Linux Kernel Engineer

What you'll do

• Design, build, and operate CI and validation pipelines for compiling and testing Linux kernels across multiple hardware platforms.
• Triage kernel regressions and investigate crashes or performance issues to drive fixes to resolution.
• Qualify new hardware at the kernel layer to ensure stability and reliability.
• Port, maintain, and upstream device drivers for various hardware components.
• Manage the end-to-end kernel lifecycle from development through production-quality releases.
• Perform deep kernel debugging using tools like perf, ftrace, bpftrace, crash, and gdb.
• Tune kernel subsystems to optimize performance and stability for real-world workloads at scale.
• Manage RHEL-based Linux environments including RPM packaging and kernel backporting processes.

What we're looking for

• Bachelor of Computer Science or equivalent skills and work experience.
• At least 5 years of experience developing or maintaining the Linux kernel or low-level system software.
• Proven ability to debug kernel issues like panics, hangs, and performance regressions using tools such as perf, ftrace, bpftrace, crash, or gdb.
• Deep understanding of kernel tuning for stability and performance across various subsystem domains.
• Hands-on experience developing CI/CD systems integrating operating system components and managing kernel releases.
• Strong programming skills in C and proficiency in at least one of Rust, Go, Python, or Bash.
• Solid understanding of OS fundamentals including memory management, filesystems, networking, scheduling, and hardware interactions.
• Experience in RHEL-based environments, including RPM packaging and the RHEL kernel backport process.
