## Description

As a Senior Consultant in Guidehouse's cyber practice, you will lead the design, implementation, and continuous improvement of SIEM capabilities for a federal law enforcement agency's classified environment. You'll combine hands on SIEM engineering with client facing consulting: translating mission risk into actionable detections, mentoring junior engineers/analysts, and advising stakeholders on monitoring strategy, metrics, and governance. This blend reflects Guidehouse's model where senior consultants drive client outcomes, contribute to business development, and support people development across the engagement.

What You Will Do :

You will design, implement, and support security information and event management (SIEM) capabilities for a federal law enforcement agency's classified data processing systems directorate. You will monitor, analyze, and correlate security events across classified environments to identify potential threats, vulnerabilities, and anomalous activity. Working closely with cybersecurity, network, and systems teams, you will configure log ingestion, develop detection use cases, tune alerts, and support incident response and forensic investigations. You will also support system authorization and continuous monitoring activities, maintain SIEM documentation, and ensure security monitoring solutions align with federal standards and mission requirements.

Responsibilities include, but are not limited to:

 * Lead SIEM strategy workshops, roadmap development, and stakeholder presentations.
 * Architect log ingestion pipelines, develop correlation rules, dashboards, and KPIs.
 * Align monitoring to NIST SP 800-53 and ISCM requirements.
 * Extend SIEM coverage to AWS/Azure/GCP.
 * Integrate SIEM with SOAR and automate enrichment.
 * Establish content lifecycle governance and mentor junior staff. Business
