Principal Engineer, Core Infrastructure

Kilt Platform EngineerAs 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.Within Kilt, the Observability & Supervision team owns how the platform sees itself and reacts. We build the systems that collect metrics and logs from every host and service, evaluate that signal against what healthy is supposed to look like, escalate to the right owner with the right context, and increasingly act on their own, whether that means scaling capacity, triggering recovery, or adjusting behavior based on the live state of upstream dependencies. This is real-time distributed systems work with strict latency budgets, where a decision has to be both fast and correct under partial information, because a wrong action taken across a fleet is worse than no action at all.For this role, we are looking for engineers with a passion for understanding how systems fail, not only how they work. You should be comfortable designing distributed control loops, reasoning about performance and correctness at scale, and owning a component from design through production operation. You should value simplicity, be direct in technical discussion, and be excited by problems where the answer is not yet known.We are a small, growing team with broad ownership and real autonomy. You will work with motivated, diverse people who care about doing things well, and you will have the support to do your best work in a workplace where you belong.ResponsibilitiesKey ResponsibilitiesSystem 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.Core ResponsibilitiesPlanning & Execution:Manages and coordinates moderately complex tasks, monitoring timelines and deliverables to ensure timely completion and adherence to requirements for a moderately-sized project or initiative. Efficiently delegates, monitors, and prioritizes work across multiple projects, providing technical oversight and adjusting plans to address shifts in resources or timelines.Collaboration & Partnership:Collaborates across the organization to align on expectations and achieve shared objectives. Leverages understanding of business leaders, stakeholders, and/or customers to ensure proposed solutions meet their needs. Supports inclusivity by actively seeking and listening to diverse perspectives, ensuring others feel heard and respected.Problem Solving:Identifies and addresses moderately complex issues by analyzing a wide range of data and/or information to identify solutions in accordance with standard practices. Proactively escalates unresolved or critical issues with a thorough assessment and suggests potential solutions. Reviews, contributes to, and documents problem solving strategies.Continuous Learning:Pursues learning opportunities to expand knowledge and skills and/or tools in new areas and stays abreast of the latest industry trends and best practices. Proactively seeks and leverages ongoing feedback and training to improve skills. Coaches and mentors junior team members, fostering continuous learning and knowledge sharing within and across teams.Continuous Improvement:Develops ideas, recommends updates, and/or collaborates on the implementation of process improvements to increase the efficiency and effectiveness of processes, protocols, and workflows across teams, and evaluates the impact on key stakeholders. Solicits feedback from others on ideas for alternative approaches and methods for continued improvement.Performance and Development:Contributes to the talent development pipeline by participating in candidate interviews, assessing candidates, and providing hiring recommendations.QualificationsDisclaimer:Certain U.S. based or U.S. customer or client-facing roles may be required to comply with applicable requirements, such as immunization/occupational health mandates, and/or drug testing requirements.
