About the role

Oracle's Core Infrastructure group builds and operates scalable, elastic distributed systems for cloud-scale services, with emphasis on performance, reliability, security, and operational excellence. The role is a principal-level engineering position focused on system architecture, fault tolerance, telemetry, incident response, and infrastructure automation. You will define scalability requirements and SLOs, design fault-tolerant services supporting zero-downtime upgrades, resolve complex production issues, and mentor engineers.

What you will do

  • 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.
  • 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.

What the employer is looking for

  • 7+ years of industry experience working on commercial or open-source software.
  • Strong fluency in C++ or Java or similar modern languages
  • Excellent problem-solving skills and a deep understanding of Computer Science fundamentals, including data structures, algorithms, and distributed systems.
  • Experience with cloud infrastructure (AWS/GCP/Azure) and build control plane systems for cloud scale
  • Strong systems programming skills, including experience with multi-threading and concurrency.
  • A solid foundation in distributed systems concepts (e.g., consistency, scaling, failure recovery).
  • Experience with implementation testing, debugging, and documentation, specifically within a Linux development environment.
  • BS in Computer Science; Masters preferred
  • Intense curiosity, willingness to question and passion for making systems
  • Experience designing architectures that demonstrate deep technical depth in one area, or span many products, to enable high availability, scalability, market-leading features and flexibility to meet future business demands

Preferred qualifications

  • Experience as technical lead on a large scale cloud service
  • Hands-on experience developing and maintaining services on a public cloud platform (e.g., OCI, AWS, Azure)
  • Experience working on Kubernetes
  • Knowledge of Infrastructure as Code (IAC) languages, preferably Terraform
  • Strong knowledge of databases (SQL and NoSQL)
  • Strong knowledge of Cloud Networking (OSI layers, HTTP, DNS, TCP/IP.)
  • Knowledge of Linux internals, Linux/Unix troubleshooting skills
  • Familiarity with host virtualization technologies (KVM, Containers, Docker, etc.)
  • Able to effectively communicate technical ideas verbally and in writing (technical proposals, design specs, architecture diagrams and presentations)
  • Experience with hiring, mentorship and raising the talent bar across the organization

Benefits and support

  • Compensation and benefits are detailed in the job posting
