the team that builds and delivers the threat detection capabilities powering Palo Alto Networks’ Advanced Threat Prevention (ATP). The ATP detection team is responsible for decoding network protocols, identifying applications, and detecting threats across our enterprise customers’ networks. As a Principal Security Researcher, you will play a key technical leadership role in shaping how ATP detects and prevents real-world attacks. You will propose and drive innovative technical ideas from concept to production, own multiple projects or a broader technical area with measurable impact, and provide technical leadership to other researchers or developers. This is a hands-on leadership role: you are expected to define direction, make technical decisions, and contribute directly to vulnerability research, exploit analysis, and production detection work. Your Impact Shape ATP detection strategy by identifying important vulnerability, exploit, and attack technique areas where new or improved protections are needed. Drive innovative detection ideas from concept to production, delivering measurable improvements in coverage, quality, speed, or scalability. Improve rapid response capability for zero-days, high-impact CVEs, and emerging attack vectors by guiding technical assessment, detection strategy, and release decisions. Raise 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 closely related threat prevention work. Proven ability to identify important technical problems, propose detection ideas, drive execution, and deliver measurable product or customer impact. Deep 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. Strong ability to analyze vulnerability root cause, exploitability, PoC behavior, network traffic, protocol behavior, application-layer attack patterns, and detection tradeoffs. Experience translating vulnerability or exploit understanding into production-quality IPS signatures, IDS detections, network detections, or other customer-facing protections. Strong understanding of network protocols and application-layer behavior, especially HTTP, DNS, SMB, FTP, SMTP, TCP/UDP, TLS, and related protocols. 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. BS/MS in Computer Science, Computer Engineering, Cybersecurity, or related field, or equivalent professional experience.
