* ** 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** (Trust Zone, 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.
