Senior Principal Software Engineer, Core Infrastructure

Oracle Cloud Infrastructure (OCI) Compute delivers bare metal and virtual machine instances - CPU and GPU - at global scale. We are hiring a Senior Principal Software Engineer to design, build, and operate OCI Compute control plane services, with a focus on Imaging and Container Registry. In this role, you will lead complex technical projects and deliver secure, highly available, multi-tenant distributed services that scale across OCI regions. You will combine hands-on development with sound architectural judgment, collaborate with partner teams, and improve service reliability, performance, and operational efficiency. In this role, you will: • Design, implement, and operate resilient distributed services that support multi-tenancy, horizontal scaling, predictable performance, and cost efficiency. • Lead technical projects within Imaging and Container Registry, translating requirements into designs, implementation plans, and production-ready capabilities. • Collaborate with Compute, Storage, Networking, Oracle Kubernetes Engine (OKE), and OCI Functions teams to deliver platform features and resolve technical dependencies. • Apply secure-by-default design principles, including tenant isolation, authentication, authorization, and secure image and artifact lifecycle management. • Improve service-level objectives for availability, latency, and durability through observability, automation, capacity planning, and recovery mechanisms. • Own features and service components throughout their lifecycle, including design, implementation, testing, deployment, on-call support, and continuous improvement. • Investigate complex production issues, lead root cause analysis for owned components, and implement durable fixes. • Mentor engineers through design discussions, code reviews, and troubleshooting while strengthening the team’s engineering practices. • Contribute technical proposals and effort estimates to the service roadmap, partnering with engineering leaders and product management to prioritize customer needs.
