Core Infrastructure Engineer 2

About the Role

Oracle is seeking a Core Infrastructure Engineer 2 to implement and optimize components within existing distributed systems under guidance. This role involves applying basic scalability requirements, conducting performance/load testing, and configuring resiliency features to handle network variability. The engineer will build telemetry, alerts, and runbook-driven procedures, deliver scoped features and fault-injection tests, and assist in implementing basic data replication and synchronization. Participation in on-call rotations, troubleshooting using automation/IaC scripts, and adherence to change, security, and compliance procedures are also key aspects.

Key Responsibilities

• System Design & Architecture - System Scalability:

• Assist in the implementation of distributed system components that support horizontal and vertical scaling under senior engineer guidance.

• Optimize code segments and/or systems for large-scale data processing with senior engineer oversight.

• Implement scalability requirements for assigned components.

• Learn about data plane platforms for large-scale data retrieval, storage, and processing.

• Execute performance and load testing, with guidance.

• System Design & Architecture - System Reliability Design:

• Collaborate to build fault-tolerant components capable of withstanding in-service updates by learning about redundancy, replication, and automatic failover.

• Learn about recovery-oriented computing principles and assist in applying them to component designs.

• Configure and test retry mechanisms, circuit breakers, and timeouts to handle network unreliability, with guidance.

• System Design & Architecture - System Reliability Performance:

• Implement testing and alarming configurations to detect issues/failures.

• Support failure recovery by drafting and executing runbooks and operational procedures, under guidance.

• Help build dashboards, telemetry systems, and alerting mechanisms to monitor component health.

• System Design & Architecture - Correctness / Availability:

• Implement functional requirements and testing for assigned features within an existing system.

• Implement test scenarios (e.g., fault-injection, brown-out) to evaluate system correctness, under guidance.

• Help implement basic data replication and synchronization techniques to maintain data integrity and availability.

• Operational Troubleshooting & Incident Management:

• Assist in diagnosing and debugging system component issues to support ongoing operation, under supervision.

• Follow protocols to prevent interruptions, ensuring no maintenance windows are required for customers and users when resolving issues.

• Run basic automation scripts and tooling to troubleshoot operational issues.

• Participate in operational support rotations, assisting in incident responses and root cause investigations.

• Compliance & Security:

• Assist in implementing basic security measures to protect data and applications in multi-tenant environments, including encryption and access controls.

• Assist in executing remediation plans to address identified security gaps, under supervision.

• Support the creation and updating of documentation to ensure cloud infrastructure compliance with relevant industry standards and regulations.

• Automation & Change Management:

• Assist in maintaining basic automation scripts and tools (e.g., Infrastructure as Code (IaC)).

• Adhere to change management plans for patching, updating, and rolling back applications, under guidance.

Core Responsibilities

• Planning & Execution:

• Track timelines with minimal supervision, ensuring timely completion aligned with project requirements.

• Prioritize and adjust work as resources or timelines change, with some guidance.

• Collaboration & Partnership:

• Collaborate within the team to understand expectations and achieve shared objectives.

• Leverage a foundational understanding of business, stakeholder, and/or customer needs to build partnerships with limited guidance.

• Actively listen and ask questions to enhance collaboration.

• Build a basic understanding of business, stakeholder, and/or customer needs with guidance.

• Problem Solving:

• Identify and address issues, escalating problems to senior staff as needed per standard procedures.

• Compile and review data from multiple sources to troubleshoot standard and non-standard errors.

• Continuous Learning:

• Seek opportunities to gain knowledge and learn new skills/tools aligned with industry trends and best practices.

• Utilize feedback and training to improve skills.

• Participate in a culture of continuous learning and knowledge sharing.

• Continuous Improvement:

• Implement updates to processes, protocols, and workflows to increase efficiency and effectiveness as directed, with some guidance.

• Contribute to ideation for future process improvements.
