The Oracle Cloud Infrastructure (OCI) team builds and manages a suite of massive scale, integrated cloud services in a broadly distributed, multi-tenant cloud environment. OCI is committed to providing the best in cloud products that meet the needs of our customers who are tackling some of the world’s biggest challenges.

• 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.
