Principal Software Engineer, Core Infrastructure - OCI Networking

Oracle Corporation; Nashville (TN); On-site; USD 120,000 - 170,000; Full time

Job summary

Oracle Corporation's OCI Virtual Networking Control Plane team builds and manages scalable, multi-tenant cloud networking resources. You will own design and implementation of distributed systems that support high throughput, elasticity, and fault tolerance for virtual networking APIs and workflows.

The role emphasizes system reliability, security, and operational readiness, with responsibilities spanning design, testing, incident response, and automation of cloud networking infrastructure.

Responsibilities

• Lead scalable distributed systems design and implementation for horizontal and vertical scaling.
• Design systems to scale with elasticity and ensure performance testing.
• Build fault-tolerant components with redundancy, replication, and automatic failover.
• Define KPIs and telemetry to monitor health and reliability of services.
• Participate in incident response and drive root-cause analysis and remediation.
• Implement security controls and compliance measures for multi-tenant environments.

Job description

The Oracle Cloud Infrastructure (OCI) team builds and manages a suite of massive scale, integrated cloud services in a broadly distributed, multi-tenant cloud environment. OCI is committed to providing the best in cloud products that meet the needs of our customers who are tackling some of the world’s biggest challenges.

This is an opportunity to become a part of Virtual Networking Control Plane organization, a core OCI team that own and manage networking resources in virtual and functional layers. We serve internal customers in OCI and external customers that use virtual networking APIs and workflows.

Virtual Networking team delivers Network-as-a-Service that handle planning, provisioning, life cycle management and security of our customers' network infrastructure.We are shaping the management of network infrastructure by providing the flexibility and simplicity of a virtual network but with the manageability and control of a software defined network (SDN).

Internal Responsibilities

System Design & Architecture

System Scalability:

• Lead the development and implementation, and begin to architect, components of scalable distributed systems that support horizontal and vertical scaling to meet system demands, including leveraging distributed state management tools.
• Optimize code and/or systems for large-scale data processing and high-throughput requirements to support hyper-scale systems.
• Define scalability requirements for owned components and ensure design and implementation requirements are met.
• Design systems to scale with elasticity (e.g., effectively scaling both up and down).
• Leverage data plane platforms to effectively handle large-scale data retrieval, storage, and processing.
• Design performance and load testing.

System Reliability Design:

• Build and design fault-tolerant components and systems capable of withstanding in-service updates by implementing redundancy, replication, and automatic failover mechanisms.
• Design systems to effectively handle service disruptions (e.g., network partitions) by prioritizing consistency, availability, or partition tolerance.
• Implement and optimize approaches to handle network unreliability, including load-shedding, throttling, and rate-limiting.
• Design components and systems that are durable and adhere to service level objectives (SLOs), setting expectations for availability and durability of other computing services within the department.

System Reliability Performance:

• Define key performance indicators (KPIs) and telemetry to identify gaps or issues in running systems.
• Build and customize moderately complex dashboards, telemetry systems, and alerting mechanisms to proactively monitor components and system health

Correctness / Availability:

• Design and implement functional and correctness requirements for feature sets and/or systems in new or existing systems.
• Design complex test scenarios (e.g., fault-injection, brown-out) to evaluate system correctness.
• Implement data replication and synchronization techniques to maintain data integrity and availability.

Operational Troubleshooting & Incident Management:

• Take a proactive role in diagnosing, debugging, and resolving issues in active components and systems to support ongoing operation, and mentor others in these processes.
• Implement strategies to prevent interruptions, ensuring no maintenance windows are required for customers and users when resolving issues.
• Maintain expertise in owned components and systems to ensure effective troubleshooting and performance.
• Meet operational readiness expectations through design and implementation.
• Serve in operational support rotations, providing guidance in incident response and root cause investigations.

Compliance & Security:

• Implement robust security measures to protect data and applications in multi-tenant environments, including encryption techniques and access controls.
• Execute remediation plans to address identified security gaps.
• Ensure cloud infrastructure is in compliance with industry standards and regulations and that documentation is up to date.

Automation & Change Management:

• Develop and maintain automation scripts and tools (e.g., Infrastructure as Code (IaC)) to manage cloud infrastructure.
• Create and adhere to change management plans for patching, updating, and rolling back applications, and begin designing systems and components to allow for automation of these processes.
