Join Oracle Cloud Infrastructure (OCI) as a Principal Core Infrastructure Engineer, focusing on Site Reliability Engineering for SmartNICs. This role is crucial for maintaining and enhancing the services that manage SmartNICs across our cloud infrastructure.

You will ensure the reliability of card provisioning, configuration, deployment, health monitoring, and recovery throughout the hardware lifecycle. The position blends software engineering, systems troubleshooting, and production operations, requiring close collaboration with software, networking, firmware, hardware, and data center teams to ensure a healthy and available distributed fleet.

Key responsibilities include operating and enhancing services for SmartNIC discovery, provisioning, configuration, upgrades, and decommissioning. You will define and track service-level objectives for management services and fleet operations. Building robust observability for card health, lifecycle transitions, firmware rollout progress, and operational failures is essential.

Troubleshooting issues across management services, Linux systems, networking, and hardware interfaces is a core part of the role. Developing automation for detecting unhealthy cards, collecting diagnostics, and performing safe remediation is expected. You will also improve firmware and software deployments through staged rollouts, health validation, and controlled concurrency.

Designing reliable lifecycle workflows that handle various failure scenarios, participating in on-call rotations, and driving corrective actions are key. Partnering with engineering teams to address recurring failures and enhance serviceability, resilience, and operational readiness is vital. Maintaining and validating runbooks and recovery procedures, along with planning for fleet growth and operational scalability, are also crucial aspects of this position.

We seek candidates with proven experience in site reliability engineering, systems engineering, production engineering, or distributed infrastructure operations. Strong Linux troubleshooting skills, encompassing processes, memory, storage, networking, and system logs, are required.

Proficiency in Python, shell scripting, or another language for building production services and automation is necessary. A solid understanding of distributed systems, APIs, asynchronous workflows, and failure recovery is expected. Knowledge of networking fundamentals, including TCP/IP, routing, switching, and packet-level troubleshooting, is also essential.

Experience with monitoring, alerting, incident response, and root-cause analysis is required. The ability to investigate problems spanning software and hardware boundaries, coupled with clear communication and effective coordination during production incidents, is paramount. Preferred qualifications include experience with SmartNICs, DPUs, firmware lifecycle management, operating large hardware fleets, network virtualization, and designing safe fleet-wide changes.
