Job description

- The Senior Tier 3 CrowdStrike Architect serves as the primary technical authority for the State of Iowa’s Enterprise Endpoint Detection and Response (EDR / XDR) platform.

- Operating within the Information Security Services (ISS) Bureau, this role is responsible for the overall architecture, administration, multi-tenant federation, fine-tuning, and escalation engineering of the CrowdStrike Falcon ecosystem across state agencies.

- This position acts as the highest level of technical escalation (Tier 3) for endpoint incidents, advanced threat hunting, platform troubleshooting, and complex integrations (such as Next-Gen SIEM, threat intelligence, and automated orchestration).

- Architect, implement, and maintain the state-wide CrowdStrike Falcon platform architecture across multi-tenant environments (CID hierarchy, RBAC, policy groups).

- Oversee sensor deployment strategies, policy prevention/detection tuning, custom rule creation (IOAs/IOCs), and feature rollout schedules across diverse agency environments.

- Manage CrowdStrike platform health, agent updates, host group management, and agent troubleshooting across Windows, macOS, Linux, and virtualized workloads.

- Act as the final technical escalation point for complex endpoint threats, zero-day vulnerabilities, and persistent malware identified by Tier 1/2 SOC analysts.

- Execute advanced containment, remediation, and live forensics using Real-Time Response (RTR) and custom scripts during critical incidents.

- Partner with SOC Analysts and Incident Response teams to refine playbooks, minimize Mean Time to Detect (MTTD) and Mean Time to Respond (MTTR), and drive risk reduction.

- Design and support telemetry integration between CrowdStrike Falcon, central SIEM/SOAR platforms, network defenses, and threat intelligence feeds.

- Introduce new integration ideas to better levergage existing security tools.

- Leverage CrowdStrike Fusion SOAR workflows to automate routine containment, notifications, and response actions.

- Align endpoint security strategies with Identity Threat Detection and Response (ITDR) and Cloud Security Posture Management (CSPM) modules as platform needs evolve.

- Translate complex technical threat data into actionable guidance for agency IT administrators and executive leadership.

- Develop dashboards using the CrowdStrike API to collect daily vulnerability data, and other key metrics, providing clear and actionable visibility into the enterprise environment.

- Develop standardized operating procedures (SOPs), deployment guides, and platform hardening specifications for state agency IT partners.

- Serve as the primary technical point of contact with CrowdStrike engineering and technical account managers (TAMs) to drive feature requests and resolve critical bugs.

- Provide formal and informal technical mentoring and training to Tier 1/2 SOC staff.

Required Technical Experience

- Platform Mastery: 4+ years of hands-on experience engineering, deploying, and maintaining CrowdStrike Falcon at enterprise scale (10,000+ endpoints).

- Tier 3 IR Capabilities: Demonstrated proficiency using CrowdStrike Real-Time Response (RTR), writing custom IOAs/IOCs, and performing endpoint threat hunting.

- OS & Scripting: Strong knowledge of Windows, Linux, and macOS internals, along with scripting capabilities (PowerShell, Python, Bash) for automated remediation and API integration.

- Security Ecosystems: Solid grasp of network security (firewalls, IDS/IPS), Identity & Access Management (AD/Entra ID), patch management, vulnerability assessments, and MITRE ATT&CK framework mapping.

Required Certifications (Must hold at least one active certification)

- CrowdStrike Specific (Highly Preferred):

Industry Certifications:

- Collaboration & Inclusion: Strong interpersonal skills with a commitment to fostering a diverse, supportive, and team-oriented working environment.

Preferred Qualifications

- Prior experience in state/local government (SLTT), higher education, or large-scale multi-tenant enterprise environments.

- Experience integrating CrowdStrike Falcon APIs with external automation platforms or SIEMs (e.g., Splunk, Microsoft Sentinel, Palo Alto Cortex).
