Operating Systems Engineer, Linux Kernel | Consumer Devices

Job summary

Responsibilities

As an Operating Systems Engineer focused on the Linux kernel, you will design, develop, and maintain the kernel capabilities that underpin OpenAI’s consumer devices. You’ll bring deep expertise in one or more Linux kernel subsystems and carry solutions through the higher-level software stack.

• Build kernel capabilities: Design, implement, and maintain Linux kernel subsystem changes that support device capabilities and product requirements.
• Own features across the stack: Choose appropriate kernel and userspace boundaries, and build the interfaces and supporting components needed to deliver reliable features in…
• Debug complex system behavior: Use tracing, profiling, instrumentation, and diagnostic tools to resolve correctness, concurrency, performance, power, and reliability issues in…
• Measure and validate improvements: Develop tests and representative workloads to demonstrate repeatable performance, power, and reliability gains and detect regressions across…
• Partner across disciplines: Work with hardware, firmware, platform, and application engineers to turn system requirements into understandable, maintainable solutions.

What they're looking for

• Substantial hands-on experience designing, developing, and debugging one or more Linux kernel subsystems, such as memory management, storage, networking, high-speed peripherals…
• Proficiency in C for kernel and low-level systems development.
• Strong understanding of kernel concurrency, synchronization, memory ownership, and resource lifetimes.
• Experience delivering systems capabilities across kernel and userspace, including designing interfaces and diagnosing problems that cross that boundary.
• Understanding of Linux kernel development principles and practices: maintainable designs, appropriate abstractions, reviewable patches, compatibility awareness, and careful…
