• Communicate priorities, risk tradeoffs, and program performance to senior leadership and cross-functional stakeholders.
• Scale product security capabilities, including threat modeling, application security testing, vulnerability management, and developer enablement.
• Lead detection engineering, incident response, threat intelligence, monitoring, and threat hunting capabilities.
• Guide high-severity incidents, complex investigations, and security reviews, driving durable remediation of systemic issues.
• Establish standards for control coverage and effectiveness across applications, cloud, identity, and endpoints.
• Manage program budgets and strategic security vendors.

This opportunity is for you if you have:

• 7+ years of cybersecurity experience across product, application, or infrastructure security, plus security operations, incident response, or detection engineering.
• 4+ years managing experienced security engineers or multidisciplinary technical teams.
• Strong communication skills and the ability to navigate sensitive decisions with technical teams and senior leaders.
• Experience defining strategy and delivering measurable outcomes across multiple security disciplines.
• Experience building or scaling product security programs with Product and Engineering teams.
• Strong knowledge of secure software development, threat modeling, application security testing, vulnerability management, and cloud-native architectures.
• Strong knowledge of incident response, detection engineering, SIEM, EDR, cloud security, and identity security.
• Experience translating ambiguous risks into prioritized, cross-functional programs and driving remediation through influence.
• Experience managing budgets, MSSPs, testing firms, or other security providers.
• Authorization to work in the United States, as Calendly does not provide immigration sponsorship at this time.
