Senior Core Infrastructure Engineer

About the role

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.

Responsibilities

• Own software design and development for major components of OCI’s Virtual Machine dataplane.
• Dive deep into any part of the stack—Linux kernel/userspace, virtualization layers, host networking/storage integration, and distributed control interactions.
• Value simplicity and scale, and work comfortably in a collaborative, agile environment.

Qualifications

• 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.
• Strong written and verbal communication; able to explain complex technical topics clearly.

Systems Fundamentals

• Strong Linux/Unix fundamentals (processes, memory, filesystems, cgroups/namespaces, debugging).
• Working familiarity with networking (TCP/IP, routing, DNS, HTTP) and standard architectures.
• Understanding of storage systems (block/storage stacks, performance, persistence) and distributed persistence concepts.

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.

Top 3 skill sets/technologies in the ideal candidate

• Systems/software engineering in large-scale environments (Linux + distributed systems fundamentals)
• 3–5+ years owning complex components end-to-end with strong debugging/troubleshooting skills
• Virtualization expertise (QEMU/KVM, Oracle Linux, performance/reliability/security) and cloud experience
