Principal Engineer, Core Infrastructure
About the role
As part of the TSO/AOCI organization, our mission is to build Kilt, the platform on which OCI services are built, deployed, and operated across every region. We are investing in core platform capabilities that let service teams focus on their product rather than on the undifferentiated work of running it at scale, and we are doing it with a small group of engineers concentrated on high-leverage, low-level systems.
Responsibilities
System Design & Architecture - System Scalability: 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.
System Design & Architecture - System Reliability Design: 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.
System Design & Architecture - System Reliability Performance: 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.
System Design & Architecture - Correctness / Availability: 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.
Operational Troubleshooting & Incident Management: 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.
Compliance & Security: 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.
Automation & Change Management: 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.
Qualifications
Passion for understanding how systems fail, not only how they work. Comfortable designing distributed control loops, reasoning about performance and correctness at scale, and owning a component from design through production operation.
Value simplicity, be direct in technical discussion, and be excited by problems where the answer is not yet known. Work in a small, growing team with broad ownership and real autonomy.
Benefits

Paid time off: Flexible Vacation is provided to all eligible employees assigned to a salaried (non-overtime eligible) position. Accrued Vacation is provided to all other employees eligible for vacation benefits. For employees working at least 35 hours per week, the vacation accrual rate is 13 days annually for the first three years of employment and 18 days annually for subsequent years of employment. Vacation accrual is prorated for employees working between 20 and 34 hours per week. Employees working fewer than 20 hours per week are not eligible for vacation.
11 paid holidays
Paid sick leave: 72 hours of paid sick leave upon date of hire. Refreshes each calendar year. Unused balance will carry over each year up to a maximum cap of 112 hours.
Employee Stock Purchase Plan
Financial planning and group legal
Voluntary benefits including auto, homeowner and pet insurance
Pay
Hiring Range in USD from: $114,600 - $234,600 per year. May be eligible for bonus, equity, and compensation deferral.
Schedule
The role will generally accept applications for at least three calendar days from the posting date or as long as the job remains posted.
