Principal Core Infrastructure Engineer, AI Infrastructure

Oracle•Nashville, TN

13d•$114,600 - $234,600

About The Position

OCI (Oracle Cloud Infrastructure) AI Infrastructure is at the forefront of building a cutting-edge, ultra-high-performance GPU platform designed to support AI/ML/HPC workloads. This is your chance to be part of the AI revolution, creating systems that allow customers to scale from tens to thousands of GPUs without compromising performance. Our team is responsible for designing and developing fundamental architectural changes for GPU delivery, health monitoring, triage automation, and diagnostic services. These are essential for running distributed AI/ML/HPC workloads across thousands of GPUs, leveraging technologies like RoCE and Infiniband.

Deep understanding of operating systems, computer networks, and high-performance applications
6+ years’ experience delivering and operating large-scale production systems (1000+ server instances)
Proficient in one programming language(java/python/c/c++/goLang/shell scripting)
Systematic problem-solving approach, strong communication skills, a sense of ownership, and drive.
Proven ability to deliver products and experience with the full software development lifecycle

Nice To Haves

Strong background in Linux systems
Familiarity with system-level architecture, data synchronization, fault tolerance, and state management.
General enterprise storage, networking, or computing experience
Experience with Server/GPU hardware architecture and system management.
Experience with Infiniband or RoCE networking
Hands-on experience designing, developing, and operating public cloud service data planes
Good understanding of databases and SQL (MySQL) and caching technologies (Redis, Memcache etc)

Responsibilities

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.
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.
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.
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.
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.
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.
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.
Manages and coordinates moderately complex tasks, monitoring timelines and deliverables to ensure timely completion and adherence to requirements for a moderately-sized project or initiative. Efficiently delegates, monitors, and prioritizes work across multiple projects, providing technical oversight and adjusting plans to address shifts in resources or timelines.
Collaborates across the organization to align on expectations and achieve shared objectives. Leverages understanding of business leaders, stakeholders, and/or customers to ensure proposed solutions meet their needs. Supports inclusivity by actively seeking and listening to diverse perspectives, ensuring others feel heard and respected.
Identifies and addresses moderately complex issues by analyzing a wide range of data and/or information to identify solutions in accordance with standard practices. Proactively escalates unresolved or critical issues with a thorough assessment and suggests potential solutions. Reviews, contributes to, and documents problem solving strategies.
Pursues learning opportunities to expand knowledge and skills and/or tools in new areas and stays abreast of the latest industry trends and best practices. Proactively seeks and leverages ongoing feedback and training to improve skills. Coaches and mentors junior team members, fostering continuous learning and knowledge sharing within and across teams.
Develops ideas, recommends updates, and/or collaborates on the implementation of process improvements to increase the efficiency and effectiveness of processes, protocols, and workflows across teams, and evaluates the impact on key stakeholders. Solicits feedback from others on ideas for alternative approaches and methods for continued improvement.
Contributes to the talent development pipeline by participating in candidate interviews, assessing candidates, and providing hiring recommendations.
