  • Ensure incidents, notifications, system outages, and follow-up actions are documented, communicated, reviewed, and escalated in accordance with company procedures.
  • Prepare the GSOC for growth and coordinate the transition of centralized functions to the future permanent GSOC while maintaining effective support for New Mexico.

  • 7+ years of experience in physical security, security operations, emergency communications, dispatch, or a security operations center or control room.
  • 2+ years leading, supervising, or coordinating security personnel or operational teams.
  • Experience coordinating incident response, escalations, shift coverage, and accurate operational reporting.
  • Experience using CCTV, access control, alarm monitoring, dispatch, or incident management systems.
  • High school diploma or GED and the ability to obtain and maintain a U.S. Government security clearance, if required for assigned work.

Preferred Skills and Experience

  • Experience in aerospace, defense, advanced manufacturing, critical infrastructure, or a government environment.
  • Experience developing standard operating procedures, training staff, reviewing incident reports, and tracking corrective actions.
  • Familiarity with security systems such as Lenel, Avigilon, or comparable access control and video platforms.
  • Strong written communication, sound judgement, discretion, and ability to stay composed during time-sensitive and high stress events.

Additional Requirements

  • Must be able to work onsite in New Mexico and support operational needs outside standard business hours, including occasional nights, weekends, or holidays.
  • Must successfully complete required background screening and obtain and maintain required background screening and obtain and maintain required site credentials and a U.S. Government security clearance, if required for assigned responsibilities.
