Key Responsibilities:

• Administer and optimize the Tenable One platform, ensuring complete coverage and automated scanning across the environment.
• Manage the full vulnerability lifecycle - from detection and prioritization of findings to remediation and verification.
• Lead and coordinate patch management activities in partnership with IT teams.
• Develop and deliver reporting and metrics to track vulnerability management (VM) performance and compliance status.
• Address compliance requirements and support audits by providing documentation, reports, and remediation evidence.
• Troubleshoot technical scanning issues and collaborate with network, infrastructure, and application teams to resolve them.
• Create and maintain technical design documents, including setup configurations, roadmaps, and process documentation to ensure future continuity.
• Mentor and support junior team members on tools, processes, and best practices.

• 5-10 years of experience in Vulnerability Management and 10-15 years overall in IT or Network Infrastructure roles.
• Strong hands-on experience with Tenable One and familiarity with vulnerability scanning, prioritization, and reporting.
• Solid understanding of network infrastructure (servers, routers, switches, endpoints).
• Proven experience driving patch management programs and coordinating with cross-functional teams.
• Familiarity with compliance frameworks (e.g., NIST, ISO, CIS) and experience supporting audit activities.
• Excellent documentation, communication, and troubleshooting skills.
• Certifications such as Security+, CEH, or Tenable Certified Professional are an asset.

Additional Notes:

The environment is already 60-70% scanned and configured; this role will focus on completing the remaining setup, implementing automated scans, managing compliance activities, and refining the roadmap for long-term program maturity.
