Job Summary

Your Career

With Prisma AIRS, Palo Alto Networks is building the world's most comprehensive AI security platform. Organizations are increasingly building complex ecosystems of AI models, applications, and agents, creating dynamic new attack surfaces with risks that traditional security approaches cannot address. In response, Prisma AIRS delivers model security, posture management, AI red teaming, and runtime protection. Our customers can confidently deploy AI-driven innovation while ensuring a formidable security posture from development through runtime.

The Platform Infrastructure team is the engine behind this mission. We provide the foundational cloud infrastructure and a smooth interface that abstracts away the complexities of global networking and infosec for our product teams. We are seeking a Principal Infrastructure / Security Engineer to own the intersection of platform infrastructure and product security.

In this hybrid role, you will lead the "shift-left" security strategy, building internal platform tools that allow our engineers to ship secure-by-default software. You will be the primary technical interface between the AIRS organization and central infosec.

This role is in office 3 days a week. Specify your preference of our downtown Seattle Washington office or our Santa Clara, California HQ campus.

Our Stack

Our platform is built on a modern, cloud-native foundation centered around Kubernetes. We value deep expertise in a few core areas and a strong desire to master the technologies that drive our platform forward.

Cloud & Orchestration

• GCP (primary), Kubernetes, AWS, Containerization tools

• Build the "Security Paved Road": Act as a force multiplier by integrating security tooling directly into our internal developer platform and CI/CD pipelines.
• Abstract Infosec Complexity: Serve as the strategic point of contact for central Infosec, translating their requirements into automated infrastructure patterns so product teams don't have to.
• Govern Release Integrity: Define and enforce security standards for Prisma AIRS, ensuring every new feature meets launch requirements and compliance standards before reaching customers.
• Scale Foundational Infra: Work with the infrastructure team to embed security and permissions management into our core GCP and Kubernetes foundations.
