- Reducing exposure windows by driving coordinated response across affected releases, balancing risk and remediation feasibility
- Managing CVE and coordinated disclosure processes, including CVE assignment, scoring, advisory content, and publication timing
- Conducting technical accuracy reviews of external advisories and researcher write-ups
- Authoring root cause analyses and driving lessons learned to closure following product security incidents
- Participating in retrospectives and translating findings into concrete process and technical improvements
- Contributing to SDLC improvement areas and feeding incident learnings upstream into secure development practices
Requirements:
- 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

- Written and verbal communication of complex security risk 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 in leveraging or critically thinking about how to integrate AI into work processes, decision-making, or problem-solving
Preferred Qualifications:
- Experience in a PSIRT or similar function for a major software or SaaS platform

- Experience conducting vulnerability assessments on the ServiceNow platform
