About the role

Join Apple’s Linux Kernel Engineering team to own the kernel lifecycle end to end, from CI infrastructure and automated validation to driver enablement, debugging, and production-quality releases. Collaborate with platform, infrastructure, and SRE teams to ensure kernels are stable, observable, and ready for real-world workloads at scale.

Responsibilities

  • Design, build, and operate CI and validation pipelines that compile, test, and release Linux kernels across multiple hardware platforms and Linux distributions.
  • Lead triage of kernel regressions, 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 raise the bar on kernel quality, automation, and release discipline.

Qualifications

  • Bachelor of Computer Science or equivalent skills and work experience.
  • At least 5+ years experience developing or maintaining the Linux kernel or low-level system software (e.g., kernel modules, device drivers, or core OS components).
  • Proven ability to debug kernel level issues (panics, hangs, performance regressions) 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: 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 (SRE, platform, hardware, security).
  • Proven track record of upstream contributions to the Linux kernel project or similar upstreams.
