Job Description

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.

This role is based in Nashville, TN

Responsibilities

Key Responsibilities:

Dataplane Scalability and Performance

Implement and enhance C and C++ components for OCI’s virtual networking dataplane, including routing, network address translation, network gateways, and security-policy enforcement.
Build packet-processing features that support scalable, multi-tenant cloud networking with guidance from senior engineers.
Profile and optimize CPU utilization, memory usage, concurrency, latency, and throughput in large-scale production environments.
Contribute to fast dataplane development using technologies such as DPDK, VirtIO, Linux networking, SR-IOV, SmartNICs, or userspace packet-processing frameworks.
Develop and maintain unit, integration, system, performance, and scale tests.
Participate in design and code reviews, applying established patterns for performance, correctness, and maintainability.

Reliability and Availability

Implement fault-tolerant networking components that handle failures, maintenance events, and software updates with minimal customer impact.
Contribute to resilient designs using health checks, retries, timeouts, graceful draining, failover, and recovery mechanisms.
Develop fault-injection, brownout, and recovery tests to validate service behavior.
Support staged deployments, automated validation, monitoring, rollback, and recovery procedures.

Observability and Operational Excellence

Build and maintain service metrics, alarms, dashboards, telemetry, canaries, and operational health checks.
Diagnose Linux, networking, performance, and production issues using logs, metrics, packet captures, traces, profilers, and debugging tools.
Create and improve runbooks, diagnostic tools, and automation for common operational issues.
Participate in the team’s on-call rotation, incident response, root-cause analysis, and corrective-action follow-through.

Security and Multi-Tenant Isolation

Apply established security and tenant-isolation practices to dataplane and gateway features.
Help identify and remediate security, reliability, and operational risks.
Maintain technical documentation and follow applicable security, compliance, and change-management processes.

Automation and Change Management

Maintain automation and infrastructure-as-code used to build, test, deploy, and operate the service.
Implement automated checks and safeguards for configuration changes, software releases, and rollback procedures.
Own assigned features through implementation, testing, deployment, production validation, and support.

Core Responsibilities:

Planning and Execution

Plan and deliver assigned work with limited supervision, identifying dependencies and risks early.
Manage priorities and adjust execution as requirements, timelines, or production needs change.
Communicate progress, blockers, and technical decisions clearly.

Collaboration and Partnership

Work closely with networking, control-plane, infrastructure, security, and operations teams.
Participate in design reviews, code reviews, incident reviews, and knowledge-sharing activities.
Document technical decisions and contribute to team standards and best practices.

Problem Solving

Independently troubleshoot standard and moderately complex issues using established engineering practices.
Analyze data from logs, metrics, traces, packet captures, and tests to identify root causes.
Escalate complex cross-service issues appropriately while contributing to their resolution.

Continuous Learning and Improvement

Build expertise in C/C++, systems programming, cloud networking, Linux, and high-performance dataplane technologies.
Seek feedback and apply it to improve technical and operational skills.
Identify practical opportunities to improve testing, tooling, deployment, observability, and team workflows.

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.
