What We Do

The Senior Security Engineer – Attack Surface Platforms serves as the subject matter expert for the organization’s external attack surface management (EASM) capability. This role leads platform operations, asset discovery coverage, exposure analysis, and remediation workflows for internet-facing assets. The engineer works across security and technology teams to validate findings, direct risk reduction, improve platform quality, and develop repeatable processes and targeted enhancements.

Essential Functions

· Serve as the technical subject matter expert for our EASM platform. Administer platform configuration, access, integrations, workflows, reporting, and operational health.

· Maintain reliable discovery and inventory of internet-facing assets, including domains, IP addresses, hosts, and services. Review coverage, data quality, changes, and newly observed assets to identify potential gaps or unmanaged exposure.

· Validate asset attribution and ownership by correlating EASM findings with available business, cloud, network, DNS, and inventory context. Identify unknown or potentially unauthorized assets and route them for investigation.

· Analyze external exposures such as vulnerable technologies, misconfigurations, exposed services, and assets that do not meet security standards. Prioritize response using exposure context, exploitability, business importance, and available threat information.

· Lead remediation coordination with cloud, network, infrastructure, application, and business teams. Clarify the risk and recommended action, track progress, verify closure, and escalate urgent or overdue exposures through established processes.

· Tune platform policies, risk settings, alerting, and exception workflows to improve signal quality and reduce duplicate or non-actionable findings. Document the rationale for material changes and validate results after implementation.

· Build and maintain integrations between the EASM platform and relevant asset inventory, ticketing, cloud security, or security operations systems. Troubleshoot data flow, mapping, ownership, and workflow issues with platform administrators and vendors.

· Develop targeted automation and platform enhancements using available APIs, scripts, dashboards, and workflow features to improve asset review, triage, reporting, and remediation tracking.

· Produce operational and management reporting on asset coverage, newly discovered assets, exposure trends, remediation status, recurring issues, and platform health. Explain data limitations and highlight items that require action.

· Lead EASM onboarding and change reviews for new domains, business units, cloud environments, brands, and acquisitions. Ensure discovery and ownership processes are updated as the organization changes.

· Support security investigations and incident response when an externally exposed asset or service may contribute to risk. Preserve relevant platform evidence and coordinate follow-up actions with response teams.

· Develop runbooks and standards for EASM operations. Guide platform users and partner teams on finding validation, ownership, prioritization, and effective remediation.
