Manage and track the remediation backlog, maintaining focus on risk reduction and measurable progress. Governance, Metrics & Continuous Improvement Report on vulnerability metrics and remediation status, collaborating closely with the Vulnerability Management Governance function. Review and approve exceptions or false-positive requests, balancing risk tolerance with operational realities. Perform root cause analysis on recurring or systemic vulnerability issues, driving long-term prevention strategies.

Hands-on experience with vulnerability management tools such as Qualys or similar platforms Familiarity with patch management, secure configuration standards (CIS, NIST, ISO 27001), and change management processes. Ability to develop scripts or automation (Python, PowerShell, Bash) to support data analysis and remediation workflows. Strong analytical mindset: able to interpret scan data, prioritise based on risk, and communicate actionable insights to both technical and non-technical audiences. Proven experience collaborating in cross-functional environments with security, DevOps, and infrastructure teams.
