Title and Summary
Principle, Vulnerability Analyst
Overview
• The AI Vulnerability Operations team is responsible for turning AI-identified security findings into validated, prioritized, and remediated risk reduction across Mastercard's software environment.
• This position is for a Principal Vulnerability Analyst who will work directly with application, engineering, product, and security teams to validate vulnerabilities identified through AI models and drive them through remediation.
• The role will focus on determining whether AI-generated findings are exploitable, relevant, reachable, and material to the application or service being evaluated.
• This position will help translate AI model outputs into clear technical guidance, remediation actions, risk decisions, and measurable vulnerability reduction outcomes.
• The Principal Vulnerability Analyst will also provide feedback into AI vulnerability workflows to improve model precision, reduce false positives, identify missed context, and strengthen operational processes over time.
Role
• Validate vulnerabilities identified by AI models by reviewing code context, dependency data, application architecture, runtime exposure, compensating controls, and exploitability evidence.
• Partner with application and engineering teams to confirm ownership, assess impact, determine remediation options, and drive vulnerabilities to closure.
• Translate AI-generated vulnerability findings into clear, actionable remediation guidance that engineering teams can implement efficiently.
• Triage AI findings to distinguish true positives, false positives, duplicates, accepted risks, configuration issues, dependency issues, and findings requiring additional analysis.
• Assess vulnerability severity using available evidence, including exploitability, reachability, data sensitivity, business criticality, external exposure, dependency paths, and compensating controls.
• Facilitate remediation discussions with product owners, developers, security engineers, and platform teams to remove blockers and maintain momentum on high-risk issues.
• Verify remediation outcomes by reviewing code changes, dependency updates, configuration changes, compensating controls, retest results, and supporting evidence.
• Document validation rationale, remediation decisions, residual risk, and closure evidence in vulnerability tracking and reporting systems.
• Identify patterns across AI-generated findings and recommend improvements to secure coding practices, dependency management, build processes, and application security controls.
• Provide feedback to AI model, data, and platform teams on finding quality, missing context, false positives, false negatives, prompt or workflow gaps, and opportunities for better prioritization.
• Support prioritization of AI-identified vulnerabilities across critical, externally exposed, and high-risk applications to ensure remediation efforts focus on the areas of greatest risk.
• Create playbooks, decision trees, validation standards, and remediation guidance to make AI vulnerability operations more consistent and scalable.
• Mentor analysts and engineers on vulnerability validation, risk-based prioritization, secure remediation practices, and effective engagement with application teams.
• Prepare executive-ready summaries, risk narratives, metrics, and status updates that communicate remediation progress, blockers, and residual risk.
• Continuously improve the AI vulnerability validation lifecycle by reducing manual effort, improving evidence quality, and strengthening handoffs between AI tooling, analysts, and engineering teams.
All About You
• Strong experience in vulnerability management, application security, secure software development, or security engineering, with demonstrated ability to validate and drive remediation of software vulnerabilities.
• Deep understanding of common vulnerability classes, secure coding practices, OWASP, CWE, CVSS, exploitability analysis, threat modeling, and risk-based prioritization.
• Experience reviewing source code, dependency manifests, software composition analysis results, static analysis findings, container findings, configuration evidence, and application architecture to determine real-world risk.
• Ability to work directly with application teams to explain vulnerabilities, recommend practical fixes, resolve disagreements, and drive remediation to completion.
• Strong analytical judgment to evaluate AI-generated findings, identify false positives, determine missing context, and distinguish theoretical risk from exploitable risk.
• Experience with vulnerability tracking, remediation workflows, exception handling, risk acceptance, retesting, and closure evidence.
• Familiarity with AI-assisted security workflows, including how model-generated findings can be validated, enriched, prioritized, and improved through analyst feedback.
• Ability to communicate complex vulnerability details clearly to developers, product owners, security leaders, and non-technical stakeholders.
• Strong written documentation skills, including the ability to produce validation notes, remediation guidance, risk narratives, executive summaries, and operational playbooks.
• Experience collaborating across security, software engineering, product, platform, and operations teams in a large enterprise environment.
• Strong leadership qualities, including mentoring, influencing without authority, driving accountability, and creating repeatable processes for others to follow.
• Comfortable working in ambiguous, evolving environments where new AI-enabled workflows, tools, and processes are being developed and refined.
• Ability to identify process improvements that reduce remediation friction, improve customer experience, and increase the quality and speed of vulnerability closure.
