Overview
The Principal Security Monitoring and Response Analyst is the principal program lead and senior subject matter expert for the integrated Security Operations Center (SOC), Incident Response (IR), and Insider Threat capability. The role’s mission is to bring these operations together as one coordinated program, improving how Mastercard detects, investigates, responds to, and learns from cyber and insider threats while preserving functional ownership, investigative independence, and appropriate confidentiality.
The role sets program direction, establishes common standards, coordinates cross-functional delivery, and drives measurable improvements across people, process, and technology. It provides authoritative technical and operational leadership for complex incidents and ensures that modernization initiatives are adopted into business-as-usual operations.
In this role you will:
• Develop and govern the integrated SOC, IR, and Insider Threat program roadmap, aligning priorities, milestones, dependencies, risks, resources, capability gaps, and success measures with the wider multi-year modernization strategy.
• Act as the authority for integrated operating practices while respecting functional ownership and investigative independence.
• Integrate technology modernization into business-as-usual operations through clear process ownership, adoption plans, training, and sustained use.
• Define end-to-end operating models, standards, playbooks, escalation paths, decision rights, and handoffs across security monitoring and response.
• Define and monitor measures of operational speed, quality, consistency, preparedness, and effectiveness across detection, triage, investigation, containment, recovery, and post-incident improvement, supported by valid evidence.
• Serve as the senior SME for high-severity incidents and sensitive security matters, providing technical direction and cross-functional coordination while preserving appropriate confidentiality and need-to-know controls.
• Leverage threat intelligence, incident trends, insider threat findings, quality reviews, and root-cause analysis to drive continuous improvement across investigation methodologies, response workflows, escalation processes, and operational readiness.
• Validate operational readiness through exercises, simulations, and control testing in partnership with Security Engineering, Threat Intelligence, Vulnerability Management, Crisis Management, Legal, and stakeholders across the broader business.
• Own cross-functional operational issues through resolution, ensuring risks, decisions, actions are clearly documented and tracked.
• Influence functional leaders and delivery teams, building alignment, resolving cross-team friction, and ensuring agreed improvements are implemented and sustained.

• Extensive expertise leading enterprise incident response, forensic response, security monitoring, threat-led detection, threat hunting and complex investigations.
• Strong understanding of insider threat operations, including behavioral and technical indicators, case governance, legal and HR partnership, confidentiality, and evidence handling.
• Strong recent experience with Security Information and Event Management (SIEM) platforms.
• Demonstrated ability to design and mature operating models across global SOC, IR, Insider Threat, Threat Intelligence, engineering, and business response teams in complex, regulated environments.
• Experience applying automation, orchestration, analytics, and AI-assisted capabilities to improve detection quality, investigative speed, consistency, and analyst effectiveness.
• Ability to convert complex technical and operational issues into clear decisions, investment cases, executive communications, and measurable outcomes.
• Proven success leading strategic programs and influencing senior stakeholders, technical specialists, and partner functions without direct authority.
