NIO’s product portfolio consists of the ES8, a six-seater smart electric flagship SUV, the ES7 (or the EL7), a mid-large five-seater smart electric SUV, the ES6, a five-seater all-round smart electric SUV, the EC7, a five-seater smart electric flagship coupe SUV, the EC6, a five-seater smart electric coupe SUV, the ET7, a smart electric flagship sedan, and the ET5, a mid-size smart electric sedan.

About the PositionThis role is ideal for an experienced kernel or hypervisor engineer who wants to work hands-on with the foundations of NIO’s in-vehicle compute platform. You will join the core system software team behind SkyOS-H, NIO’s in-house hypervisor, and other SkyOS variants — contributing from architecture design to production deployment in next-generation intelligent vehicles.

• Hypervisor & Kernel Performance at Scale

You’ll work on low-level system software designed for real-time, high-efficiency, and safety-critical automotive environments. This includes optimizing latency and throughput, refining vIRQ handling, improving cache and memory subsystem efficiency (SMMU, coherency, and paging), and leveraging Arm V8 virtualization extensions (VHE). You will contribute to hypervisor scheduling, partition isolation, and secure domain management to achieve automotive-grade determinism and performance on modern SoCs.

• End-to-End Impact & Intelligent Vehicle Systems

From early architecture exploration to kernel integration, driver development, validation, and production rollout — your work will directly power live vehicle systems. You’ll enable mission-critical domains such as AD/ADAS compute, sensor fusion, and secure boot/trusted execution (TrustZone, OP-TEE).In collaboration with AI and cloud teams, you’ll also support emerging LLM-based intelligent copilots and in-vehicle assistants, where hypervisor-level performance and scheduling directly enhance on-vehicle AI responsiveness. This role offers a rare opportunity to build real products that blend operating systems, virtualization, and intelligence at the edge — all within a fast-moving automotive environment. Roles and Responsibilities:

• Develop and execute a microkernel-based operating system and hypervisor tailored for diverse on-vehicle applications in autonomous driving vehicles.
• Analyze and enhance operating system functionalities for real-time performance, high efficiency, security, and functional safety.
• Collaborate with the team to discuss and refine designs and implementations.
• Lead through demonstration, serving as both a mentor and a mentee to foster team growth and knowledge sharing.
