FCC and ETSI and enforce feature conformance including DFS, CCA, and Spectral Scan functionalities.

Required Skills and Experience

• At least 5 years of embedded software experience focused on Wi-Fi or cellular firmware development.
• Comprehensive understanding of IEEE 802.11 protocols, with emphasis on Wi-Fi 6 and Wi-Fi 7 MAC and PHY layers, or equivalent cellular technologies (LTE/5G).
• Strong expertise in real-time operating systems (RTOS) and debugging firmware bottlenecks and stability problems.
• Hands-on experience with major Wi-Fi chipsets from Qualcomm, Broadcom, MediaTek, Intel, or similar vendors.
• Proficiency with debugging tools such as Wireshark, GDB, iperf, and protocol sniffers.

Preferred (Advantageous) Qualifications

• Experience with Qualcomm Wi-Fi or cellular chipsets.
• Basic familiarity with host-side driver development including cfg80211, nl80211, and netlink interfaces.
• Knowledge of Linux wireless userspace applications like hostapd and wpa_supplicant.
• Exposure to embedded Wi-Fi platform tools such as OpenWRT, Yocto, and QSDK.
• Understanding of multiple duplexing technologies: TDD/TDMA and FDD/FDMA.
• Basic knowledge of bootloaders, BSP bring-up, and U-Boot configuration.
• Experience with RF-related firmware features including DFS, Spectral Scan, transmit power control, and channel calibration.
• Hands-on involvement with RF equipment such as spectrum analyzers and calibration methodologies.
