Team Excellence: Ensuring all mobile patrol officers are trained, motivated, and performing at a high level.
Operational Oversight: Maintaining seamless patrol coverage with minimal client complaints and full compliance with route and checkpoint protocols.
Strategic Collaboration: Working with the executive team to design incentive and training programs that foster engagement and reduce turnover.
Incident Management: Swiftly and effectively handling incidents on your account, documenting them same-night, and protecting our clients, officers, and company reputation.

Respond to incidents and emergencies on your account, ensuring client safety and satisfaction.
Review patrol reports and activity data to identify gaps in coverage and opportunities for improvement.
Maintain and submit same-night incident reporting in line with GCI's RapidResponse™ standard.

Who We’re Looking For

The ideal candidate is a proactive leader with a strong ability to drive results, motivate a team, and collaborate with senior leadership. You are:

Experienced: At least 2-3 years in a supervisory role in security, military, or law enforcement. Experience leading a team and managing day-to-day account operations.
Tech-Savvy: Comfortable using GPS patrol tracking, reporting tools, and other operational software.
A Communicator: Strong written and verbal communication skills with a focus on collaboration and problem-solving.
Disciplined: You lead by example, demonstrating reliability, punctuality, and a strong work ethic.
Physically Capable: Able to drive extended patrol routes, exit the vehicle to conduct walk-throughs, and respond quickly to incidents in all weather conditions.
Certified: Valid Unarmed Security Officer license for St. Louis City/County and a valid driver's license with a clean driving record and reliable transportation.

Benefits of Joining GCI Security

Competitive Pay: $22.00 - $24.00 per hour
Career Advancement: Clear pathways to higher leadership roles within the company.
