Principal Core Infrastructure Engineer

Oracle•Seattle, WA

About The Position

The Principal Core Infrastructure Engineer leads the development and begins architecting components of scalable, elastic distributed systems. The role defines scalability requirements for owned components, optimizes code and data paths for high-throughput, hyperscale workloads, and uses data-plane platforms for large-scale retrieval, storage, and processing. The engineer designs fault-tolerant systems that support in-service upgrades through redundancy, replication, and failover. They address network partitions and unreliability using appropriate consistency, availability, load-shedding, throttling, and rate-limiting strategies, while meeting service-level objectives. The role establishes KPIs and telemetry, builds dashboards and alerts, and designs validation scenarios—including fault injection and brownouts—as well as replication and synchronization mechanisms that support correctness and durability. The position also involves proactive production troubleshooting, incident response, mentoring, operational readiness, security remediation, compliance documentation, and infrastructure automation. The engineer develops infrastructure-as-code and other tools, and follows change-management plans for safe patching, updates, and rollbacks. They coordinate moderately complex work, collaborate across the organization, contribute to process improvements and talent development, and coach junior team members. Oracle lists a U.S. hiring range of $114,600 to $234,600 per year. The role may also be eligible for bonus, equity, and compensation deferral. Oracle describes a comprehensive benefits package for U.S. employees.

Responsibilities

Lead development and begin architecting scalable distributed-system components that support horizontal and vertical scaling, including distributed state management.
Optimize code and systems for large-scale data processing and high-throughput workloads.
Define scalability requirements for owned components and ensure design and implementation meet them.
Design systems that scale elastically and use data-plane platforms for large-scale retrieval, storage, and processing.
Design performance and load testing.
Design fault-tolerant components and systems that support in-service updates through redundancy, replication, and automatic failover.
Design systems to handle service disruptions such as network partitions, and implement approaches for network unreliability including load-shedding, throttling, and rate-limiting.
Design durable systems that adhere to service-level objectives and set availability and durability expectations for other computing services in the department.
Define KPIs and telemetry, and build dashboards, telemetry systems, and alerts to monitor component and system health.
Design and implement functional and correctness requirements for features and systems.
Design complex correctness test scenarios, such as fault-injection and brownout testing, and implement data replication and synchronization to maintain integrity and availability.
Diagnose, debug, and resolve issues in active systems; mentor others in troubleshooting; and maintain expertise in owned components.
Develop strategies to prevent service interruptions and avoid customer-facing maintenance windows when resolving issues.
Meet operational readiness expectations and participate in operational support rotations, including incident response and root-cause investigations.
Implement security measures for data and applications in multi-tenant environments, including encryption and access controls, and execute remediation plans for security gaps.
Maintain cloud-infrastructure compliance with industry standards and regulations and keep documentation up to date.
Develop and maintain automation scripts and tools, including infrastructure as code, to manage cloud infrastructure.
Create and follow change-management plans for patching, application updates, and rollbacks, and begin designing systems to automate these processes.
Coordinate moderately complex tasks, monitor project timelines and deliverables, delegate and prioritize work across projects, provide technical oversight, and adjust plans as needed.
Collaborate across the organization and consider business leaders', stakeholders', and customers' needs when proposing solutions.
Promote inclusivity by seeking and listening to diverse perspectives and ensuring others feel heard and respected.
Analyze information to identify solutions to moderately complex problems, escalate critical or unresolved issues with assessments and proposed solutions, and document problem-solving strategies.
Pursue learning and feedback, stay current with industry trends, and coach and mentor junior team members.
Recommend and help implement process improvements, solicit feedback on alternative approaches, and evaluate impact on stakeholders.
Participate in candidate interviews, assess candidates, and provide hiring recommendations.
