Principal Core Infrastructure Engineer

The Virtual Machine Data Plane team builds the hypervisor technology that powers Oracle Cloud Infrastructure’s virtual machines. We enable secure, high-performance, multi-tenant compute: allowing a single physical host to safely and efficiently run many independent customer VMs. You’ll work at the intersection of low-level systems software, modern server hardware, virtualization, and cloud-scale reliability. Our work directly shapes how customers experience OCI Compute—from launching an instance to keeping it secure and available through infrastructure maintenance. What you’ll work on:

Enable new compute platforms across Intel, AMD, and Arm architectures. Develop virtualization and hypervisor capabilities that deliver strong performance, isolation, and reliability for multi-tenant workloads. Build live-migration technology that transparently moves a running VM between physical hosts, allowing critical infrastructure maintenance with minimal disruption—typically only a pause measured in tens of milliseconds. Strengthen the security foundation of cloud compute through capabilities such as Shielded Instances and Confidential Computing Collaborate with hardware vendors and partner engineering teams to bring new platforms and capabilities into OCI at scale. Solve difficult systems problems involving CPU virtualization, memory management, device emulation, networking, storage, observability, and fault recovery.

We’re looking for engineers who enjoy working close to the hardware and are excited by problems where correctness, performance, security, and availability all matter. Experience with systems programming, operating systems, virtualization, distributed systems, cloud infrastructure, or performance engineering is especially relevant. This is a team where you can help define the infrastructure layer beneath millions of workloads—and make cloud compute more capable, resilient, and secure.
