The Core OS group is a newly formed team building the operating-system foundation GM’s next generation of vehicle software runs on: hypervisors and virtualization, safety partitioning and health management, container runtime and workload orchestration, and the boot and secure-boot chain that let Linux, Android, and QNX share a single high-compute platform safely and efficiently. As Principal Software Engineer, you are the senior technical authority and system architect for that layer — you’ll determine which platform problems matter most, then define the architecture and drive the solutions that solve them, setting long-term direction for virtualization, partitioning, and platform services across GM’s vehicle compute. Your influence extends well past your own code: establishing the technical interfaces to the silicon, guest OS, and functional-safety organizations, driving decisions with hypervisor and silicon partners, and guiding engineers across multiple teams toward a foundation that must hold up to production performance, reliability, and safety requirements in millions of vehicles.
