Job summary

ServiceNow, Inc. seeks a senior staff-level product security engineer to lead PSIRT investigations and coordinate vulnerability responses across engineering, product, and release teams.

You will shape response strategy, own CVE processes, and drive postmortems, while maintaining strong communication with leadership and external partners. Strong Java/JavaScript, auditing, and SDLC security expertise are required.

Qualifications

• 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 12 years of related experience with a Bachelor's degree; or 8 years with a Master's degree; or a PhD with 5 years of experience; or equivalent experience.
• Minimum 5 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.
• Experience leading a CVE disclosure process, including CVE assignment, scoring (CVSS), and advisory publication.

Responsibilities

• 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.
• 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.
• Lead ServiceNow's CVE disclosure process—owning CVE assignment, scoring, advisory content, and publication timing.
• Collaborate with external security partners, vendors, and researchers on coordinated disclosures, aligning timelines and messaging across parties.
• Conduct technical accuracy reviews of external advisories, researcher write-ups, and joint disclosure content to ensure correctness before publication.
• Represent PSIRT's technical position in multi-party coordinated disclosures and researcher engagements.
• Author postmortems 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.
