As a Linux Kernel Engineer at Apple, you will be integral to the reliability and performance of Apple's platforms. You will manage the entire kernel lifecycle, from CI infrastructure to production-quality releases. This role involves close collaboration with various teams to ensure stable and observable kernels ready for real-world workloads. If you have a passion for deep kernel debugging and building robust CI systems, this position offers a chance to make a significant impact.

• 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 level issues using tools such as perf, ftrace, bpftrace, crash, gdb, or similar.
• Deep understanding of kernel tuning for stability and performance across many subsystem domains.
• Hands-on experience developing CI/CD systems integrating operating system components and managing kernel releases.
• Strong programming skills in C, plus proficiency in at least one of Rust, Go, Python, or Bash.
• Solid understanding of operating system fundamentals including processes, memory management, filesystems, networking, scheduling, interrupts, and hardware/driver interactions.
• Experience working in a RHEL based Linux environment, including RPM packaging and the RHEL kernel back port and release process.
• Strong collaboration and communication skills; comfortable working with cross-functional teams.
• Proven track record of upstream contributions to the Linux kernel project or similar upstreams.

• Own the kernel lifecycle end to end, from CI infrastructure and automated validation to driver enablement and debugging.
• Design, build, and operate CI and validation pipelines that compile, test, and release Linux kernels across multiple hardware platforms.
• Lead triage of kernel regressions and investigate crashes and performance issues.
• Drive fixes to resolution and qualify new hardware at the kernel layer.
• Collaborate with engineers across Apple to port, maintain, and upstream device drivers.
• Shepherd kernel changes into production and continuously improve kernel quality, automation, and release discipline.
