Senior AI Security Engineer - Build Secure AI Platforms

Palo Alto Networks, Inc.; Santa Clara (CA); On-site; USD 152,000 - 246,000; Full time

Job summary

Palo Alto Networks is seeking an AI security engineer to design reference architectures and AI-driven security services for secure product development.

You will build reusable libraries and guardrails, develop automated testing to uncover AI vulnerabilities, and translate threat models into concrete engineering requirements. The role emphasizes hardening the platform, governance of internal tooling, and collaboration across teams.

Qualifications

• Deep engineering expertise: 4–6+ years designing and securing complex software.
• Architecture & threat analysis: evaluate data flows, permissions, and trust boundaries to spot weaknesses.
• Strategic execution: turn complex security risks into concrete product features.
• Automation-first approach: build reusable tools, secure libraries, and automated test patterns.
• Practical knowledge of prompt injection testing, AI red teaming, and model safety.
• Familiarity with enterprise SaaS requirements (audit logs, data residency, encryption).
• Background in developing internal tools, CI pipelines, MCP integrations, or coding-agent guardrails.
• Active participation in security community via open-source work or vulnerability reports.

Responsibilities

• Design AI security reference architectures and build AI-driven security services for seamless use in product development.
• Build reusable libraries and guardrails to make secure implementation the default standard, reducing systemic risk across engineering teams.
• Develop automated testing suites to identify and mitigate AI-specific vulnerabilities, such as prompt injection, indirect instruction following, and unsafe workspace mutations.
• Translate complex threat models into clear engineering requirements, production security checks, and launch criteria.
• Analyze production signals and incident reports to continuously harden the platform and optimize security architectures.
• Govern the safe use of internal tooling (coding agents, automation hooks, MCP integrations) to maintain a healthy balance between developer productivity and security.
