Operating Systems Engineer, Linux Kernel | Consumer Devices

OpenAI • San Francisco, CA

2d • $230,000 - $385,000

About The Position

OpenAI Consumer Devices is building the next generation of products that bring powerful AI into people’s everyday lives. Guided by OpenAI’s mission to ensure AGI benefits all of humanity, our team combines world-class researchers, engineers, designers, and operators who care deeply about creating useful, intuitive, and responsible technology. You’ll have the opportunity to work alongside exceptional people on ambitious, zero-to-one challenges at the intersection of hardware, software, and AI. This is a chance to help define an entirely new category of products—and shape how people experience AI in the future.
Our team works across custom silicon, embedded systems, operating systems, and cloud services to build reliable consumer devices and the platforms behind them. We connect kernel development with the broader software stack to deliver complete product capabilities.
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.
Your ownership will extend into the userspace services, libraries, tools, and interfaces needed to deliver complete product features. You’ll shape the boundaries between kernel and userspace, make design decisions across the stack, and see your work through development, integration, and production.

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 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 validation to prevent regressions.

Nice To Haves

• Proficient in Rust for systems programming, with experience developing Linux kernel code in Rust alongside C.
• Participate in the Linux community through patches, code review, testing, bug reports, technical discussions, or collaboration with subsystem maintainers.
• Take ownership of complete solutions and follow problems across system boundaries.
• Make careful tradeoffs among functionality, security, performance, power, and maintainability, and explain your decisions with evidence.
• Work constructively through technical review and communicate clearly with teammates across disciplines.

Responsibilities

• Design, implement, and maintain Linux kernel subsystem changes that support device capabilities and product requirements.
• Choose appropriate kernel and userspace boundaries, and build the interfaces and supporting components needed to deliver reliable features in shipped products.
• Use tracing, profiling, instrumentation, and diagnostic tools to resolve correctness, concurrency, performance, power, and reliability issues in development and production.
• Develop tests and representative workloads to demonstrate repeatable performance, power, and reliability gains and detect regressions across kernel and userspace.
• Work with hardware, firmware, platform, and application engineers to turn system requirements into understandable, maintainable solutions.
• Prepare reviewable patches, incorporate feedback, and contribute fixes and improvements upstream where appropriate. Maintain product-specific changes responsibly as the kernel evolves.

Benefits

• OpenAI is an equal opportunity employer, and we do not discriminate on the basis of race, religion, color, national origin, sex, sexual orientation, age, veteran status, disability, genetic information, or other applicable legally protected characteristic.
