About the role
Oracle Cloud Infrastructure's Block Storage Service builds scalable, highly available storage for cloud workloads. The team works on distributed systems, virtualized infrastructure, and hyperscale storage services. This Principal Core Infrastructure Engineer will lead design and development of major Block Storage components, including performance, reliability, security, automation, and operational excellence.
What you will do
- Design and architect scalable distributed systems: Lead the design and implementation of major Block Storage components that support horizontal and vertical scaling, elasticity, distributed state management, and large-scale data processing.
- Drive performance and efficiency at scale: Optimize software, data paths, and system interactions for high-throughput, hyperscale workloads; establish scalability requirements and develop appropriate performance and load-testing strategies.
- Engineer highly reliable and durable services: Design fault-tolerant systems using redundancy, replication, synchronization, and automated failover while enabling in-service upgrades and minimizing customer-visible disruption.
- Design for distributed-systems failure modes: Develop systems that behave predictably during network partitions, infrastructure failures, and traffic spikes by applying appropriate consistency and availability models, load shedding, throttling, and rate limiting.
- Ensure correctness, availability, and observability: Define functional and correctness requirements, establish KPIs and telemetry, build dashboards and alerts, and create sophisticated validation strategies such as fault injection and brownout testing.
- Own operational excellence: Proactively diagnose, debug, and resolve complex production issues; participate in operational support rotations; conduct or guide root-cause investigations; and ensure systems meet operational-readiness standards.
- Strengthen security and compliance: Implement security controls for multi-tenant cloud environments, including encryption and access controls; remediate identified vulnerabilities and maintain infrastructure and supporting documentation in accordance with applicable requirements.
- Advance automation and engineering practices: Develop Infrastructure as Code (IaC), tooling, and automated workflows for provisioning, patching, updating, deployment, and rollback while mentoring engineers and contributing to strong engineering practices across the team.
Skills used in this role
What the employer is looking for
- 10+ years of software engineering experience, including experience designing and delivering large-scale, highly available distributed systems or backend services.
- Strong hands-on programming experience developing production-quality software in Java, C++, or comparable systems/backend programming languages.
- Experience with scripting or automation languages such as Python.
- Strong knowledge of data structures, algorithms, concurrency, multithreading, and distributed systems fundamentals.
- Demonstrated experience designing systems for scalability, high availability, fault tolerance, durability, and performance.
- Working knowledge of networking fundamentals and protocols, including TCP/IP, HTTP, and common network architectures.
- Strong production troubleshooting, debugging, performance analysis, and performance-tuning capabilities.
- Ability to independently own complex technical components while collaborating effectively in an agile engineering environment.
- Career Level - IC4
Preferred qualifications
- Experience building or operating multi-tenant cloud infrastructure.
- Experience with virtualized storage infrastructure, block storage, storage systems, or data-management platforms.
- Experience designing replication, synchronization, consistency, and failover mechanisms in distributed systems.
- Experience with cloud service observability, including telemetry, metrics, dashboards, alerting, and SLO-based operations.
- Experience designing and executing fault-injection, brownout, resilience, performance, or large-scale load tests.
- Experience with Infrastructure as Code (IaC) and automated cloud infrastructure provisioning, deployment, patching, and rollback.
- Knowledge of cloud security practices, including encryption, access controls, vulnerability remediation, and compliance requirements.
- Experience participating in production support rotations, incident response, and root-cause analysis for large-scale services.
- Demonstrated ability to mentor engineers, influence technical direction, and contribute to architectural decisions across teams.
