## Description

We are looking for hands-on, senior technical leaders with deep expertise and passion for distributed systems, databases, storage infrastructure, transaction processing, and highly available services. As a Software Engineer on this team, you will help define and build the next generation of OCI control-plane storage. You will work on challenging problems such as read/write scalability, strict serializability, multi-version concurrency control, data-plane architecture, operational automation, performance isolation, resiliency, and global service growth.This is an opportunity to influence the architecture of a critical OCI platform service, mentor engineers, drive large technical initiatives, and build systems that directly impact the reliability and scalability of Oracle Cloud. The team is growing, the technical challenges are deep, and the work is central to OCI's ability to operate cloud services safely at massive scale.
Responsibilities:

 * Lead the design and evolution of foundational cloud infrastructure services that manage critical control-plane metadata and state for large-scale OCI services.
 * Architect and build highly available, strongly consistent, low-latency distributed systems with a focus on correctness, durability, scalability, and operational excellence.
 * Drive major technical initiatives across the full lifecycle, from architecture and implementation to safe rollout, production operations, and continuous improvement.
 * Improve service scalability, performance, and predictability through better data-plane architecture, transaction processing, caching, throttling, capacity planning, and failure recovery.
 * Build and operate resilient multi-tenant systems with strong observability, automation, alarms, dashboards, deployment safety, and incident prevention mechanisms.
 * Mentor engineers, raise the engineering bar through design and code reviews, and establish best practices for distributed systems, production readiness, and operational excellence.
