Principal Core Infrastructure Engineer, OCI Planning & Capacity

Location: Nashville, TN — onsite 5 days/week. Relocation assistance is available; this is not a remote position. Job Summary Leads development and begins architecting components of scalable, elastic distributed systems. Defines and enforces scalability requirements for owned components; optimizes code and data paths for high ‑ throughput, hyper ‑ scale workloads; and leverages data plane platforms for large ‑ scale retrieval, storage, and processing. Designs fault ‑ tolerant, in ‑ service ‑ upgradable systems using redundancy, replication, failover, and policies for partitions, applying load ‑ shedding, throttling, and rate ‑ limiting to handle network unreliability while meeting SLOs. Establishes KPIs and telemetry; builds proactive dashboards and alerts; and designs complex validation (fault injection, brownouts), replication, and synchronization for correctness and durability. Proactively diagnoses and resolves production issues, mentors peers, and ensures operational readiness. Implements robust security controls, executes remediation, maintains compliance documentation, and develops IaC and automation that enable safe patching, updates, and rollbacks within change ‑ management plans. About the Team & Organization Oracle Cloud Infrastructure is seeking a motivated Principal Core Infrastructure Engineer to join the OCI Infrastructure Planning and Capacity Management organization. The OCI Infrastructure Planning and Capacity Management team builds software solutions that improve how OCI manages infrastructure capacity, sources resources, and plans for future demand. Our work spans planning and forecasting services, infrastructure sourcing workflows, process automation, data integration, and operational reporting. We focus on improving decision quality, increasing operational visibility, and reducing manual effort across engineering, operations, supply chain, and finance. In this role, you will design, develop, and maintain backend services, APIs, and workflow automation solutions that support critical infrastructure planning and capacity management processes. You will own technical designs and service implementations, contribute to architectural decisions, and collaborate across engineering teams to deliver scalable, reliable production systems. You will work on both new capabilities and enhancements to existing systems, applying strong software engineering fundamentals and modern development practices to solve complex technical and operational challenges. You will also help improve system architecture, performance, reliability, and operational efficiency across infrastructure planning and capacity management solutions. Key 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 Design & Architecture - 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, an…
