Note: The job is a remote job and is open to candidates in USA. Avaya is hiring an Infrastructure Security Vulnerability Engineer to manage vulnerability identification, prioritization, tracking, and remediation across infrastructure and applications in a cloud-based FedRAMP Moderate environment supporting U.S. federal requirements. The role coordinates remediation with technical and risk teams, uses vulnerability assessment and cloud-based AI tools, and maintains risk reporting and process improvements.

Responsibilities

• Lead and coordinate vulnerability remediation activities across infrastructure and applications, ensuring identified vulnerabilities are tracked, prioritized, and resolved in accordance with established security requirements and remediation timelines
• Evaluate vulnerabilities using CVE and CVSS data, exploitability, threat intelligence, asset criticality, attack paths, exposure information, and other relevant risk indicators to help determine remediation priorities
• Support vulnerability remediation activities aligned with applicable CISA BOD 26-04 requirements and other relevant federal cybersecurity directives, including monitoring remediation progress against required deadlines
• Support vulnerability assessment and remediation across Windows Server 2019 and above, Linux/RHEL 9.x and above, and application environments. Work with technical teams to identify appropriate remediation approaches, including patching, configuration changes, and other corrective actions
• Use tools such as Tenable Security Center, Nessus, and Qualys to review vulnerability findings, validate remediation status, identify outstanding exposures, and support ongoing vulnerability management operations
• Partner with application owners, application managers, infrastructure teams, vendor managers, and risk partners to communicate findings, clarify remediation requirements, resolve technical or process-related questions, and drive issues to closure
• Maintain accurate vulnerability records in ServiceNow or other designated systems of record. Update remediation status, document actions taken, track outstanding items, and ensure records reflect the current state of identified vulnerabilities
• Coordinate patching and remediation activities with application and infrastructure teams, following established change management processes and supporting timely, controlled implementation of corrective actions
• Support vulnerability exception management, risk-based remediation decisions, incident-driven response activities, and escalation of overdue or unresolved vulnerabilities to the appropriate stakeholders
• Leverage cloud-based AI tools, where appropriate, to support vulnerability identification, analysis, prioritization, and remediation workflows while applying sound security judgment and established review processes
• Develop and maintain periodic vulnerability management metrics and reports, including remediation progress, aging vulnerabilities, overdue findings, risk trends, and other indicators used to communicate exposure and remediation effectiveness
• Identify opportunities to improve vulnerability management procedures, remediation workflows, reporting accuracy, and operational efficiency. Maintain clear documentation of findings, remediation activities, exceptions, and supporting processes
