Job DescriptionDepartment Description:Oracle Cloud Infrastructure (OCI) Compute delivers secure, high-performance Virtual Machines for customers worldwide. The Virtual Machine Dataplane team builds and operates the core virtualization and host-side systems that power OCI VMs at scale. We work deeply in Oracle Linux and the virtualization stack (QEMU/KVM), focusing on performance, reliability, security isolation, and operational excellence in a multi-tenant cloud.
Position Overview:We're looking for hands-on engineers with deep systems expertise and a passion for building reliable virtualization platforms. As an ideal candidate, you will have designed and implemented large-scale services and/or low-level systems in a distributed cloud environment. You will combine strong Linux fundamentals with software engineering skills to build, troubleshoot, and evolve critical dataplane components. You will champion best practices in engineering, testing, security, and operations to deliver scalable, highly available VM infrastructure.
ResponsibilitiesKey Responsibilities
As a Senior Core Infrastructure Engineer, you will own software design and development for major components of OCI's Virtual Machine dataplane. You should be a rock-solid engineer who can dive deep into any part of the stack-Linux kernel/userspace, virtualization layers, host networking/storage integration, and distributed control interactions. You value simplicity and scale, and work comfortably in a collaborative, agile environment.
Candidate ProfileExperience- BS/MS in Computer Science or related technical field or equivalent practical experience.
- 3-5+ years delivering and operating large-scale, highly available systems (cloud, virtualization platforms, or systems software).
- Strong knowledge of Java or C/C++ and/or Go , plus scripting (Python/Bash/Perl).
- Strong knowledge of operating systems, data structures/algorithms, concurrency, and distributed systems fundamentals.
- Results-driven; thrives in an agile, collaborative environment, including ambiguity and fast iteration.

Technologies (desired)- Virtualization experience (strong plus): QEMU/KVM, libvirt, virtio, VM lifecycle, snapshots, live migration concepts, CPU/memory performance tuning.
- Familiarity with host/kernel observability and debugging tools (perf, ftrace, eBPF, gdb, strace).
- Experience with CI/CD, build automation, testing frameworks; focus on regression prevention and reliability.
- Strong troubleshooting and performance tuning skills across Linux + virtualization stacks.
- Experience with multi-tenant isolation and security (hardening, attack surface reduction) is a plus.
- Experience integrating with hardware/firmware features (NUMA, SR-IOV, CPU features, accelerators) is a plus.
