Senior Security Engineer Attack Surface Platforms (Remote)

·    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.

Partners with Security Operations, Cloud Engineering, Network Engineering, Infrastructure, application teams, IT asset owners, Security Architecture, and business stakeholders. Works with the EASM vendor and internal platform teams to resolve issues, assess product capabilities, and plan changes that improve external visibility and remediation outcomes.

·    Hands-on experience operating an external attack surface management or attack surface management platform (EASM or CTEM).

·    Strong understanding of internet-facing assets, common network services and protocols, DNS, web infrastructure, cloud-hosted resources, and how external exposure can create security risk.

·    Experience validating vulnerability, exposure, and misconfiguration findings and prioritizing remediation using technical evidence and business context.

·    Working knowledge of at least one major cloud platform, including its core services and terminology; experience across multiple cloud platforms is useful.

·    Experience integrating security platforms with asset inventory, ticketing, cloud security, or security operations systems and troubleshooting data quality or workflow issues.

·    Ability to use APIs or basic scripting in a language such as Python, PowerShell, or Bash to investigate findings, validate data, and support platform enhancements.

·    Ability to establish clear ownership and remediation paths for findings and to communicate risk and recommended actions to technical and nontechnical stakeholders.

·    Strong analytical, written, and verbal communication skills; able to manage work independently, guide cross-functional remediation, and provide technical direction to peers.

Generally requires a bachelor’s degree in Computer Science, Information Technology, Engineering, or a related field, or equivalent practical experience.

Typically requires 4–6 years of experience in information security, external attack surface management, vulnerability management, cloud security, security operations, or a related technical role. Hands-on EASM platform experience is required; Cortex Xpanse experience is strongly preferred.

Candidates must hold at least one foundational cloud or cloud security certification at the time of selection. The certification must demonstrate familiarity with cloud concepts and the core services and terminology of at least one major cloud provider or be broadly applicable across all security domains. Additional certifications or formal credentials in application security, secure software development, vulnerability management, or cloud security are preferred.

First American will consider for employment all qualified applicants, including those with arrest or conviction records, in a manner consistent with the requirements of applicable state and local laws (e.g., the Los Angeles County Fair Chance Ordinance for Employers and the California Fair Chance Act).

First American intends to conduct a review of an applicant’s criminal history in connection with a conditional offer. First American reasonably believes that a criminal history may have a direct, adverse and negative relationship with the following material job duties for this position potentially resulting in the withdrawal of the conditional offer of employment: handling of confidential, proprietary or trade secret information belonging to First American or its customers, administrating or facilitating financial transactions, and the ability to meet customer-imposed criminal history requirements.
