Future duties and responsibilities

• Vulnerability Triage and Risk Assessment

• Own security-specific vulnerability triage within the assigned execution crew — reviewing access control, privilege escalation, identity, and container security findings in the vulnerability management platform and making accurate risk assessments before routing to remediation.

• Identify false positives, risk acceptances, and exception cases that require security judgment rather than standard runbook execution.

• Validate risk scores against asset criticality and business context, re-scoring where automated triage requires human security expertise.

• Provide security sign-off on remediation approaches proposed by infrastructure and application engineers before high-risk fixes proceed to change management review.

• Access Control and Identity Remediation

• Remediate privilege escalation vulnerabilities across application, database, and container layers reviewing and revoking excessive service account permissions, cleaning up orphaned accounts, and enforcing least-privilege standards aligned to enterprise IAM governance.

• .Own credential and secrets management remediation for application and database credentials flagged in vulnerability scans coordinating with the platform team for vault integration and ensuring credentials are remediated within approved workflows.

• Remediate IAM misconfigurations surfaced through vulnerability scans — role-based access violations, dormant privileged accounts, and unauthorized elevation paths.

• Support quarterly access review processes for CGI-managed service accounts and automation pipeline credentials.

• Container and Application Security

• Own container security vulnerability triage reviewing Docker image CVEs, runtime security alerts, and container platform security findings routed from the centralized triage function.

• Perform container configuration reviews against enterprise security standards and flag non-compliant configurations for remediation.

• Create fix PRs for container-level vulnerabilities within the source control workflow, adhering to branching standards and pipeline configurations.

• Review and validate application security fix approaches proposed by Java and .NET

• developers specifically Spring Security misconfigurations, endpoint exposure vulnerabilities, OAuth misconfigurations, and API security gaps providing security perspective before fixes proceed to application team sign-off.

• Security Governance and Compliance

• . Maintain accurate POAM records for all security-classified vulnerabilities ensuring

• remediation dates, risk classifications, and fix approaches are documented to audit standards required in a regulated banking environment.

• . Prepare security evidence packages for regulatory audit requests pulling remediation history and pipeline execution logs from the vulnerability management platform and work management tools.

• .Identify and document risk acceptances for vulnerabilities that cannot be remediated within SLA windows, preparing justifications for information security sign-off.

• Support the change management process for security-classified changes by preparing security impact assessments for high-risk remediations.

• Collaboration and Escalation

• Work closely with Infrastructure Engineers, Java and .NET Developers, Database

• Administrators, and DevSecOps Engineers across all three crews providing security expertise that these roles do not own individually.

• .Escalate Critical and High severity security vulnerabilities immediately upon identification, providing technical context and recommended remediation approach to enable rapid response within defined SLA windows.

• Provide weekly security posture updates to the Delivery Manager covering open high-risk

• items, overdue security remediations, and emerging threat patterns from CISA KEV and vendor advisories.

• 6+ years of security engineering or security operations experience in enterprise environments with direct vulnerability remediation responsibility

• Vulnerability management platform experience POAM management, vulnerability record lifecycle, risk acceptance workflows, and reporting in a production environment

• Privileged access management and secrets management CyberArk or equivalent vault-based credential governance in an enterprise environment

• Access control and identity remediation privilege escalation CVE remediation, IAM misconfiguration fixes, service account cleanup, and least-privilege enforcement at scale

• Container security scanning experience alert triage, container vulnerability assessment, and integration with downstream remediation workflows

• Application security knowledge Spring Security, OAuth, endpoint exposure vulnerabilities, and API security misconfigurations sufficient to review and validate developer-proposed fixes
