Operating Systems Engineer

Responsibilities

• Design, implement, and maintain Linux kernel subsystem changes supporting device capabilities and product requirements.
• Own features across kernel and userspace by defining boundaries and building interfaces and supporting components for shipped products.
• Debug correctness, concurrency, performance, power, and reliability issues using tracing, profiling, instrumentation, and diagnostic tools.
• Develop tests and representative workloads to validate performance, power, and reliability improvements and detect regressions.
• Partner with hardware, firmware, platform, and application engineers to translate system requirements into maintainable solutions.
• Prepare reviewable kernel patches, incorporate technical feedback, contribute appropriate fixes upstream, and maintain product-specific changes as the kernel evolves.

Requirements

• Substantial hands-on experience designing, developing, and debugging one or more Linux kernel subsystems, such as memory management, storage, networking, high-speed peripherals, power management, scheduling, or virtualization.
• Proficiency in C for kernel and low-level systems development.
• Strong understanding of kernel concurrency, synchronization, memory ownership, and resource lifetimes.
• Experience delivering system capabilities across kernel and userspace, including interface design and cross-boundary problem diagnosis.
• Understanding of Linux kernel development practices, including maintainable design, appropriate abstractions, reviewable patches, compatibility awareness, and regression prevention.
• Proficiency in Rust for systems programming and experience developing Linux kernel code in Rust alongside C are preferred.
• Participation in the Linux community through patches, code review, testing, bug reports, technical discussions, or collaboration with subsystem maintainers is preferred.
