• Demonstrated experience planning and leading Systems Engineering efforts. 
• Microsoft Defender for Endpoint (MDE): Proven engineering experience with MDE architecture, deployment strategies through MECM/SCCM or Intune, policy ring management, and advanced hunting using Kusto Query Language (KQL). 
• Trellix HX: Demonstrated experience engineering, deploying, and managing Trellix HX (formerly FireEye) controllers and agents within air-gapped or highly restricted networks, including the creation of OpenIOC and YARA rules. 
• Operating System & Forensic Knowledge: In-depth technical understanding of Windows, Linux, and macOS internals, including file systems, registry structures, and process-execution mechanics. 
• Compliance with DoD 8570/8140 IAM Level II or IAM Level III baseline certification requirements. 
• Bachelor's degree in Systems Engineering, Computer Science, Information Systems, Engineering Science, Engineering Management, or a related discipline from an accredited college or university.
