Job Description

As a Senior/Staff Kernel Engineer at Weka, your primary responsibility will be collaborating with other team members on our high-performance filesystem solution and releasing our kernel driver, which is written in C on top of Linux, as part of the Weka filesystem product. The kernel-based filesystem driver provides file access and logic to Weka filesystems and the ability to connect clients to the Weka cluster. This enables the Weka system to provide applications with local filesystem semantics and performance while providing centrally-managed, shareable, and resilient storage. Our entire kernel team proudly delivers high-quality kernel drivers and you will have the opportunity to quickly become an integral contributor. As a Senior Kernel Engineer, You’ll * Design and develop core product features in a complex software system with a focus on Linux kernel and OS infrastructure layers * Provide architectural guidance and fresh ideas in our core kernel driver and related interfaces * Locate performance bottlenecks within Linux and/or its driver or other components, and suggest & implement enhancements to meet target performance goals * Most importantly, assume nothing- constantly revisit how we work and whether our productivity is perfectly tuned

Must have:

10+ years of hands-on experience in Linux kernel development and debugging
Master of low-level C development in Linux kernel
Vast experience in performance-sensitive code
Solid understanding of the VFS, page cache & file system concepts
Familiarity with kernel development methodologies and kernel structure
Experience in developing kernel modules
Top-notch experience in the Linux Kernel Driver model & development
Lock/lockless synchronization between kernel space & userspace
Broad knowledge and understanding in Linux internals, kernel subsystems (Memory Management, IO, Storage, Networking)
Kernel crash and core analysis skills
Knowledge of IO tools and performance benchmarks using standard tools
Deep understanding of threading and locking mechanisms
Highly motivated and independent engineer with a positive attitude, a creative and open mind, and fluency in English.
