Minimum qualifications:

• Bachelor's degree in Computer Science, Computer Engineering, or equivalent practical experience.
• 15 years of professional software development experience, or 13 years with an advanced degree.
• Experience architecting, developing, and securing low-level systems software across the virtualization and operating systems stack (e.g., hypervisors such as KVM/Cloud Hypervisor/QEMU, Linux kernel internals, VMMs, firmware, or hardware-assisted virtualization).

Preferred qualifications:

• Advanced degree (Master's or PhD) in Computer Science, Computer Engineering, Cybersecurity, or a related technical field.
• 20 years of software engineering experience, with experience with industry leadership in cloud platform security, hypervisor security, hardware/CPU security, or operating system defense.
• Experience anticipating and defending against emerging adversarial capabilities, including AI/LLM-accelerated vulnerability discovery, automated exploit synthesis, and autonomous agentic threat vectors.
• Experience in cross-organizational technical leadership, executive communication, and building consensus across large, multi-disciplinary engineering organizations (Hardware/Silicon).
• Expertise in hardware-software security co-design, including CPU microarchitectural vulnerability mitigation (speculative execution, side-channel analysis), hardware root-of-trust, vTPM, and Confidential Computing.

About the job

As Principal Engineer for GCE Platform Security, you will serve as the premier technical authority, executive architect, and overall owner for the end-to-end security posture of Google Compute Engine (GCE) - protecting the foundational global infrastructure that powers Google Cloud, Core Google services, and advanced AI research labs and mission-critical enterprise workloads.

In this high-impact strategic role, your leadership spans the complete architectural continuum between the distributed Control Plane and the foundational Data Plane. Across the control plane, you will architect robust, scalable defenses for multi-tenant orchestration, resource lifecycle management, zero-trust identity and access boundaries, supply-chain integrity, and high-assurance compliance for regulated and public-sector cloud environments. Across the node data plane, you will lead deep systems security architecture across hypervisors, virtual machine monitors (VMMs), host operating systems, kernel subsystems, and hardware-level isolation mechanisms.

Crucially, you will navigate a rapidly transforming threat landscape shaped by the emergence of agentic threat vectors enabled through advanced LLMs, where automated, AI-driven vulnerability discovery and exploit generation compress attacker timelines to machine speed. You will lead proactive defense-in-depth across the platform - mitigating hardware and microarchitectural CPU vulnerabilities (e.g., speculative execution, transient execution side-channels, and address space isolation), eliminating memory safety exploitation risks across the virtualization stack, and advancing host deprivileging and zero-trust host architectures.

Furthermore, you will advocate for next-generation virtualization security designs - leveraging custom silicon for isolation, establishing multi-domain security boundaries, and architecting secure runtime substrates for next-generation AI workloads, high-density sandboxed execution environments, and massive accelerator clusters.

Google Cloud accelerates every organization's ability to digitally transform its business and industry. We deliver enterprise-grade solutions that leverage Google's cutting-edge technology, and tools that help developers build more sustainably. Customers in more than 200 countries and territories turn to Google Cloud as their trusted partner to enable growth and solve their most critical business problems.
Individual pay is determined by factors including job-related skills, experience, and relevant education or training.

Responsibilities

• Serve as the overall technical authority and executive owner for GCE Platform Security, defining and driving the multi-year security strategy across distributed global control planes and low-level node data planes.
• Formulate architectural and operational defenses to counter the rapid emergence of autonomous agentic threat vectors and LLM-assisted exploitation tools, establishing automated vulnerability discovery, proactive mitigation frameworks, and rapid incident response capabilities across the fleet.
• Architect robust, hardware-level defenses and isolation boundaries to eliminate and mitigate hardware CPU vulnerabilities, speculative execution side-channels, transient execution threats, and cross-tenant leakage
• Lead security defenses and privilege reduction across hypervisor technologies, virtual machine monitors (VMMs), host kernels, and low-level runtimes, implementing sandboxing and defense against virtualization escapes.
• Drive the architectural outlook for host security and isolation, advancing host deprivileging, zero-trust host architectures, hardware-assisted offloading of security and lifecycle functions.
