37d•$79,200 - $209,500

About The Position

OCI (Oracle Cloud Infrastructure) AI Infrastructure is building an ultra-high-performance GPU platform for AI/ML/HPC workloads, enabling customers to scale from tens to thousands of GPUs without compromising performance. The Senior Core Infrastructure Engineer designs, implements, and optimizes distributed-system components with an emphasis on scalability, resiliency, and operability. The role delivers features and performance/load testing, uses data-plane platforms and distributed-state tools for high-volume retrieval, storage, and processing, and reviews implementations for scalability. The engineer builds fault-tolerant systems using redundancy, replication, automatic failover, retries, circuit breakers, and timeouts. The role proactively detects and mitigates issues through tests, alarms, dashboards, and telemetry; prepares runbooks; and participates in operational support, incident response, and root-cause investigations. It also involves replication and synchronization, troubleshooting and maintenance automation and infrastructure as code, security controls, compliance, change management, and documentation.

Responsibilities

Implement and contribute to distributed-system components that support horizontal and vertical scaling, including use of distributed-state management tools.
Optimize code and systems for large-scale data processing.
Implement scalability requirements for assigned components and review team members’ implementations.
Use data-plane platform components for large-scale data retrieval, storage, and processing.
Implement performance and load testing.
Collaborate on fault-tolerant components that withstand in-service updates through redundancy, replication, and automatic failover.
Apply recovery-oriented computing principles and implement retries, circuit breakers, and timeouts to handle service disruptions and network unreliability.
Implement tests and alarm configurations to detect and address issues and failures proactively.
Draft and execute runbooks and operational procedures to support failure recovery.
Build and customize dashboards, telemetry systems, and alerting mechanisms to monitor component health.
Design and implement feature requirements and testing within existing systems, including fault-injection and brown-out test scenarios.
Implement data replication and synchronization techniques to maintain data integrity and availability.
Diagnose, debug, and resolve system-component issues and implement strategies to avoid customer maintenance windows.
Design and implement automation scripts and tooling for troubleshooting operational issues.
Participate in operational support rotations, incident response, and root-cause investigations.
Apply security measures for multi-tenant environments, including encryption and access controls, and implement remediation plans.
Work with the team to maintain compliance with relevant industry standards and regulations and keep documentation current.
Maintain automation scripts and tools, including infrastructure as code, for cloud infrastructure management.
Follow change-management plans for application patching, updates, and rollbacks.
