Senior CrowdStrike Falcon Architect

Senior CrowdStrike Falcon Engineer / Architect

We are looking for a senior CrowdStrike Falcon engineer / architect to serve as the Tier 3 technical authority for a large enterprise CrowdStrike Falcon EDR/XDR environment.

This is a hands-on CrowdStrike engineering and architecture position, not a general SOC analyst role. The person in this role will own advanced Falcon administration, enterprise architecture, endpoint security policy, detection tuning, threat hunting, incident response, Real-Time Response (RTR), IOA/IOC development, Falcon API integrations, automation, and complex Tier 3 troubleshooting.

The environment includes 10,000+ endpoints across multiple agency environments, so experience managing CrowdStrike Falcon at enterprise scale is critical.

What You Will Work On

CrowdStrike Falcon Architecture & Engineering

• Architect, administer, and maintain the enterprise CrowdStrike Falcon platform across multiple environments.
• Manage Falcon CID hierarchy, RBAC, host groups, security policies, sensor deployment, and prevention and detection controls.
• Develop and tune CrowdStrike prevention, detection, and response policies.
• Create and maintain custom IOAs and IOCs.
• Manage CrowdStrike sensor deployment, upgrades, agent health, and troubleshooting.
• Support Falcon across Windows, Linux, macOS, and virtualized workloads.
• Evaluate new CrowdStrike capabilities and determine how they should be deployed across the enterprise.

Tier 3 Incident Response & Threat Hunting

• Act as the highest-level technical escalation point for complex endpoint security incidents.
• Investigate advanced malware, persistent threats, zero-day vulnerabilities, and sophisticated endpoint activity.
• Perform advanced threat hunting and endpoint investigation using CrowdStrike Falcon.
• Use CrowdStrike Real-Time Response (RTR) for live investigation, containment, remediation, and forensic activities.
• Develop scripts and response actions for complex endpoint incidents.
• Analyze endpoint activity and map adversary behavior to MITRE ATT&CK.
• Partner with SOC and Incident Response teams to improve detection and response processes.

Integration, API & Security Automation

• Integrate CrowdStrike Falcon with enterprise SIEM, SOAR, threat intelligence, network security, and identity security platforms.
• Develop and support CrowdStrike Falcon API integrations.
• Build security automation using PowerShell, Python, and Bash.
• Develop automated response workflows using CrowdStrike Fusion.
• Support integrations with platforms such as Splunk, Microsoft Sentinel, Palo Alto Cortex, and other security technologies.
• Identify opportunities to automate endpoint investigation, containment, remediation, reporting, and operational tasks.

Enterprise Platform Management

• Monitor overall CrowdStrike platform health, endpoint coverage, sensor status, and policy effectiveness.
• Develop dashboards and reporting through the CrowdStrike API for vulnerabilities, detections, endpoint status, and security metrics.
• Create technical standards, deployment procedures, SOPs, and platform hardening documentation.
• Work directly with CrowdStrike Engineering and Technical Account Managers on complex product issues, bugs, and technical escalations.
• Provide technical guidance and mentoring to Tier 1/Tier 2 security teams.
