Senior Linux Kernel Engineer - High-Speed Networking & WLAN

Job Summary

We are seeking a highly skilled and motivated Linux Device Driver Engineer to join our Connectivity Team. You will be responsible for designing, developing, debugging, and optimizing Linux kernel-mode drivers, wireless protocols, and connectivity stacks (WLAN 802.11a/b/g/n/ac/ax/be) for next-generation embedded products. The ideal candidate has deep knowledge of the Linux kernel, networking subsystems, and hands-on experience with PCIe/SDIO-based WiFi chipsets.

Key Responsibilities

Driver Development:

Design, implement, and maintain high-performance Linux network drivers and kernel modules for WLAN/WiFi connectivity. WLAN Protocol Stack:

Work on upper-layer protocol integration, including hostapd, wpa_supplicant, and networking stacks, to ensure robust connectivity. Debugging & Troubleshooting:

Perform root cause analysis of complex system-level issues, including kernel panics, race conditions, and memory leaks, using tools like JTAG, GDB, and ftrace. Performance Optimization:

Optimize WiFi drivers for throughput, latency, and power consumption to meet product requirements. Hardware Bring-up:

Collaborate with hardware teams to bring up new SoC platforms and WLAN peripherals. Code Review & Documentation:

Participate in design discussions and code reviews to ensure code quality and maintainability.

Required Technical Skills

Linux Kernel Expertise:

3–8 years of professional experience in Linux driver development, specifically in the networking domain. Programming Languages:

Expert-level C programming skills for embedded systems. WLAN Knowledge:

In-depth understanding of IEEE 802.11 standards, including Wi-Fi 5/6/6E/7 (802.11ac/ax/be). Interfaces:

Experience with PCIe, SDIO, or USB interfaces. Tools:

Proficient in using Git, debugging tools (Wireshark, JTAG), and building with Yocto/Buildroot.

Preferred Qualifications

Experience with specific chipset vendors (Qualcomm Atheros, Broadcom, MediaTek). Familiarity with the mac80211 framework. Knowledge of RTOS (e.g., Zephyr) is a plus.

Education

Bachelor's/Master's degree in Computer Science, Electrical Engineering, or a related field.
