Principal Engineer, Product Security

About the job

As the Principal Engineer for the Product Security team in Privacy, Safety, and Security, you will lead the architectural design for autonomous remediation, creating the "well-lit paths" and policy engines that allow Google to address both software vulnerabilities and systemic misconfigurations safely and at scale. This role requires navigating the complex trade-offs between security and reliability, ensuring that autonomous defense actions do not disrupt Google’s global services. As AI-powered vulnerability discovery begins to outpace traditional human-led remediation—a shift known as the Vuln-Apocalypse—Google requires a new paradigm for defensive security. In this role, you will lead the technical vision for Google’s security posture in an increasingly agentic world. You will bridge the gap between "agentic attackers" that identify risks at near-zero cost and the high-friction environment of manual production fixes.

The Core team builds the technical foundation behind Google’s flagship products. We are owners and advocates for the underlying design elements, developer platforms, product components, and infrastructure at Google. These are the essential building blocks for excellent, safe, and coherent experiences for our users and drive the pace of innovation for every developer. We look across Google’s products to build central solutions, break down technical barriers and strengthen existing systems. As the Core team, we have a mandate and a unique opportunity to impact important technical decisions across the company.

Responsibilities

• Lead the technical vision and multi-year roadmap for Google’s transition to autonomous defense, ensuring security posture can scale alongside AI-driven threats and the development of roadmaps for well-lit paths across tech stacks in these domains.
  
• Work with cross-functional leaders of the security domains to get alignment on the roadmaps and enable execution against those, and directly help lead the execution against strategy for some critical projects and areas, partnering with the relevant engineering and cross-functional directors and technical leaders.
• Develop a comprehensive strategy for Google's scanning and detection ecosystem, defining the optimal mix and integration of internally developed 1P scanning technology with acquisitions and products from the Cloud Security portfolio.
  
• Architect the "agentic defender" framework, creating the safety guardrails and policy engines that allow for the autonomous remediation of tier-3 and P1 vulnerabilities.
