Senior Core Infrastructure Engineer

Location: Nashville, TN, United States

Oracle Cloud Infrastructure is seeking Senior Infrastructure Engineers to design, build, and operate the high-performance virtual networking dataplane that underpins OCI gateway services. In this role, you will develop major C and C++ features for packet processing, routing, network address translation, gateway functionality, and security-policy enforcement. You will optimize CPU and memory efficiency, concurrency, latency, and throughput for production systems operating at cloud scale.

You will partner with networking, control-plane, infrastructure, security, and operations teams to build fault-tolerant distributed systems with strong tenant isolation and safe deployment practices. The role includes end-to-end feature ownership: architecture, implementation, testing, staged rollout, observability, on-call support, incident response, and continuous operational improvement. Experience with fast dataplane technologies such as DPDK, VirtIO, eBPF, XDP, SR-IOV, SmartNICs, or userspace packet-processing frameworks is especially valuable.
