Cybersecurity Vulnerability Scanning Engineer

• →

  Manage day-to-day operations of infrastructure vulnerability scanning using Tenable Vulnerability Management (e.g., Tenable.io/Tenable.sc), including scan scheduling, execution, and monitoring.

• →

  Configure, run, and maintain authenticated scans (credentialed checks) for Windows, Linux/Unix, and network devices, including credential management and troubleshooting failed authentications.

• →

  Perform Linux server system administration in support of the infrastructure vulnerability scanning platform (e.g., scanner hosts), including OS hardening, patching, performance monitoring, log review, certificate management, and troubleshooting.

• →

  Execute and tune non-authenticated scans for external and internal perspectives where applicable, ensuring safe scanning practices and minimal operational impact.

• →

  Maintain scan coverage and accuracy through target management, asset classification, exclusions, and scanner placement considerations.

• →

  Support vulnerability lifecycle activities by validating findings, reducing false positives, and partnering with infrastructure teams to enable effective remediation.

• →

  Develop and maintain operational runbooks and documentation for scan standards, credential onboarding, and troubleshooting procedures.

• →

  Produce recurring reporting and metrics on scan health, coverage, and results quality; support audit and compliance requests as needed.

• →

  Collaborate with teams responsible for CMDB/asset inventory, identity/privileged access, networking, and patching to improve scan efficacy and remediation outcomes.

• 5–7 years of cybersecurity experience, with demonstrated experience operating vulnerability scanning programs for infrastructure.

• Hands-on experience with Tenable Vulnerability Management, including scan policy configuration, scanners, targets/assets, and results analysis.

• Strong knowledge of authenticated (credentialed) scanning concepts and common credential types (local/domain accounts, SSH keys, SNMP, etc.).

• Working knowledge of Windows and Linux/Unix administration concepts (services, packages, patching, permissions) to support scan troubleshooting and validation.

• Solid understanding of networking fundamentals (TCP/IP, ports, routing, firewalls, VLANs) and how they affect scan reachability and performance.

• Ability to analyze vulnerability findings, prioritize based on risk/context, and communicate clearly with technical stakeholders.

• Experience tuning Tenable scan policies for performance and accuracy (safe checks, scan windows, throttling, exclusions, and plugin families).

• Familiarity with vulnerability management workflows and integrations (e.g., ServiceNow Vulnerability Response and CMDB/asset inventory alignment).

• Knowledge of network administration and routing protocols (e.g., BGP, OSPF, IS-IS).

• Experience with scripting/automation for scan operations and reporting (Python, PowerShell, Bash).

• Understanding of cloud and hybrid environments and related scanning approaches (e.g., IaaS workloads, segmented networks, and scanner placement).

• Relevant certifications (e.g., CompTIA Security+, Tenable certifications, GIAC, or equivalent).

• Bachelor’s degree in Cybersecurity, Information Technology, Computer Science, or a related field is desired (or equivalent practical experience).

• Minimum of 5–7 years of experience in cybersecurity, with emphasis on vulnerability scanning and infrastructure security operations.

• Familiarity with applying Artificial Intelligence (AI) or Machine Learning (ML) techniques in cybersecurity contexts (e.g., anomaly detection, threat hunting, behavioral analytics, or risk scoring).
