Summary

We are looking for an experienced Linux Kernel Developer with strong expertise in device driver development, kernel internals, and high-speed interface protocols. The candidate will work on low-level driver development, kernel optimization, and hardware-software integration for high-performance embedded systems.

Roles & Responsibilities

Design, develop, and maintain

Linux kernel device drivers

for various subsystems (character/block/network/storage/multimedia/PCIe/I2C/SPI/USB/etc.). Work extensively with

high-speed interfaces

such as

PCIe, USB 3.x, Ethernet (1G/10G/25G), MIPI, SerDes

, etc. Implement and debug kernel modules, ensuring seamless integration with user-space applications. Work with Linux kernel subsystems:

interrupt handling, memory management, power management, DMA, scheduler

. Participate in

board bring-up

, including bootloader (U-Boot) setup, kernel configuration, and Device Tree updates. Collaborate with hardware and embedded teams to analyze schematics, SoC datasheets, and driver requirements. Optimize driver performance, reduce latency, and improve throughput for high-speed data paths. Perform kernel debugging using

KGDB, crash tools, ftrace, printk, perf, LTTng

, etc. Handle kernel patching, customization, and version upgrades. Create technical documentation and participate in design reviews.

Mandatory Skills

3 to 8 years

of experience in

Linux Kernel & Device Driver development

. Strong expertise in

C programming

and embedded systems.

Hands-on experience with high-speed protocols

(mandatory):

PCIe

USB 3.x

Ethernet (1G/10G/25G+)

SerDes / MIPI / CSI / DSI (any applicable)

Experience with: Platform / Character drivers DMA engine and interrupt handling Synchronization (spinlocks, mutexes, atomic operations) Device Tree, cross-compilation, kernel configuration Strong understanding of kernel subsystems: IRQs, workqueues, timers, memory management. Experience with embedded Linux, BSP, Yocto/Buildroot.

Preferred Skills

Experience with ARM/RISC-V/x86 architecture. Experience with

high-speed signal debugging

(scope, logic analyzer). Familiarity with

PREEMPT_RT

or real-time systems. Contributions to Linux kernel or open-source projects. Knowledge of U-Boot, firmware development.
