o Networking (Ethernet, InfiniBand, OFED, RoCE, DPDK, and related technologies)

o Storage and Filesystems (iSCSI, Fibre Channel, NFS, ZFS, Btrfs, block layer, and filesystem layer)

o Virtual Memory Management and Performance Optimization, including large page management and container workload performance

o Security technologies such as encryption, TPM integration, signed kernels/modules, Secure Boot, and bootloader security

· Contribute to the upstream Linux kernel and drive enhancements for cloud-scale deployments.

· Collaborate closely with hardware design teams on processor bring-up and architecture enablement initiatives.

Requirements

· Strong background in operating systems development.

· Several years of hands-on Unix/Linux kernel development experience preferred.

· Proficiency in C programming and kernel-level debugging.

· Expertise in one or more Linux kernel subsystems, including networking, storage, memory management, security, or processor architecture.

· Experience with open-source development practices and upstream kernel contributions is highly desirable.

· Familiarity with Python and Bash scripting for development and automation tasks.

Preferred Experience

· High-performance networking technologies such as RoCE, advanced Ethernet networking.

· Filesystem and storage technologies including XFS, ZFS, NFS, iSCSI, Fibre Channel, and Linux block layer development.

· Virtual memory management, performance tuning, and container optimization.

· Security technologies including TPM, Secure Boot, kernel signing, and encryption frameworks.

· Live patching technologies and kernel maintenance.
