Lead architecture, deployment, and operationalization of Tenable One platform across global IT and OT environments. | Senior-level experience in cybersecurity engineering with hands-on skills in Tenable One platform deployment and integration. | Senior Cybersecurity Engineer - Tenable One Company is looking for a senior-level cybersecurity engineer to lead the architecture, deployment, and operationalization of the Tenable One exposure management platform across a global data center and colocation environment. This role spans both traditional IT vulnerability management and OT/IoT security — including building management systems, power and cooling infrastructure, and other critical facility technology. This is a hands-on senior individual contributor role. The engineer will own technical design decisions, drive the build, and hand off a running, measurable program to the customer's security operations team. Key Responsibilities Architecture Design the end-to-end Tenable One architecture: scanner/sensor placement, network segmentation considerations, data flow, and integration points across a distributed global footprint. Produce a target-state architecture and phased deployment roadmap covering IT and OT/IoT scopes. Define asset discovery, tagging, and grouping strategy to support accurate exposure scoring and business-context reporting. Advise on passive vs. active collection methods in sensitive OT environments where active scanning carries operational risk. Deployment Deploy and configure Tenable One and its component modules — Tenable Vulnerability Management, Tenable Security Center, Tenable OT Security, Nessus scanners, Nessus Agents, and Tenable Identity Exposure / Attack Surface Management as scoped. Stand up scan policies, credentialed scanning, agent deployment at scale, and scan scheduling aligned to customer change windows. Build integrations with adjacent systems: CMDB/ITSM (ServiceNow), SIEM, ticketing, identity, and cloud provider accounts. Validate coverage and data quality; remediate scan gaps, credential failures, and false positives. Operationalization Establish the vulnerability and exposure management operating model: SLAs, risk-based prioritization, remediation workflows, exception handling, and escalation paths. Build dashboards and executive-level reporting on exposure posture, remediation velocity, and coverage. Automate recurring workflows (ticket creation, asset reconciliation, reporting) via API and scripting. Document runbooks, standard operating procedures, and knowledge transfer materials; train customer analysts and engineers. Partner with IT, OT/facilities, and application owners to drive adoption and remediation accountability. We strive to create an environment where all employees are empowered to succeed based on their skills, performance, and dedication. Our goal is to cultivate a culture of belonging that encourages innovation, collaboration, and respect for all team members, ensuring that WWT remains a great place to work for All! Equal Opportunity Employer Please inform candidates that this is a contract role with your company and will be assigned to a third?party customer of World Wide Technology. We’re committed to pay transparency. We ask that when posting a role with WWT please include a clear salary or pay range to support fairness and informed decisions.
