- Experience with performance optimization and advanced troubleshooting at kernel-level.
- Experience with memory managed high performance ARM Cortex-A or X86 architectures and SoCs (NXP, Freescale, Intel, AMD, Xilinx, Altera, ...).
- Experience with the Linux kernel itself or the kernel of any other operating system with strictly isolated kernel and user spaces.
- Proven success with root-cause investigation of bugs related to operating systems, hypervisors, or hardware-level drivers.
- Proficiency in the C programming language
- Proficiency with Git at a command line level
- Ability to track and work on multiple projects simultaneously while meeting schedules.
- Demonstrated experience of leading software projects while providing technical inputs to unblock supporting teams.
- Keen sense of urgency and drive for results.

• Must be able to read integrated circuit data sheets and understand register configuration procedures.
• Must understand interrupts and how to appropriately use them to our advantage
• Must understand when and how to appropriately use DMA to our advantage
- Operating System core kernel development experience
• Must have experience with scheduling and timing-related mechanisms and issues in any of the OS kernels as described above
• Must have extensive understanding with context switching, preemption, interrupts, timers, and locking mechanisms.
• Must have knowledge of Unix-style file-system data structures (inodes, ...)
• Must have knowledge of page tables and memory management.
• Must have cursory knowledge of assembly level bootstrapping in either ARM or X86 instruction sets.
Nice to have:- Experience working with open source communities to fix bugs and/or add features is a plus.
- Experience migrating drivers from one version of the Linux kernel to another is a plus.
• Scripting and automation experience with Python, bash or similar languages is a strong plus.
