Principal Security Researcher

About the role

The Principal Security Researcher position within Palo Alto Networks' Advanced Threat Prevention (ATP) team is dedicated to developing and delivering advanced threat detection capabilities. This role involves proposing and driving innovative technical ideas from concept to production, ensuring that the team stays ahead of evolving cyber threats.

Responsibilities

• Shape ATP detection strategy by identifying critical vulnerability, exploit, and attack technique areas requiring new or improved protections.
• Drive innovative detection ideas from concept to production, delivering measurable improvements in coverage, quality, speed, or scalability.
• Improve rapid response capability for zero-day, high-impact CVEs, and emerging attack vectors by guiding technical assessments, detection strategies, and release decisions.
• Enhance the quality and consistency of IPS protections by defining detection approaches, validation expectations, and technical review standards for complex cases.
• Expand the team's ability to deliver protections at scale through practical automation, detection pipeline improvements, and AI-assisted research workflows.
• Provide hands-on technical leadership to researchers or developers through direction, review, problem decomposition, and execution guidance.
• Influence cross-functional decisions with product, QA, engineering, and research partners to ensure detections are technically sound, customer-relevant, and production-ready.

Qualifications

• Deep hands-on experience in vulnerability research, exploit analysis, IPS/IDS detection, offensive security, or related fields.
• Proven ability to identify important technical problems, propose detection ideas, drive execution, and deliver measurable product or customer impact.
• Strong understanding of common vulnerability classes and exploit techniques, including memory corruption, injection, authentication bypass, path traversal, SSRF, RCE, XSS, SQL injection, CSRF, MITM, and DoS.
• Experience translating vulnerability or exploit understanding into production-quality IPS signatures, IDS detections, network detections, or other customer-facing protections.
• Strong programming or scripting skills for research automation, tooling, test generation, detection development, or pipeline improvements.
• Ability to lead complex technical work under ambiguity, guide other researchers or developers, and make sound technical decisions under time pressure.
• Experience using AI, ML, automation, or research tooling to improve security analysis, detection development, validation, or response workflows is highly desirable.
• Foundational understanding of AI security scenarios or AI-assisted security workflows is a plus.
• Strong communication skills with the ability to influence technical direction across research, product, QA, and engineering partners.
