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.\nYou 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.\nThis role is based in Nashville, TN\n Key Responsibilities:\nDataplane Scalability and Performance\nImplement and enhance C and C++ components for OCI’s virtual networking dataplane, including routing, network address translation, network gateways, and security-policy enforcement.\nBuild packet-processing features that support scalable, multi-tenant cloud networking with guidance from senior engineers.\nProfile and optimize CPU utilization, memory usage, concurrency, latency, and throughput in large-scale production environments.\nContribute to fast dataplane development using technologies such as DPDK, VirtIO, Linux networking, SR-IOV, SmartNICs, or userspace packet-processing frameworks.\nDevelop and maintain unit, integration, system, performance, and scale tests.\nParticipate in design and code reviews, applying established patterns for performance, correctness, and maintainability.\n\nReliability and Availability\nImplement fault-tolerant networking components that handle failures, maintenance events, and software updates with minimal customer impact.\nContribute to resilient designs using health checks, retries, timeouts, graceful draining, failover, and recovery mechanisms.\nDevelop fault-injection, brownout, and recovery tests to validate service behavior.\nSupport staged deployments, automated validation, monitoring, rollback, and recovery procedures.\n\nObservability and Operational Excellence\nBuild and maintain service metrics, alarms, dashboards, telemetry, canaries, and operational health checks.\nDiagnose Linux, networking, performance, and production issues using logs, metrics, packet captures, traces, profilers, and debugging tools.\nCreate and improve runbooks, diagnostic tools, and automation for common operational issues.\nParticipate in the team’s on-call rotation, incident response, root-cause analysis, and corrective-action follow-through.\n\nSecurity and Multi-Tenant Isolation\nApply established security and tenant-isolation practices to dataplane and gateway features.\nHelp identify and remediate security, reliability, and operational risks.\nMaintain technical documentation and follow applicable security, compliance, and change-management processes.\n\nAutomation and Change Management\nMaintain automation and infrastructure-as-code used to build, test, deploy, and operate the service.\nImplement automated checks and safeguards for configuration changes, software releases, and rollback procedures.\nOwn assigned features through implementation, testing, deployment, production validation, and support.\nCore Responsibilities: \nPlanning and Execution\nPlan and deliver assigned work with limited supervision, identifying dependencies and risks early.\nManage priorities and adjust execution as requirements, timelines, or production needs change.\nCommunicate progress, blockers, and technical decisions clearly.\nCollaboration and Partnership\nWork closely with networking, control-plane, infrastructure, security, and operations teams.\nParticipate in design reviews, code reviews, incident reviews, and knowledge-sharing activities.\nDocument technical decisions and contribute to team standards and best practices.\nProblem Solving\nIndependently troubleshoot standard and moderately complex issues using established engineering practices.\nAnalyze data from logs, metrics, traces, packet captures, and tests to identify root causes.\nEscalate complex cross-service issues appropriately while contributing to their resolution.\nContinuous Learning and Improvement\nBuild expertise in C/C++, systems programming, cloud networking, Linux, and high-performance dataplane technologies.\nSeek feedback and apply it to improve technical and operational skills.\nIdentify practical opportunities to improve testing, tooling, deployment, observability, and team workflows.\n Disclaimer:Certain U.S. based or U.S. customer or client-facing roles may be required to comply with applicable requirements, such as immunization/occupational health mandates, and/or drug testing requirements.\nRange and benefit information provided in this posting are specific to the stated locations only\nUS: Hiring Range in USD from: $79,200 to $209,500 per annum. May be eligible for bonus and equity.\nOracle maintains broad salary ranges for its roles in order to account for variations in knowledge, skills, experience, market conditions and locations, as well as reflect Oracle's differing products, industries and lines of business.\nCandidates are typically placed into the range based on the preceding factors as well as internal peer equity.\nOracle US offers a comprehensive benefits package which includes the following:\n1.
