Required Senior Software Engineer, Kernel
About The Position
As a Senior Kernel Engineer, 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 filesystem product.
The kernel-based filesystem driver provides file access and logic to our filesystems and the ability to connect clients to the cluster. This enables the 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, youll:
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.
Requirements: 6+ years of hands-on experience in Linux kernel development and debugging
Master of low-level C development in Linux kernel, with vast experience in performance-sensitive code and a solid understanding of the VFS, page cache & file system concepts
Familiarity with kernel development methodologies and kernel structure, as well as experience in developing kernel modules
Top-notch experience in the Linux Kernel Driver model & development
Lock/lockless synchronization between kernel space & user space
Broad knowledge and understanding in Linux internals, kernel subsystems (Memory Management, IO, Storage, Networking), and kernel crash and core analysis skills
Knowledge of IO tools and performance benchmarks using standard tools
A deep understanding of threading and locking mechanisms
A highly motivated and independent engineer with a positive attitude, a creative and open mind, and fluency in English.
It's nice if you have:
A background in working with the Linux kernel community
Experience contributing/up-streaming/maintaining kernel code
Knowledge of storage subsystems, storage stack, and protocols (NVMe, NFS, Samba, filesystems), along with development experience with enterprise-grade storage solutions
Experience hacking complex open-source projects.
This position is open to all candidates.
