Staff Product Security Engineer, PSIRT

Job description

It all started when engineer Fred Luddy wrote code that automated a tedious task for his coworker, Phyllis. She cried tears of joy. That moment inspired Fred to build a company that could do that for everyone—freeing people from busywork so they could focus on meaningful work. Today, ServiceNow is the AI control tower for business reinvention. Our ServiceNow AI platform brings together any AI, any data, and any workflow— helping 85% of the Fortune 500® work smarter, faster, and better. We're building an AI-native culture where technology and talent are unstoppable together. And we're just getting started. Join us to put AI to work for people.   ServiceNow seeks a staff-level product security engineer to serve as a senior technical authority within the Product Security Incident Response Team (PSIRT). PSIRT is ServiceNow's awareness, response, and investigation capability for post-release vulnerabilities in ServiceNow-developed products and service offerings.  This role is for a recognized expert who can operate independently and as part of a team on the most significant security issues facing the platform—vulnerabilities that require evaluating intangibles. You will lead deep-dive investigations, coordinate resolution across engineering, product, and release teams, and demonstrate calm, decisive leadership during significant security events.  This is a role for someone who already understands product development cycles and the engineering and product relationships that drive them—and will use that fluency to lead fixes to completion under incident pressure. You will help shape how ServiceNow responds to product security vulnerabilities at scale and the technical rigor of the entire response capability.  What you get to do in this role:       Lead Through Significant Security Events  • Demonstrate technical and organizational leadership during these events—bringing structure and clear decision-making under pressure.  • Partner with incident commanders, business information security leadership, engineering, and customer-facing teams to maintain clear ownership, workstream prioritization, and hand-offs during these events.  Reduce Exposure Window  • Drive coordinated response across affected releases, balancing risk and remediation feasibility.  • Leverage an understanding of product development cycles and engineering/product partnerships to move fixes through the release pipeline without stalling on organizational boundaries.  • Verify fix completeness and guard against incomplete mitigations before release.  CVE & Coordinated Disclosure Process  • Contributed to ServiceNow's CVE disclosure process for incidents you own—CVE assignment, scoring, advisory content, and publication timing.  • Conduct technical accuracy reviews of external advisories, researcher write-ups, and joint disclosure content to ensure correctness before publication.  Pursue After-Action Outcomes & Continuous Improvement  • Author root cause analyses and drive lessons learned to closure following product security incidents.  • Participate in retrospectives following significant product security events, translating findings into concrete process and technical improvements.  • Contribute to partner teams tracking product security risk themes and trends across the portfolio.  • Contribute to SDLC improvement areas, feeding incident learnings upstream into secure development practices.  To be successful in this role you have: • Experience in leveraging or critically thinking about how to integrate AI into work processes, decision-making, or problem-solving. This may include using AI-powered tools, automating workflows, analyzing AI-driven insights, or exploring AI's potential impact on the function or industry. • Minimum 8 years of related experience with a Bachelor's degree; or 6 years with a Master's degree; or a PhD with 3 years of experience; or equivalent experience.  • Minimum 4 years of auditing source code for security vulnerabilities.  • Demonstrated leadership during significant security events or major incidents, with willingness to participate in on-call.  • Ability to read and comprehend Java and JavaScript code.   • Strong understanding of common Java and JavaScript vulnerabilities.   • Proficiency in scripting in both Python and JavaScript for data gathering, processing, and visualization.   • Development of proof-of-concept exploits for web application vulnerabilities.   • Written and verbal communication of complex security risk clearly to both technical teams and leadership.  • Experience with leading fix implementation and release coordination across engineering, product, and test/release teams.  • Proficiency in deep-dive product security investigations and root-cause analysis spanning design, code, configuration, and operational layers.  • Exploit analysis and proof-of-concept development that distinguishes real exploitability from theoretical risk.  • Familiarity with SDLC integration, CI/CD pipelines, SaaS threat models, and secure development practices.  Preferred Qualifications  • Experience in a PSIRT or similar function for a major software or SaaS platform.  • Recognized expertise in product security incident response, vulnerability research, or application security w
