Job Description

Are you passionate about protecting critical infrastructure and driving proactive security? We're looking for an individual who's ready to take ownership of our vulnerability management ecosystem and lead the charge in deploying and optimizing Tenable Nessus and Tenable SC platforms.
This is more than a technical role, it's a mission-critical opportunity to shape how we defend our environments, empower our teams, and meet the highest standards of compliance and resilience. You'll be the go-to expert, collaborating across departments to ensure our systems are secure, our risks are visible, and our responses are swift.
If you thrive in fast-paced environments, love solving complex problems, and want to make a real impact, this is your chance to be at the forefront of enterprise security.
What you will be doing:

• Lead deployment, configuration, and lifecycle management of Tenable Nessus and Tenable.SC across varied environments.
• Design and execute vulnerability scanning strategies aligned with business priorities and risk appetite.
• Validate results, investigate anomalies, and coordinate remediation with infra, network, hosting, and app teams.
• Maintain gold-standard documentation (guides, SOPs, user manuals).
• Build tailored dashboards and reports to drive visibility and informed decision-making.
• Embed vulnerability management into IT, security, and compliance workflows and planning.
• Provide training and mentorship to foster security awareness and technical excellence.
• Ensure practices meet Cyber Essentials Plus and ISO 27001 requirements, supporting audits and certification.
• Identify gaps, implement enhancements, and drive automation for continuous improvement.
• Integrate Tenable tools with SIEM, CMDB, and ticketing systems to streamline workflows.
• Serve as SME in vulnerability management for incident response, risk assessments, and architecture reviews.
• Represent the function in cross-functional forums, steering committees, and client engagements.
• Oversee patching strategies to achieve high compliance with infra and application teams.

What you will bring:

• Knowledge of leading the deployment, configuration, and lifecycle management of Tenable Nessus and Tenable.SC across diverse infrastructure environments.
• Designing and execution of comprehensive vulnerability scanning strategies that align with the client business priorities and risk appetite.
• Making security recommendations based on market intelligence and new security threats.
• Validating scan results, investigating anomalies, and coordinating remediation efforts with infrastructure, hosting, networks and application teams.
• Working knowledge of developing and overseeing patching strategies, working with infrastructure and application teams to achieve high levels of compliance each month.
• Familiarity and understanding of ISO27001, GDPR and NIST
• Certification such as CISSP, CISM, CEH, or SC-200, AZ-500
