Job Description

We are looking for a senior vulnerability management specialist to run and uplift vulnerability management operations for one of our major clients, a large Australian enterprise based in Sydney. Tenable is the core platform, and you will own it day to day: scan coverage, data quality, prioritisation, remediation tracking and reporting across a large hybrid estate.

This is a hands-on operational role with real accountability. You will be the Tenable subject matter expert on the engagement, and the person infrastructure teams, service owners and security leadership rely on for a transparent view of exposure and what to fix first.

What you'll do
Operate and tune the Tenable platform day to day: scan policies and schedules, credentialed and agent-based scanning, scanner and agent health, asset tagging and access controls
Own scan coverage and data quality by reconciling Tenable against the CMDB, cloud inventories and endpoint tooling, then closing blind spots and authentication failures
Triage and prioritise findings on risk (VPR, CVSS, EPSS, known exploited vulnerabilities,



asset criticality and internet exposure) rather than raw severity counts
Drive remediation with infrastructure, cloud, network and application teams: raise and track work through the ITSM tool, agree treatment plans, hold owners to SLAs and verify fixes by rescan
Lead the response to critical and zero-day vulnerabilities, from rapid exposure assessment and targeted scans through to confirmed closure
Manage false positives, exceptions and risk acceptances with proper evidence, approval and expiry
Build dashboards and reporting for operational teams and executives covering coverage, SLA performance, ageing and risk trend, including evidence for Essential Eight and audit requirements
Automate and integrate using the Tenable API with Python or PowerShell, connecting vulnerability data to ITSM, CMDB, SIEM and patching tools
Document runbooks and operating procedures, and coach analysts and support teams so the capability outlasts the contract
