Linux Kernel Developer

• Development of embedded software applications targeted for processor applications needed for hardware design verification and manufacturing testing.
• Linux Driver & Diagnostic development responsibilities for Ciena Packet Networking Platforms.
• Individual will participate in the development of drivers for application software as well as work on a suite of diagnostics that provides low level access/verification of system design elements as well as fully configuring and exercising the control and data paths to enable design debug and verification as well as provide a robust and high coverage manufacturing test suite.
• Solid knowledge in control plane as well as device driver development/integration for data plane elements.
• Work closely with the architecture team as well as hardware teams in creating various lowlevel drivers that enable hardware IP.
• You will be expected to closely collaborate with upstream kernel maintainers and hardware vendors in analysing root causes developing fixes and submitting patches for review.
• Engagement with the Linux open source community mailing lists any forums for collaboration and contribution.

• Knowledge of the Linux kernel and kernel subsystems.
• Knowledge of ACPI and UEFI is desirable. Understanding of power management techniques and support for managing power consumption in various devices.
• A thorough understanding of the Linux kernel architecture including process management memory management file systems and device drivers.
• Knowledge/experience with Linux kernel upstream processes and release cycle.
• Strong grasp of device drivers BSPs and other low level system engineering.
• Familiarity with development tools such as GCC (GNU Compiler Collection) Make and Git for building and version controlling the kernel.
• Demonstrated experience with kernel patching and debugging.
• Ability to write and modify device drivers for various hardware components including character block and network devices.
• Expertise in memory management including virtual memory page tables and memory allocation strategies.
• Ability to develop and manage kernel modules for adding or extending kernel functionality without recompiling the entire kernel.
• Knowledge of computer architecture and hardware components as Linux kernel development often involves platformspecific code.
• Skills in crosscompilation and porting the kernel to different hardware architectures or platforms.
• Familiarity with the networking stack in the Linux kernel including network protocols and socket programming.
• Understanding of security principles access control mechanisms and kernel security features.

• Experience : 3 Years
