Principal Security Engineer

Do you thrive on the leading edge of cloud technology and security? At Oracle Cloud Infrastructure (OCI), we are building and operating a suite of massive scale, integrated cloud services in a broadly distributed, multi-tenant cloud environment. OCI is providing best-in-cloud products that meet the needs of customers who are tackling some of the world's biggest challenges.

The OCI Core Services organization is the engineering and operations backbone of Oracle Cloud Infrastructure. It's responsible for the design, build, and run-time delivery of the foundational IaaS building blocks—Compute, Networking, and Block Volume—that every higher-level OCI service depends on. This is a global footprint, with hundreds of thousands of network devices supporting millions of servers, connected over a mix of dedicated backbone infrastructure and the Internet.

As a Principal Security Engineer, you will be the technical security leader for OCI's foundational components. You will advise engineering organizations on secure design, threat modeling, and security architecture of new features; establish security guardrails; design new internal security processes and tooling; and partner closely with product, engineering, and operations organizations to embed security at every layer of our global cloud platform.

This role offers the opportunity to:

• Shape the security architecture of one of the world's largest cloud providers
• Work with proven technical leaders and take on bleeding-edge infrastructure challenges
• Drive security initiatives that impact millions of customer workloads
• Lead security design for enterprise-grade cloud infrastructure
• Collaborate across teams to implement security at scale

The ideal candidate will bring deep expertise in cloud security, demonstrated experience building secure systems at scale, and the ability to influence technical direction through clear communication and technical leadership.
