The role emphasizes on-site work in Nashville, with relocation assistance potentially available.

Qualifications

• Bachelor's or master's degree in Computer Science, Computer Engineering, or related field, or equivalent practical experience.
• 7+ years of professional software-engineering experience on large-scale distributed systems or cloud infrastructure.
• Strong experience designing and operating highly available, scalable, fault-tolerant distributed systems.
• Proficiency in Java, C++, C#, or Go.
• Deep understanding of distributed-systems design, data structures, algorithms, OS, networking, and secure software-development practices.
• Experience with system-level test automation and production incident response.
• Demonstrated experience leading or influencing technical architecture and mentoring engineers.
• Strong problem-solving, communication, and cross-functional collaboration skills.

Responsibilities

• Lead the design, implementation, and ongoing evolution of core distributed systems and data-plane services at hyperscale.
• Define scalability, elasticity, durability, and availability requirements for owned components and ensure designs meet them.
• Optimize high-throughput data paths for large-scale retrieval, storage, and processing using distributed state, replication, and synchronization patterns.
• Design fault-tolerant systems that support in-service updates through redundancy, automatic failover, and recovery-oriented design.
• Apply distributed-systems tradeoffs for network partitions and reliability, including load shedding, throttling, retries, and timeouts.
• Establish service-level objectives, KPIs, telemetry, dashboards, and proactive alerting for critical systems.
• Design and lead performance, load, fault-injection, and brownout testing to validate correctness, resilience, and operational readiness.
• Lead production incident diagnosis and recovery, guide root-cause analysis, and mentor engineers in operational excellence.
• Build and improve Infrastructure as Code and operational automation for safe patching, updates, rollbacks, and change management.
• Apply robust security controls for multi-tenant cloud infrastructure, including encryption, access controls, and compliance readiness.

Job description

Oracle Cloud Infrastructure (OCI) delivers mission-critical applications for leading enterprises worldwide. Our cloud offers hyperscale, multi-tenant services deployed across more than 50 regions globally. OCI continues to expand beyond traditional public-cloud boundaries to support dedicated, hybrid, and multicloud solutions, edge computing, and more.

As a Principal Core Infrastructure Engineer, you will lead the design and evolution of foundational distributed systems behind OCI. You will build highly scalable, elastic, and fault-tolerant services for high-volume data retrieval, storage, and processing, and set the technical direction for their reliability, correctness, security, and operational readiness.

This position is office-based and requires onsite presence in Nashville, Tennessee. Relocation assistance may be available in accordance with Oracle's relocation policies.

Internal Responsibilities

What You'll Do

• Lead the design, implementation, and ongoing evolution of core distributed systems and data-plane services at hyperscale.
• Define scalability, elasticity, durability, and availability requirements for owned components and ensure designs meet them.
• Optimize high-throughput data paths for large-scale retrieval, storage, and processing using distributed state, replication, and synchronization patterns.
• Design fault-tolerant systems that support in-service updates through redundancy, automatic failover, and recovery-oriented design.
• Apply sound distributed-systems tradeoffs for network partitions and reliability, including load shedding, throttling, rate limiting, retries, and timeouts.
• Establish service-level objectives, key performance indicators, telemetry, dashboards, and proactive alerting for critical systems.
• Design and lead performance, load, fault-injection, and brownout testing to validate correctness, resilience, and operational readiness.
• Lead production incident diagnosis and recovery, guide root-cause analysis, and mentor engineers in operational excellence.
• Build and improve Infrastructure as Code and operational automation that enable safe patching, updates, rollbacks, and change management.

• Apply robust security controls and remediation practices for multi-tenant cloud infrastructure, including encryption, access controls, and compliance readiness.

What You'll Bring

• Bachelor's or master's degree in Computer Science, Computer Engineering, or a related field, or equivalent practical experience.
• 7+ years of professional software-engineering experience, with demonstrated impact on large-scale distributed systems or cloud infrastructure.
• Strong experience designing and operating highly available, scalable, fault-tolerant distributed systems.
• Proficiency in one or more object-oriented or systems programming languages, such as Java, C++, C#, or Go.
• Deep understanding of distributed-systems design, data structures, algorithms, operating systems, networking, and secure software-development practices.
• Experience with system-level test automation, performance/load testing, reliability engineering, and production incident response.
• Demonstrated experience leading or influencing technical architecture and mentoring engineers.

• Strong problem-solving, communication, and cross-functional collaboration skills.

Preferred Qualifications

• Experience with Oracle Cloud, AWS, Azure, Google Cloud, or other large-scale cloud platforms.
• Experience with data-plane platforms, distributed storage, microservices, replication, state management, or high-throughput data processing.
• Experience defining SLOs, building observability systems, and operating services in a 24x7 production environment.
• Experience with Infrastructure as Code, service automation, security controls, and compliance requirements for cloud infrastructure.
